CODE CORRELATION COMMITTEE December 9, 2011

The following items are code change proposals submitted for the IGCC, PV 2.0 that appear to be editorial in nature with no technical change. These will be considered by the Code Correlation Committee. The Code Correlation Committee will determine if they agree that the change is editorial, and then will approve the change or disapprove it. If the committee does not agree that the item is editorial, the proposed change will be submitted to the IGCC Code Development Committee for consideration.

CCC-IgCC-1-11 CODE SECTION 404.1.1 [formerly 402.3.3.1] Reference Code Changes: GG166, GG211, GG216 and GEW 465. Description: RESOLVING SECTION 404.1.1 (402.3.3.1) RECOMMENDED FINAL VERSION OF Sec. 404.1.1 404.1.1 Water for outdoor landscape irrigation. Outdoor landscape irrigation systems shall be designed and installed to reduce potable water use by 50 percent from a calculated mid- summer baseline in accordance with Section 404.1.2 or the system shall be supplied with alternate non-potable on-site water complying with Chapter 7.

Exceptions: Potable water is permitted to be used as follows:

1. During the establishment phase of newly planted landscaping. 2. To irrigate food production. 3. To supplement non-potable water irrigation of shade trees provided in accordance with

Section 408.2.3. 4. Potable water is permitted for landscape irrigation where approved by local ordinance or

regulation. GG211 AS revised the paragraph – not the exceptions – as follows: 402.3.3.1 Water for outdoor landscape irrigation. Water used for Outdoor landscape irrigation systems shall be designed and installed to reduce potable water use by 50 percent from a calculated mid- summer baseline in accordance with Section 402.3.3.2 or the system shall be supplied with non-potable water and shall comply in accordance with Section 406.2.

GG166 AS revised the paragraph – not the exceptions – as follows:

402.3.3.1 404.1.1 Water for outdoor landscape irrigation. Water used for outdoor landscape irrigation shall be non-potable and shall comply with Section 406.2 the graywater, municipal reclaimed water and collected rainwater provisions of Chapter 7.

GEW 465 AS – revised the paragraph – not the exceptions – as follows:

402.3.3.1 Water for outdoor landscape irrigation. Water used for outdoor landscape irrigation shall be alternate non-potable on-site water and shall that complyies with Section 406.2.

GG216 AS revised the exception - but not the paragraph – as follows: 402.3.3.1 Water for outdoor landscape irrigation. Water used for outdoor landscape irrigation shall be non-potable and shall comply with Section 406.2.

Exceptions: Potable water is permitted to be used as follows:

CODE CORRELATION COMMITTEE ACTIONS Page 1 of 35

1. During the establishment phase of newly planted landscaping. The establishment phase shall be not longer than the following: 1.1. 3 years for trees 1.2. 2 years for shrubs 1.3. 1 year for herbaceous cover plants

2. To irrigate food production. 3. To supplement non-potable water irrigation of shade trees provided in accordance with

Section 404.2.3. 4. Potable water is permitted for landscape irrigation where approved by local ordinance or

regulation. REASON: The main paragraph of the recommended final version is mostly based on GG211. The differences from GG211 are:

1. GG166 renumbers the section and because of other reorganization the references are changed. Specifically it changes the reference for non-potable waters from 406.2 to Chapter 7.

2. GEW 465 lumps all the non-potable water types into a single term: “alternate non potable on-site water”. I felt that took precedence over GG166’s specific listings.

3. Each change used different phrasing to send you to the requirements in 406.2 (Chapter 7), I suggest simple phrase ‘complying with’.

The exceptions are only affected by GG216 – but the changed section number reflects the reorganization of the chapter under GG166.


CCC-IgCC-2-11 CODE SECTION 405.1.4.1 [formerly 406.5.1] Reference Code Changes: Existing PV2.0 format – no related change in 2011. Description: Proposal is to change Exception into a 4th item.

405.1.4 Soil reuse and restoration. Soils that are being placed or replaced on a building site shall be prepared, amended and placed in a manner that establishes or restores the ability of the soil to support the vegetation that has been protected and that will be planted. Soil reuse and restoration shall be in accordance with Sections 405.1.4.1 and 405.1.4.2.

405.1.4.1 Preparation. Before placing stockpiled or imported topsoils, compliance with all of the following shall occur:

1. Areas shall be cleared of debris including, but not limited to, building materials, plaster, paints, road base type materials, petroleum based chemicals, and other harmful materials.

2. Areas of construction-compacted subsoil shall be scarified. 3. The first lift of replaced soil shall be mixed into this scarification zone to improve the transition

between the subsoil and overlying soil horizons. 4. Scarification is prohibited in all of the following locations:

4.1. Where scarification would damage existing tree roots. 4.2. On inaccessible slopes. 4.3. On or adjacent to trenching and drainage installations. 4.4. On areas intended by the design to be compacted such as abutments, footings, inslopes. 4.5. Brownfields. 4.6. Other locations where scarification would damage existing structures, utilities and

vegetation being preserved. Reason: The ‘exception’ is not exactly an exception from the regulation, but is more stringent than an exception. It is a prohibition of an activity. As such it needs to be considered on equal footing with the other 3 items (requirements) for soil preparation.


CCC-IgCC-3-11 SECTION 505.1, FORMERLY SECTION 503.1. Reference Code Change Proposal: GG146-11 AMPC1. Description: Coordination of Section 505.1, formerly Section 503.1, with proposed changes to Section 303.1, formerly Section 304.1.

RECOMMENDED FINAL VERSION

505.1 Material selection and properties. Building materials shall conform to Section 505.2.

Exceptions:

1. Electrical, mechanical, plumbing, security and fire detection, and alarm equipment and controls, automatic fire sprinkler systems, elevators and conveying systems shall not be required to comply with Section 505.2.

2. Where a whole building life cycle assessment is performed in accordance with Section 303, compliance with Section 505.2 shall not be required. REASON: Approved code change proposal GG146-11 AMPC1 revised Section 303.1 to indicate that where it is complied with, compliance with Section 505 is not required. The changes proposed by staff to Section 505.1 are intended to coordinate this concept fully by indicating this information within the text of Section 505.1 as well. This will help to ensure that future changes will consider the intrinsic ties between these sections and make users aware that they have this option as they strive to comply with Section 505.

Section 303, formerly Section 304, as it will appear in the 2012 IgCC: SECTION 303 WHOLE BUILDING LIFE CYCLE ASSESSMENT 303.1 Whole building life cycle assessment. Where a whole building life cycle assessment is performed in accordance with Section 303.1, compliance with Section 505 shall not be required. The requirements for the execution of a whole building life cycle assessment shall be performed in accordance with the following:

1. The assessment shall demonstrate that the building project achieves not less than a 20 percent improvement in environmental performance for global warming potential and at least two of the following impact measures, as compared to a reference design of similar useable floor area, function and configuration that meets the minimum energy requirements of this code and the structural requirements of the International Building Code. For relocatable buildings, the reference design shall be comprised of the number of reference buildings equal to the estimated number of uses of the relocatable building. 1.1. Primary energy use. 1.2. Acidification potential. 1.3. Eutrophication potential. 1.4. Ozone depletion potential. 1.5. Smog potential. 2. The reference and project buildings shall utilize the same life cycle assessment tool. 3. The life cycle assessment tool shall be approved by the code official.


4. Building operational energy shall be included. For relocatable buildings, an average building operational energy shall be estimated to reflect potential changes in location, siting, and configuration by adding or subtracting modules, or function. 5. Building process loads shall be permitted to be included. 6. Maintenance and replacement schedules and actions for components shall be included in the assessment. For relocatable buildings, average transportation energy, material, waste generation associated with reuse of relocatable buildings shall be included in the assessment. 7. The full life cycle, from resource extraction to demolition and disposal, including but not limited to, on-site construction, maintenance and replacement, relocation and reconfiguration, and material and product embodied acquisition, process and transportation energy, shall be assessed.

Exception: Electrical and mechanical equipment and controls, plumbing products, fire detection and alarm systems, elevators and conveying systems shall not be included in the assessment. 8. The complete building envelope, structural elements, inclusive of footings and foundations, and interior walls, floors and ceilings, including interior and exterior finishes, shall be assessed to the extent that data is available for the materials being analyzed in the selected life cycle assessment tool. 9. The life cycle assessment shall conform with the requirements of ISO 14044.


CCC-IgCC-4-11 CODE Tables 602.1.2.1, 602.1.2.2, and 602.2.1 Reference Code Changes: GEW 9, GEW 49 and existing PV 2.0 format) Description: Proposal is to delete the ‘a’ footnotes from each of these tables.

Reason: The footnotes to these three tables provide information best suited to a commentary. They neither adjust values in the table or specify how they are to be applied. They merely tell the code user where the information in the table comes from – similar to a footnote in a scientific article. If deletion of these footnotes is approved, the information will be moved to the future IgCC Commentary.


CCC-IgCC-5-11 CODE SECTION(S) # 603.2 (formerly 604.2) Reference Code Changes: GEW 82, 86, 87, 90 and 91 Proposed reformat – Section 603.2 recommended final version. 603.2 Energy distribution design requirements and load type isolation in buildings. Energy distribution systems within, on or adjacent to and serving a building shall be designed so that each primary circuit, panel, feeder, piping system or supply mechanism supplies only one of the energy use categories specified in Table 603.2. The energy use category served by each distribution system shall be clearly designated on the energy distribution system with the use category served, and adequate space shall be provided for installation of metering equipment or other data collection devices, temporary or permanent, to measure the energy used. The energy distribution system shall be designed to facilitate the collection of data for each of the building energy use categories in Section 603.3 and for each of the energy use categories specified in Table 603.2. Where there are multiple buildings on a building site, each building shall comply separately with the provisions of Section 603. Exception: Buildings designed and constructed so that the total usage of each of the load types specified in Table 603.2 is permitted to be measured through the use of installed sub-meters or other equivalent methods as approved.

TABLE 603.2 ENERGY USE CATEGORIES

Load Category Description of energy use Total HVAC system Heating, cooling and ventilation including, but not limited to fans, pumps,

boilers, chillers and water heating.

Total lighting system Interior and exterior lighting used in occupant spaces and common areas

Plug loads Devices, appliances and equipment connected to convenience receptacle outlets

Process loads Any single load of an activity within the building that exceeds 5 percent of the peak connected load of the whole building including, but not limited to data centers, manufacturing equipment and commercial kitchens

Building operations and other miscellaneous loads

Loads not includes elsewhere in this table including, but not limited to, vertical transportation systems, automatic doors, motorized shading systems, ornamental fountains, ornamental fireplaces, swimming pools, in-ground spas, snow-melt systems and exterior lighting that is mounted on the building or used to illuminate building facades

Reason: The original format of the section was inconsistent with typical I-Code format. The subsections 603.3.1 through 603.3.5 do not contain any regulations but are merely descriptors (definitions) of 5 energy use (load) categories. The regulation contained in Section 603.2 is require each type of load /energy use to be separately metered. This proposal turns Sections 603.3.1 through 603.3.5 into a table of energy use types. It then revises the paragraph to refer to the table. It also provides consistency in the language used regarding ‘load types’ and ‘categories’. The code changes are incorporated into the new format.

Description: Change Section 603.2 as it appeared in PV 2.0

603.2 Energy distribution design requirements and load type isolation in buildings. Energy distribution systems within, on or adjacent to and serving a building shall be designed such that each primary circuit, panel, feeder, piping system or supply mechanism supplies only one energy use type as defined in Sections 603.3.1 through 603.3.5. The energy use type served by each distribution system shall be clearly designated on the energy distribution system with the use served, and adequate space shall be provided for installation of metering equipment or other data collection devices, temporary or permanent, to measure their energy use. The energy distribution system shall be designed to facilitate the collection of data for each of the building energy use categories in Section 603.4 and for


each of the end use categories listed in Sections 603.3.1 through 603.3.5. Where there are multiple buildings on a building site, each building shall comply separately with the provisions of Section 603. Exception: Buildings designed and constructed such that the total usage of each of the load types described in Sections 603.3.1 through 603.3.5 shall be permitted to be measured through the use of installed sub-meters or other equivalent methods as approved. ventilation to the building including, but not limited to, fans, pumps, boiler energy, chiller energy and hot water. 603.3.1 HVAC system total energy use. This category shall include all energy used to heat, cool, and provide ventilation to the building including, but not limited to, fans, pumps, boiler energy, chiller energy and hot water. 603.3.2 Lighting system total energy use. This category shall include all interior and exterior lighting used in

occupant spaces and common areas. 604.3.4 603.3.3 Plug loads. This category shall include all energy use by devices, appliances and equipment

connected to convenience receptacle outlets. 604.3.6 603.3.4 Process loads. This category shall include the energy used by any single load associated with

activities within the building such as, but not limited to, data centers, manufacturing equipment and commercial kitchens that exceeds 5 percent of the total energy use of the peak connected load of the whole building. 604.3.3 603.3.5 Energy used for building operations loads and other miscellaneous loads. This category shall

include all energy use by vertical transportation systems, automatic doors, motorized shading systems, ornamental fountains and fireplaces, swimming pools inground spas, snow-melt systems, exterior lighting that is mounted on the building or used to illuminate building facades and all other building operations and the use of any miscellaneous loads in the building not specified in Sections 603.3.1 through 603.3.4. 604.3.6 Miscellaneous loads. Energy use for building operations and other operational loads.


CCC-IgCC-6-11 CODE SECTION(S) # 603.3.7.2 and 603.3.7.3 Reference Code Changes: GEW 96 Description: 603.3.7.2 Solar thermal. Equipment and systems providing heat to fluids or gases through the capture of solar energy shall be capable of being metered so that the peak thermal energy (Btu/hr) provided to the building and its systems or to off-site entities can be determined at 15 minute intervals and the amount of heat captured (Btu) for delivery to the building and its systems can be determined intervals of one hour or less.

Exception: Systems with a rated output of less than 100 kBtu/hr need not be metered.

603.3.7.3 Waste heat. Equipment and systems providing energy through the capture of waste heat shall be capable of being metered so that the amount of heat captured and delivered to the building and its systems can be determined at intervals of one hour or less.

Exception: Systems with a rated output of less than 100 kBtu/hr need not be metered. Reason: GEW 96 added the identical exception to Sections 603.3.7.2 and 603.3.7.3. The exception is an incomplete sentence and doesn’t’ clearly state what the exception is to. These 2 sections require each of these energy sources to be metered and then specifies the intervals at which the energy use is metered. GEW 96 states that the costs of metering small systems is disproportional to any results that the metering would provide. The intent of the proponent is to waive the metering requriements for small systems The additional text proposed for each exception clarifies the intent of the original code change.


CCC-IgCC-7-11 CODE SECTION(S) # 606.4 and Table 606.4 (formerly 607.5) Reference Code Changes: None – Original format in PV1.0 and 2.0 Proposed reformat – Section 606.4 final recommended version. 606.4 Heating, ventilation and air conditioning (HVAC) piping insulation. Piping with a nominal diameter greater than ¼ inch, including associated valves, fittings and piping system components, in heating, ventilation and air conditioning (HVAC) systems shall be thermally insulated in accordance with Table 606.4. For insulation outside of the conductivity ranges specified in Table 606.4, the minimum thickness of the insulation shall be determined in accordance with Equation 6-4. T = r [(1 + t/r)K/k

1] (Equation 6-4)

Where: T = minimum insulation thickness (inches). r = actual outside radius of pipe (inches) t = insulation thickness specified in Table 606.4 for applicable fluid temperature and pipe size. K = Conductivity of alternate material at mean temperature indicated for the applicable fluid temperature (Btu x in/h x ft

2 x

oF)

k = the upper value of the conductivity range specified in Table 606.4 for the applicable fluid temperature. Building cavities and interstitial framing spaces shall be large enough to accommodate the combined diameter of the pipe plus the insulation, plus the full thickness of the insulation plus any other objects in the cavity that the piping must cross.

Exception: Piping insulation is not required for the following:

1. Factory-installed piping within HVAC equipment tested and rated in accordance with Section 606.2.

2. Piping conveying fluids having a design operating temperature range between 60F and

105F. 3. Piping conveying fluids not heated or cooled such as roof and condensate drains, cold water supply, and natural gas piping. 4. Where heat gain or heat loss will not increase energy usage such as liquid refrigerant piping. 5. Piping having an outside diameter or 1 inch or less, associated with strainers, control valves, and balancing valves.

TABLE 606.4 MINIMUM PIPE INSULATION THICKNESSa, b

Fluid Conductivity Btu-in./(h-ft2-F) Ratio of Wall Thickness of Pipe Insulation to Nominal Pipe Diameter

Steam 0.27 – 0.34 ≥ 2:1

Hot Water 0.22 – 0.29 ≥ 1:1

Chilled Water 0.22 – 0.28 ≥ 1:1 a. The proportions apply to all nominal pipe diameters greater than ¼ inch and less than or equal to inches. For nominal pipe

diameters larger than 2 inches, outside diameter, the minimum wall thickness of the insulation shall be equal to the wall thickness required for 2 inch pipe. b. These thicknesses are based on energy efficiency considerations only.


Reason: ’Two of the footnotes to Table 606.4 are actually regulation – specifically footnotes a and c. In addition, the right hand column of Table 606.4 is unclear as a result of the combination of the column title and how the limits are expressed. The proposed reformat moves Footnote a into the beginning of the existing paragraph. It lets the code user know up front that the section only applies if the piping is over ¼ inch as opposed to waiting to find this key exception in a footnote. Footnote c is also moved to the midst of the original first paragraph . The requirement is piping insulation. At first blush the requirement is simplified by a reference to the table, however the table establishes the requirements for only a certain range of conditions. The balance of the conditions is specified by the formula. This is the requirement and should not be buried in a footnote. The change to the 3

rd column clarifies that

the regulated thickness is a ratio of the pipe and insulation diameters.

Description: Format based on PV1.0 and 2.0 606.4 Heating, ventilation and air conditioning (HVAC) piping insulation. Piping, including valves, fittings and piping system components, in heating, ventilation and air conditioning (HVAC) systems shall be thermally insulated in accordance with Table 606.4. Building cavities and interstitial framing spaces shall be large enough to accommodate the combined diameter of the pipe plus the insulation, plus the full thickness of the insulation plus any other objects in the cavity that the piping must cross.

Exception: Piping insulation is not required for the following:

1. Factory-installed piping within HVAC equipment tested and rated in accordance with Section 606.2.

2. Piping conveying fluids having a design operating temperature range between 60F and

105F. 3. Piping conveying fluids not heated or cooled such as roof and condensate drains, cold water supply, and natural gas piping. 4. Where heat gain or heat loss will not increase energy usage such as liquid refrigerant piping. 5. Piping having an outside diameter or 1 inch or less, associated with strainers, control valves, and balancing valves.

Hot Water 0.22 – 0.29 At least the Same

Chilled Water 0.22 – 0.28 At least the Same a. Piping with a nominal diameter larger than ¼ inch shall be insulated. b. The proportions in this column apply to all nominal pipe diameters greater than ¼ inch and less than or equal to 2 inches. For nominal pipe diameters larger than 2 inches, outside diameter, the minimum wall thickness of the insulation shall be equal to the wall thickness required for 2 inch pipe. c. For insulation outside the stated conductivity range, the minimum thickness shall be determined as follows: T = r[(1 + t/r)K/k – 1].

Where: T = minimum insulation thickness inches. r = actual outside radius of pipe inches. t = insulation thickness listed in the table for applicable fluid temperature and pipe size. K = conductivity of alternate material at mean rating temperature indicated for the applicable fluid temperature (Btu·in./h·ft

2 x °F)

k = the upper value of the conductivity range listed in the table for the applicable fluid temperature.

d. These thicknesses are based on energy efficiency considerations only.


CCC-IgCC-8-11 CODE SECTION(S) # 606.5 (formerly 607.6) Reference Code Changes: None – Original format in PV1.0 and 2.0 Proposed reformat – Section 606.5 recommended final version. 606.5 Economizers. Economizers shall comply with the requirements of the International Energy Conservation Code, except as noted herein. 606.5.1 Air Economizer systems. Each cooling system that has a fan shall include either an air economizer complying with Section 606.5.1.1 or a water economizer complying with Section 606.5.1.2.

Exception: Economizers are not required for the following.

1. In climate zones other than 1A and 1B, individual fan-cooling units with a supply capacity less than 33,000 Btu/h, provided the total capacity of all systems without economizers within a building shall not exceed 480,000 Btu/h, nor 20 percent of the building’s air economizer capacity, whichever is greater.

(No change to exceptions 2 through 6)

Delete Table 606.5.1(1). Reason: Table 606.5.1(1) is referenced only in Exception #1 to Section 606.5.1. Contrary to the title of the table, it doesn’t establish economizer requirements, but in fact exempts certain systems from providing economizers and via the footnote sets a limit to the exception. The table, if left as is, will be misused by people looking for a quick answer regarding economizer requirements. The proposed format replaces an ‘elaborate’ table with a simple sentence a little over 3 lines long.

Description: Format based on PV1.0 and 2.0 606.5 Economizers. Economizers shall meet the requirements of the International Energy Conservation Code, except as noted herein. 606.5.1 Air Economizer systems. Each cooling system that has a fan shall include either an air or water economizer meeting the requirements of Section 606.5.1.1 or 606.5.1.2, respectively. Exception: Economizers are not required for the following. 1. Individual fan-cooling units with a supply capacity less than the minimum listed in Table 606.5.1(1).

2. In Group I-2, Hospitals, and Group B, Ambulatory care facilities, where more than 75 percent of the air designed to be supplied by the system is to spaces that are required to be humidified above 35° F (__

o C) dew-point temperature to comply with applicable codes or

accreditation standards. In all other occupancies, where more than 25 percent of the air designed to be supplied by the system is to spaces that are designed to be humidified above 35°F (

oC) dew-point temperature to satisfy process needs.

3. Systems that include a condenser heat recovery system that is designed to utilize sixty percent of the peak heat rejection load at design conditions and there is a documented need for that rejected heat for either service hot water or space heating during peak heat rejection design conditions.

4. Systems that serve spaces estimated as having a sensible cooling load at design conditions, excluding transmission and infiltration loads, of less than or equal to transmission and


infiltration losses at the temperature and relative humidity design conditions in accordance with Section 6.1 of ASHRAE 55.

5. Where the use of outdoor air for cooling will affect supermarket open refrigerated casework systems.

6. Where the cooling efficiency meets or exceeds the efficiency improvement requirements in Table 606.5.1(2).

b. Setpoint “A” corresponds to a curve on the psychometric chart that goes through a point at approximately 75°F and 40 percent relative humidity and is nearly parallel to dry-bulb lines at low humidity levels and nearly parallel to enthalpy lines at high humidity levels.

Proposal: Delete footnotes a and b to Table 606.5.1.1.3(2) Reason: Footnote ‘a’ provides a requirement which is unclear and therefore will likely not be enforced. There is no definition of ‘substantially different that sea level’. For someone in Florida, that could mean 200 feet; for someone in Colorado it could mean 9000 feet. The second part of the footnote is an example, something that would be suited for the Commentary, were the requirement clear. Footnote ‘b’ appears to be either a definition or descriptor of Setpoint A. It doesn’t provide any regulation or clarity to the requirement provided in the table.


CCC-IgCC-10-11 CODE SECTION 606.9 [formerly 607.10] Reference Code Changes: GEW192 and 194 (and Original format in PV1.0 and 2.0) Description:

Section 608.2 and 608.2.1 were revised as follows by GEW192 and 194 608.2 Sleeping unit controls. Sleeping units in hotels, motels, boarding houses or similar buildings Group R-1 and R-2 occupancies shall have an automatic control system or device that for detecting occupancy to shut shuts off all permanently wired luminaires and switched receptacles, except those in bathrooms, when the unit is not occupied within 30 minutes of the unit being vacated. GEW 192, GEW194

Exception: Sleeping unit controls are not required in sleeping units where all permanently wired luminaires and switched receptacles, except those in bathrooms, are connected to a captive key control, lighting and switched receptacles are controlled by an occupant sensor that requires manual intervention to energize circuits. (GEW192-11)

608.2.1 Sleeping unit bathroom controls. All permanently wired luminaires located in bathrooms within sleeping units in hotels, motels, boarding houses or similar buildings Group R-1 and R-2 ocupancies shall be equipped with occupant sensors that require manual intervention to energize circuits. GEW194

Exception: Up to 5 watts of lighting in each bathroom shall be permitted to be connected to the captive key control at the main room entry instead of being connected to the occupant sensor control.

Section 606.9 as it appears in PV2.0 – was not subject to a code change in 2011. 606.9 Control of HVAC in hotel/motel guest rooms. A dedicated system to automatically control HVAC system energy shall be installed to control guest room HVAC energy consumption during unoccupied periods. Such controls shall be designed to raise cooling and lower heating temperature set points by at least 4 ºF (-2 ºC) during unoccupied periods.

Exception: Automatic control are not required in Group R-1 occupancy, hotels and motels, with fewer than 20 guest rooms.

Proposal: Revise 606.9 as follows: 606.9 Control of HVAC in Group R-1 sleeping units. In Group R-1 occupancies each sleeping unit shall be provided with a dedicated system to automatically control the heating ventilation and air-conditioning (HVAC) systems to control the energy consumption during occupied periods. The controls shall be designed to raise cooling and lower heating temperature set points by at least 4 ºF (2 ºC) during period when the sleeping unit is unoccupied.

Exception: Automatic controls are not required in Group R-1 occupancies with fewer than 20 sleeping units.

Reason: There are 2 changes incorporated in the proposed revision to 606.9. The first is bring in the occupancy designation from the IBC that applies to hotels and motels. This is in part the change which was approved for Section 608.2. The proposal is to only refer to Group R-1 because the text in 606.9 only refers to hotels and motels. This is distinct from the text that was replaced in 608.2 which extended beyond the Group R-1 occupancy.


The second change is to update the term ‘guest room’ to the defined term ‘sleeping unit’. Guest room is no longer used in the IBC, but instead the ‘guest rooms’ of a hotel are defined as ‘sleeping units’. This is clearer in providing specific limits and requirements in the building code. Changing 606.9 allows parallel construction of the regulation with 608.2 and the IBC. There may be some remaining use of ‘guest room’ in the IECC. A check of the IECC index for ‘guest room’ says ‘See sleeping unit’’


CCC-IgCC-11-11 CODE SECTION(S) # 607.5 Reference Code Changes: Original text in PV1.0 Description: 607.5 Waste water heat recovery system. The following building types shall be provided with a waste water heat recovery system that will preheat the incoming water used for hot water functions by not less than 10 ºF (5.6 C):

1. Group A-2, restaurants and banquet halls; 2. Group F, laundries; 3. Group R-1, boarding houses (transient), hotels (transient), motels (transient); 4. Group R-2 buildings; and 5. Group A-3, health clubs and spas 6. Group I-2, hospitals, psychiatric hospitals and nursing homes.

Exception: Waste heat recovery systems are not required for single-story, slab-on grade and single-story, on crawl-space buildings.

Reason: The exception is an incomplete sentence. It doesn’t state what is the specific exception. With specific background information, the safest assumption is that the exception is to the whole requirement. The added words simply clarify the intent of the exception.


CCC-IgCC-12-11 CODE SECTION 610.2 [formerly 611.2] Reference Code Changes: No change in 2011 - Format in PV 2.0 Description: 610.1 Renewable energy systems requirements. Buildings that consume energy shall comply with Sections 610.1 through 610.4. Each building or surrounding lot or building site where there are multiple buildings on the building site shall be equipped with one or more renewable energy systems in accordance with this Sections 610.1 through 610.4 Renewable energy systems shall meet the requirements of Section 610.2 for solar photovoltaic systems, Section 610.3 for wind systems, or Section 610.4 for solar water heating systems, and Section 610.5 for performance monitoring and metering of these systems as approved by the code official. These systems shall be commissioned according to the requirements of Section 611. Exceptions not shown

610.2 Solar photovoltaic systems. Solar photovoltaic systems shall be designed, constructed and sized to provide not less than two percent of the total estimated annual electric energy consumption of the building, or collective buildings on the building site in accordance with Section 610.1.1 or 610.1.2. Exception: 610.2.1 Limitation. Solar photovoltaic systems are not permitted to be used to comply with Section 610.1 where building sites with total global insolation levels lower than 2.00 kWh/m2/day as calculated in accordance with NREL SERI TR-642-761. Reason: The ‘exception’ to Section 610.2 should not be indicated as an exception because it isn’t a lessoning or waiver of a requirement. In fact it is a limitation (prohibition) on the use of photovoltaic systems. The proposed change simply gives this provision its own section number and title.


CCC-IgCC-13-11 CODE SECTION(S) # 702.1.2, 702.1.3 Reference Code Changes: GEW304-11 Description:

Delete without substitution: 702.1.2 Additional reductions. The provisions for Tier 1 and Tier 2 maximum fixture flow rates shall be applicable where indicated in Table 302.1. The specific requirements for Tier 1 and Tier 2 fixture and fitting consumption shall be as follows: Tier 1. A schedule of plumbing fixtures and fixture fittings shall be provided that demonstrates that fixture and fitting consumption meets the applicable reduced flow rates specified in Table 702.1 and that demonstrates a 30 percent reduction in the reference aggregate fixture and fitting potable water consumption calculated in accordance with Section 702.1.1. Tier 2. A schedule of plumbing fixtures and fixture fittings shall be provided that demonstrates that fixture and fitting consumption meets the applicable reduced flow rates specified in Table 702.1 and that demonstrates a 40 percent reduction in the reference aggregate fixture and fitting potable water consumption calculated in accordance with Section 702.1.1. 702.1.3 Reduction prohibited. The flow rates for emergency and decontamination fixtures and fittings shall not be reduced below the specifications of ANSI/ISEA Z358.1.

Reason: GEW 304 eliminated Tables 702.1(1) and 702.1.1(2) and Section 702.1.1 (see attached for reference). The result of that action is that there is no longer a method to establish a baseline for water usage per day so that a calculation for reduced water usage per day can be made to determine if the reduced water usage is 30 percent (or 40 percent) less than the baseline. In order words, there is no longer a method to demonstrate compliance with Tier 1 and Tier 2 water reductions. Therefore, Sections 702.1.2 and 702.1.3 no longer make sense and needs to be deleted from the code. In retrospect, the proponent should have included Sections 702,1,2 and 702.1.3 for deletion along with the other sections and table.


GEW304-11 702.1, Table 702.1, 702.1.1, Table 702.1.1(1), Table 702.1.1(2)

Proposed Change as Submitted Proponent: H. W. (Bill) Hoffman, representing H. W. (Bill) Hoffman & Associates, LLC ([email protected]) Revise as follows: 702.1 Fitting and fixture consumption. Fixtures shall comply with Table 702.1. A schedule of plumbing fixtures and fixture fittings shall be provided that demonstrates compliance with all of the following:

1. The maximum water consumption of fixtures and fittings shall comply with the flow rates specified in Table 702.1 for the fixtures and fittings listed therein.

2. The aggregate potable water consumption of fixtures and fittings shall be at least 20 percent less than the reference value calculated in accordance with Section 702.1.1.

Exceptions: The following fixtures and devices shall not be required to comply with the reduced flow rates of this section.

1. Blowout design water closets having a maximum water consumption of 2.8 gallons (10.4

L) per flush. 2. Clinical sinks having a maximum water consumption of 4.5 gallons (17 L) per flush. 3. Service sinks, bath valves, pot fillers, laboratory faucets, utility faucets, and other fittings

designed primarily for filling operations.

702.1.1 Aggregate fixture and fitting water consumption calculation. The aggregate consumption of all fixtures and fittings shall be calculated in accordance with Tables 702.1.1(1) and 702.1.1(2) for the purpose of demonstrating compliance with the aggregate consumption requirement in Sections 702.1 and 702.1.2. Table 702.1.1(1) is to be used first to calculate the reference water use and Table 702.1.1(2) is then to be used to calculate the required reduction in that reference water use. The percentage of reduction of the total water use shall be calculated in accordance with equation 7-1. Consumption for each fixture or fitting type = (flow rate) x (duration) x (daily uses per occupant) x (number of occupants). The aggregate fixture and fitting consumption is equal to the sum of the consumption values for each fixture and fitting located in the occupancy. Percent reduction = [(R-D)/R] x 100 (Equation 7-1) Where: R = Total reference water use determined from Table 702.1.1(1) D = Total design water use determined from Table 702.1.1(2) (Renumber subsequent section)

Table 702.1.1(1)

MAXIMUM FIXTURE AND FITTING FLOW RATES FOR REDUCED WATER CONSUMPTION

Table 702.1.1(2)

REFERENCE FIXTURE AND SUPPLY FITTING WATER CONSUMPTION To Calculate Baseline Water Use Projections

Reason: The calculation procedure is complicated and may not be used. Code people can make use of a table much easier and more accurately. The flow rate for private faucets was changed to 1.0 gpf. That is more than enough for hand washing, shaving, etc. Several studies have shown that people seldom turn the faucet in their bathroom on more than 1.0 gpm to 1.5 gpm. Cost Impact: The code change proposal will not increase the cost of construction.

CCC-IgCC-14-11 CODE SECTION(S) # 702.6.3 Reference Code Changes: GEW 232-11, GEW 321-11 Description: Revise as follows: 702.6.3 Food steamers. Food steamers shall consume not more than 2.0 gal (7.5 L) per hour in the full operational mode. than the amounts indicated in Table 610.2.3. Reason: Successful final action on GEW 232-11 put water usage limitations for food steamers in a Table in Chapter 6 of the code. The water usage limitations for this same equipment found in Chapter 7 is in conflict with those requirements. The proponent of GEW 232 tried to resolve this conflict with a public comment to proposal GEW 321. However, he failed to get to the mike and put this public comment into play. To resolve this conflict, it is suggested that Section 702.6.3 simply reference the new table so that there is only one location in the code for water usage limitations for this equipment. See attached reference material.

GEW232-11 610.2.3

Proposed Change as Submitted Proponent: Dipak J. Negandhi P.E, representing ASTM Committee F26 on Food Service Equipment Revise as follows: 610.2.3 Commercial food service equipment. Not less than 50 percent of the aggregate rated power allocated to ENERGY STAR-eligible commercial food service equipment shall be ENERGY STAR-eligible qualified based on aggregate rated power. food service equipment including, but not limited to, open deep-fat fryers, hot food holding cabinets, reach-in refrigerators and freezers, solid door refrigerators and freezers defined by ENERGY STAR. Steam cookers, dishwashers, griddles, and convection gas and electric ovens, shall be ENERGY STAR qualified. Reason: 1. EPA utilizes the term ENERGY STAR “qualified”, 2. This wording aligns the IGCC code with both the intent and requirements of the US Green Building Council’s LEED 2009 for

Retail criteria as quoted here:” Install ENERGY STAR–qualified equipment for 50% (by rated power) of ENERGY STAR–eligible equipment installed as part of the tenant s scope of work. This requirement includes appliances, office equipment, electronics, and commercial food service equipment.” Reference: LEED 2009 for Retail: Commercial Interiors, EA Prerequisite 2: Minimum Energy Performance, Page 14, Member Approved March 2010.

3. There are many categories of commercial food service products where EPA has not yet developed qualification criteria for some specific model variations and for facilities that cook for large groups. These are large institutions such as hospitals, military installations and school cafeterias The code, as currently worded will preclude such facilities from complying with this section of the code.

4. One example is commercial dishwashers. There are essentially three types of conveyor dishwashers; single tank rack type, multiple tank rack type and rackless conveyor. Although single and multiple tank rack conveyor machines are ENERGY STAR qualified, EPA has not yet established certification criteria for rackless conveyor dishwashers. These machines are common in larger, institutional facilities such as hospitals and school cafeterias. Many of these large models include energy recovery systems and use very little resources per dishes washed.

5. Similar situation exists for other commercial food service equipment such as large deep fat fryers, steam cookers, ovens and hot food holding cabinets.


6. In the absence of qualification statement as recommended above, customers may be inclined to use two or more smaller equipment with an ENERGY STAR rating rather than one larger model. The net result would be higher energy and water consumption, crowded kitchens and inefficient operations

7. Properly defined specifications which are complimentary to other standards that attempt to utilize energy and water efficiently – such as USGBC’s LEED, will permit a greater number of installations where capacity based equipment can be specified for the application (i.e. meet the facility demand for cooking loads) and complement IgCC’s goal to efficiently utilize energy and water resources.

Cost Impact: The code change proposal will not increase the cost of construction. In some instances it may permit economies of scale in both initial cost and operating costs.

610.2.3-NEGANDHI.doc

Public Hearing Results Committee Action: Approved as Modified Modify the proposal as follows: 610.2.3 Commercial food service equipment. Not less than 50 percent of the ENERGY STAR-eligible commercial food service equipment shall be ENERGY STAR qualified based on aggregate rated power energy input rating. Committee Reason: The committee approved the proposed code change as modified because the ENERGY STAR commercial food service equipment should have properly defined specifications to utilize energy and water efficiently. The modification was that the equipment shall be ENERGY STAR qualified based on aggregate rated energy input rating.

Assembly Action: None

Individual Consideration Agenda

This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Dipak J. Negandhi, PE, Unified Brands Inc./Groen, representing ASTM Committee F26 on Food Service Equipment, requests Approval as Modified by this Public Comment Modify the proposal as follows: 610.2.3 Commercial food service equipment. Not less than 50 percent of the ENERGY STAR eligible commercial food service equipment installed shall be ENERGY STAR qualified comply with energy efficiency and water use as identified on Table 610.2.3, based on aggregate energy input rating.

A factory-made assembly consisting of a condensing unit and ice-making section operating as an integrated unit, with means for making and harvesting ice and combines the ice-making mechanism and storage compartment are into an integral cabinet. Oven, Convection. A chamber designed for heating, roasting, or baking food by conduction, convection, radiation, and/or electromagnetic energy. Refrigerator. Equipment designed to enclose a space of mechanically cooled and temperature-controlled air used to maintain prescribed cold food holding temperatures. Steam Cooker. Equipment in which potable steam is used for heating, cooking, and reconstituting food.


Commenter’s Reason: 1. During the public hearing phase the Code Committee requested ASTM F26 to recommend efficiency levels for different types

of food equipment so as not to unduly burden efficient operation of a commercial kitchen but at the same time comply with the key purpose of IgCC.

2. While use of Energy Star qualified equipment is commendable, it entails risks that Energy Star standards and values are subject to change at any time based on other criteria. Thus a specific model that is Energy Star Qualified today may not be a Qualified model next year. This situation in turn creates confusion with users and Code officials with regards to compliance – should the Qualification apply to model specified during design of kitchen, at the time of placing PO or at the time of installation.

3. The use of a single table that comprehensively lists efficiency and water use ratings for all types of commercial food service equipment (and their definitions) facilitates simplicity for specifying engineer, buyer and code officials during evaluations.

4. All efficiency and water use values in the table are per acceptable standards written by internationally accepted bodies such as ASTM, ASHRAE and AHRI.

5. The equipment definitions may be added to ‘definitions’ section of the code if preferred. Analysis: The standards other than ASTM referenced, were not reviewed or considered by the ICC Code Development committee and it was not considered by the hearing attendees at the time of the code development hearings. Section 3.6.3.1 of Council Policy #28, Code Development, requires that new standards be introduced in the original code change proposal, therefore, the introduction of a new standard via a public comment is not in accordance with the process required by CP# 28 for adding new standards to the code.

CCC-IgCC-15-11 CODE SECTION(S) # ___803.1.3______ Reference Code Changes: GG516 and PC for same Description: Code change GG516-11 attempted to increase the air filter efficiency during the building construction phase to 11 from the current 8. The only public comment passed and simply added a reference to a filter testing standard. No attempt to change the filter efficiency was attempted or discussed at the final action hearings. The problem is that the public comment was not correctly published to carry over the change from 8 to 11. The PC should have shown the efficiency rating as 11, not 8, because the PC was only attempting to modify the original proposal by adding the testing standard reference. The PC was not attempting to strike the 11 and replace it with 8. In error, the PC was published with the original 8 with no legislative format to indicate that the 8 was being restored. This error was not published or discussed at the hearings. There are two possible scenarios:

1) The voters for the PC saw the 8 and assumed that the PC was trying to restore the 8, notwithstanding the fact that the 8 was not underlined and there was no 11.

2) The voters focused only on the intent of the PC and ignored the incorrect 8, or realized that it was supposed to be an 11.

It is staff’s opinion that the error in publishing should not have the effect of cancelling the purpose of the original proposal, therefore scenario 2) should be reflected in the 2012 edition of the code. Reason: If the PC had been shown correctly, the final results of approving the PC would have been text requiring a rating of 11. The PC only attempted to modify the original proposal by adding the standard and there was no intent to change what should have been an 11. Based on how ICC publishes Public Comments that modify code change proposals, the approval of the PC indicates that the filter efficiency should be 11. On the other hand, it is merely conjecture to assume that the voters assumed that the PC did more than the proponent intended and indicated in his reason and testimony.

GG516-11 803.1.3

Proposed Change as Submitted Proponent: Kathleen M. Petrie, representing City of Seattle’s Department of Planning and Development ([email protected]) Revise as follows: 803.1.3 Construction phase ductless system or filter. Where spaces are conditioned during the construction phase, space conditioning systems shall be of the ductless variety, or filters for ducted systems shall be rated at MERV 8 11 or higher and system equipment shall be designed to be compatible. Duct system design shall account for pressure drop across the filter. Reason: During the construction phase, filters for ducted systems in conditioned spaces should be increased from a MERV 8 to a MERV 11. Unlike MERV 8 filters, MERV 11 rated filters have the ability to capture lead particulates, which is particularly important during alteration projects when materials with lead may become exposed and disturbed. Using a higher rated filter will help to maintain good indoor air quality for individuals constructing the building. Cost Impact: The code change proposal will increase the cost of construction

803.1.3-PETRIE


Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Steve Ferguson, The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), requests Approval as Modified by this Public Comment. Modify the proposal as follows: 803.1.3 Construction phase ductless system or filter. Where spaces are conditioned during the construction phase, space conditioning systems shall be of the ductless variety, or filters for ducted systems shall be rated at MERV 8 or higher in accordance with ASHRAE 52.2, and system equipment shall be designed to be compatible. Duct system design shall account for pressure drop across the filter. Commenter’s Reason: There is currently no test method for determining MERV in the code. ANSI/ASHRAE Standard 52.2-2007 Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size is the correct reference for this application. Analysis: The standard, ASHRAE 52.2, was not reviewed or considered by the International Green Code Council – General Development committee and it was not considered by the hearing attendees at the time of the code development hearings. Section 3.6.3.1 of Council Policy #28, Code Development, requires that new standards be introduced in the original code change proposal, therefore, the introduction of a new standard via a public comment is not in accordance with the process required by CP# 28 for adding new standards to the code.

Description: Coordination of proposed changes to Table 302.1 with Sections 1007.2 through 1007.2.3.2, formerly Sections 1006.4 through 1006.4.3.2. GEW 297 was approved as submitted at the final action hearings in Phoenix. This proposal deleted all references to Section 1007.2, formerly Section 1006.4, from Table 302.1. The question is whether the deletion of Section 1007.2, formerly Section 1006.4, from Table 302.1 a) is editorial and should be honored, or b) should not be made.

(Portions of table not shown, remain unchanged) REASON: The proponents reason statement indicated that the changes contained in GG297 were editorial, to coordinate with other code change proposals submitted by the proponent. The proposed change to delete Section 1007.2, formerly Section 1006.4, from Table 302.1 would have been editorial if another change by the same proponent, GG743, had been approved. GG743 proposed to delete the text of former Sections 1007.2 through 1007.2.3.2, formerly Sections 1006.4 through 1006.4.3.2, from the body of the code. GG743, however, was disapproved. Therefore, the portion of GG297 that addressed Section 1007.2, formerly Section 1006.4, is no longer editorial and the reference to it should remain in Table 302.1.

CCC-IgCC-17-11 TABLE 302.1 AND FORMER CODE SECTIONS 1006.4, 1006.4.1, 1006.4.2, 1006.4.3, 1006.4.3.1 AND 1006.4.3.2 Reference Code Change Proposals: GG246, GG744 AM, GG745 AMPC1, GG747 and GG748. Description: Coordination of proposed changes to Section 1006.1 (formerly Section 1006.2).


1006.1 Deconstruction and demolition material and waste management plan. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be deconstructed and diverted from landfills. A demolition or deconstruction material and waste management plan shall be developed that is in accordance with Section 503.1, that includes procedures for deconstruction, and that documents the total materials in buildings, structures and portions thereof to be deconstructed or demolished and the materials to be diverted. REASON: Discussed in this reason are only those portions of the referenced code change proposals and public comments which pertain to former Section 1006.1, formerly Section 1006.2.

GG246 renames the section, deletes the second sentence and then re-writes it, and adds 3 items. However, the 3 items added by GG246 are all contained in Section 503.1, formerly Section 502.1, which is referenced in both GG745 AMPC1 and GG748 AM, so they are not shown here and Section 503.1 is referenced instead as this was seen by staff as a cleaner option that inherently coordinates the requirements in these related sections. There were also other proposed changes to Section 503.1, formerly Section 502.1, which would have caused the coordination between it and Section 1006.1, formerly Section 1006.2, to diverge, but this scenario keeps them coordinated. GG744 AM moves former Section 1006.2 to become Section 1006.1 and renumbers other sections in Chapter 10. In addition to referencing Section 503.1, formerly Section 502.1, GG745 AMPC1 adds “deconstruction” to the title and adds a requirement to “include procedures for deconstruction.” GG747 deletes “and incineration.”

Following are the proposed code changes and public comments, as well as the version of Section 503.1, formerly Section 502.1, as it will appear in the 2012 IgCC.

GG246-11 (AS) Showing only those portions pertaining to Section 1006.1, formerly Section 1006.2. 1006.2 Demolition material waste management plan. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be diverted from landfills and incineration. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both. A demolition or deconstruction waste management plan shall be developed and shall include provisions that address all of the following:

1. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted shall be required.

2. The amount of total materials and materials to be diverted shall be specified and shall be calculated by weight or volume, but not both.

3. Receipts or other documentation related to diversion shall be maintained through the course of construction. When requested by the code official, evidence of diversion shall be provided.

Reason: Section 1006.2:

The section title has been modified to clarify that it specifically addresses demolition material and directive for a waste management plan. The proposed heading is consistent with sections 402.3.6 and 502.1.


Items 1 and 2 are a part of the requirements of the plan so we propose they be pulled out of the 1006.2 charging language and developed into specific independent items.

Item 3 has been added to provide direction as to what type of documentation will be acceptable in order to prove material diversion; this language is consistent with similar (proposed) items within sections 402.3.6 and 502.1.

GG744-11 (AM) Showing only those portions pertaining to Section 1006.1, formerly Section 1006.2. Revise as follows:

SECTION 1006 DEMOLITION

1006.1 Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be diverted from landfills and incineration. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both.

SECTION 1006 1008 JURISDICTIONAL REQUIREMENTS

1006.2 Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be diverted from landfills and incineration. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both. Reason: Section 1006 currently has a mixture of provisions that are always mandatory—Sections 1006.2 and 1006.3—and one “jurisdictional requirement” which only applies when the jurisdiction makes it mandatory in Table 302.1. This proposal separates the always-mandatory provisions into their own sections, similar to the sections in Chapter 10 for additions, alterations, etc.

GG745-11 (AMPC1) 1006.2

Proposed Change as Submitted Proponent: Susan Gitlin, representing US Environmental Protection Agency ([email protected]) Revise as follows: 1006.2 Deconstruction and Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be deconstructed and diverted from landfills and incineration. A Construction Material and Waste Management Plan in accordance with Section 502.1 shall be developed and implemented to recycle or salvage renovation and demolition waste. The Construction Material and Waste Management Plan shall describe the plan for deconstruction. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both. Reason: Waste from demolition and renovation comprises a significant majority of C&D waste. EPA estimates that in the U.S., 170 million tons – or approximately 3.2 pounds of building-related C&D materials per capita per day (pcd) – is disposed to a landfill. The majority of C&D waste, an estimated 155 million tons, is renovation and demolition waste. Including deconstruction in construction


waste management procedures will ensure that C&D materials will be reused or recycled with the minimum possible loss of functionality and value.

Diversion of construction materials from the waste stream specifically for recycling and reuse yields significant environmental benefits. In addition to the costs and environmental risks associated with disposal of materials (such as incineration of materials containing hazardous chemicals, and emissions from incinerators), recycling and reuse conserves raw materials, energy, and water associated with resource extraction and manufacturing.

Section 502.1 specifies requirements for a Construction Material and Waste Management Plan for waste generated in new construction. The proposed change to Section 1006.2 extends those requirements to renovation/demolition waste. A Construction Material and Waste Management Report will provide an effective mechanism for the code official to verify compliance with the waste diversion requirement. The technical requirement set in place in Section 1006.2 (i.e., 50 percent diversion of deconstructed or demolished materials) will have no practical impact if it is not actually implemented, and code officials will be unable to determine building projects’ compliance with those requirements without a means to review performance verification information. The proposed change will also improve consistency in interpreting and enforcing this section across jurisdictions, and will reduce the burden on the code official to gather sufficient information to verify compliance.

The types of documentation already required by Section 1006.2 (manifests, weight tickets, receipts, and invoices) can form the basis for much of the Construction Material and Waste Management Report. These items are routinely generated in the course of construction, and thus should pose little additional burden to project managers to collect and synthesize. Bibliography: U.S. EPA. Estimating 2003 Building Related Construction and Demolition Materials Amounts. March 2009. Available at: http://www.epa.gov/epawaste/conserve/rrr/imr/cdm/pubs/cd-meas.pdf Cost Impact: The code change proposal will not increase the cost of construction.

Public Hearing Results

Committee Action: Approved as Modified Modify the proposal as follows: 1006.2 Deconstruction and Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be deconstructed and diverted from landfills and incineration. A Construction Material and Waste Management Plan in accordance with Section 502.1 shall be developed and implemented to recycle or salvage renovation and demolition waste. The Construction Material and Waste Management Plan shall describe the plan for deconstruction. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both. Committee Reason: It is critical to add deconstruction, particularly in a green code. We are seeing more deconstruction, particularly in urban environments. The proposal was modified to delete the words “deconstructed and” to be consistent with prior committee action.

Assembly Action: None

Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Ric Cochrane, representing the National Trust for Historic Preservation ([email protected]); Maureen Traxler, representing the City of Seattle Department of Planning and Development ([email protected]); Steven R Winkel, FAIA, PE, representing the American Institute of Architects ([email protected]), requests Approval as Modified by this Public Comment. Modify the proposal as follows: 1006.1 Deconstruction and Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be diverted from landfills and incineration. A Construction Material and Waste Management Plan in accordance with Section 502.1 shall be developed and implemented to recycle or salvage renovation and demolition waste. The Construction Material and Waste Plan shall be developed and implemented in accordance with Section 502.1, including procedures for deconstruction. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both.


Commenter’s Reason: The revision to the demolition section 1006.1 is a composite of three slightly different modifications to the same section which were added to the code by the committee and then modified. The intent of this change is that it correlates and supersedes the slightly varying provisions of GG744-11, GG745-11 and GG748-11, all of which were approved as modified by the committee.

GG747-11 (AS)

1006.2

Proponent: Dru Meadows, representing theGreenTeam, Inc. ([email protected]) Revise as follows: 1006.2 Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be diverted from landfills and incineration. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both. Reason: The proposed change brings the requirements for waste management of demolition projects into conformance with requirements for waste management of new construction as specified in Section 502.1. Section 502.1 does not require diversion from incineration.

It is inappropriate and impractical to hold demolition projects to a higher standard than new construction. Waste diversion on demolition projects is more likely to utilize incineration. Such projects often result in mixed waste that is not acceptable to reuse or recycling facilities. Then, the only feasible diversion option is incineration.

GG748-11 1006.2 Proponent: John Woestman, Kellen Company, representing Modular Building Institute (MBI) ([email protected]) Revise as follows: 1006.2 Deconstruction and Demolition. Where buildings, structures or portions thereof are deconstructed or demolished, a minimum of 50 percent of materials shall be diverted from landfills and incineration. Documentation of the total materials in buildings, structures and portions thereof to be deconstructed or demolished and materials to be diverted, and evidence of diversion, shall be provided. Material quantities shall be indicated and calculated by weight or volume, but not by both. A Construction Material and Waste Management Plan shall be developed and implemented in accordance with Section 502.1 and shall indicate deconstruction procedures.

Reason: The IgCC defines deconstruction as “The process of taking a building or structure, or portion thereof, apart, piece-by-piece, with the intent of recycling or salvaging as many of the materials, products and components as possible.” Thus, deconstruction is the method by which an existing building or portions thereof are reclaimed. The proposed revision clarifies the requirement accordingly.

The proposed revision also modifies the title of 1006.2 to prioritize deconstruction. The demolition of buildings produces enormous amounts of debris that in most countries results in a significant portion of the total municipal waste stream. The US EPA has estimated that 92% of all construction-related waste produced annually in the US is the result of renovations and demolitions, and that this waste is upwards of 30% of all waste produced in the US. (DfD Seattle)

EPA estimates following for demolition waste generation factor: Residential – from approximately 80 to 127 lb/sq.ft. depending on foundation type Nonresidential – from 155 to 158 lb/sq.ft. rage of waste generated was from 36 to 358 lb/sq.ft.

2. Materials to be diverted from disposal by efficient usage, recycling, reuse on the project,

manufacturer’s reclamation or salvage for future use, donation or sale shall be specified. 3. The amount percent of materials to be diverted shall be specified and shall be calculated by

weight or volume, but not both.

4. Receipts or other documentation related to diversion shall be maintained through the course of construction. Where requested by the code official, evidence of diversion shall be provided.

For the purposes of this section, construction materials and waste shall include all materials delivered to the site and intended for installation prior to the issuance of the certificate of occupancy, including related packaging. For the purpose of this section, Construction and waste materials shall not include land clearing debris, excavated soils and fill and base materials such as, but not limited to, topsoil, sand and gravel. Land-clearing debris shall include trees, stumps, rocks, and vegetation. Excavated soil, fill material and land-clearing debris shall be managed in accordance with Section 406.1.
