code committee is scheduled to meet following the board meeting today and then

in two weeks. The committee will complete its work using the 2015 IRC as the

base model code with Oregon amendments. Chief Turner said the committee will

address Chapter 3 in the meeting today.

Warren Jackson, code specialist, was introduced as the newest member to the

structural program. He comes to Building Codes Division with great

administrative and code knowledge.

IV. Communications - None

V. Appeals - None

VI. Unfinished business - None

VII. New business

A. Review proposed rules to clarify the difference between a recreational vehicle

from a wood-sided structure commonly called tiny house and park trailer.

This agenda item will impact manufactures and local government

Richard Baumann, policy analyst, Policy and Technical Services, said the

division’s Enforcement Services Section reviewed regulatory areas with certain

manufacturers of wood-sided, residential-type structures referred to in this agenda

item.

Mr. Baumann said the division is proposing amendments to the recreational

vehicle regulations. He said a temporary rule is included in the board packet the

division plans to enact after receiving feedback from the Residential and

Manufactured Structures Board and the public. The rule clarifies the definition of

RV’s and eliminates the park trailer code in Oregon. Because this matter is not the

adoption of a dwelling code, the division is seeking board input but does not need

a formal vote for approval or disapproval. The division will update the board once

the temporary and permanent rule making is complete.

Mark Long, administrator, Building Codes Division, said during division

investigation, three areas were of focus:

Licensing

Codes and standards

Permits and inspections

Administrator Long said that licensed electricians and licensed plumbers are

required for any type of built structure in Oregon. He stated that recreational

vehicles are defined in statute to be used temporarily, for recreational, seasonal, or

emergency purposes.

Nathan Watson, co-owner of Tiny SMART House, said that if tiny house

manufacturers in Oregon cannot build to the same code that the rest of the country

is building to, then consumers and manufacturers will take their business out of

state. He also said that in his opinion these rule changes are going to create a

major problem in Oregon when consumers do not have an avenue to legally build

a tiny house as an RV.

of 6

Todd Miller, Oregon Cottage Company, said he has always told his customers and

has advertised that whatever you can do with an RV is what you can do with one

of the tiny houses built and purchased from him. He has had multiple cottages

inspected and approved. Mr. Miller also told his clients they would need to

contact local jurisdiction for proper requirements. He said that for the last eight

years, he has been building and constructing tiny houses for multiple clients to

permanent residential classification.

Mr. Miller said that in January 2017 Brian Lamb, RV inspector for the division,

told him that the cottages being built as RV’s were no longer going to be

inspected as RVs.

Tor Stuart, co-owner Tiny SMART House, said that RVs and tiny houses are one

in the same. He said that the look of these structures is an irrelevant factor to the

use. He asked that the division be patient while this industry adapts to a new code

and regulations.

Administrator Long said the code has not changed. There is a lot of confusion

around the Oregon sticker. He reminded the board that the sticker is offered only

for structures that are for rent, lease, or sale. If the structure is permanent, the

residential code should be followed. If the structure is for temporary use, than the

Oregon sticker will apply and local jurisdictions should be contacted.

Administrator Long said by eliminating that requirement, the process will become

more seamless.

Although written warning has been sent out to those who may have potential

violations, the requirements will not be enforced until July 1, 2017.

Chair Lewis noted that Rich’s Portable Cabins Inc. has submitted written

testimony saying that the proposed changes are extremely broad, and are

devastating to the park model industry.

(Board took a 5-minute break. When members returned from break, the board went

directly into VII.B.)

B. Review and discuss December 2, 2016, Earth Advantage report “Cost

Analysis of Potential Energy Code Improvements” as it relates to residential

energy codes

Administrator Long explained that because the board must make a finding

regarding cost when it recommends approval of a particular code or

administrative rule, the board may choose to use the information contained with

the Earth Advantage report to address cost issues for energy-related code

proposals.

of 6

David Heslam, executive director, Earth Advantage, was connected by

teleconference and available to answer any questions related to the Earth

Advantage report included in the board packet, or the report titled Cost Analysis

of Potential Energy Code Improvements received by email Wednesday, January

11, 2017.

Mike Goodrich, chair of the 2017 Oregon Residential Specialty Code Committee,

said that the focus should be on affordability in Oregon and suggested that the

board continue to ask for a financial analysis.

Howard Asch, Oregon Home Builders Association, said that the cost of materials,

installation, and overhead, should be the only way to calculate the additional cost

that comes out of a code requirement. Currently lenders and appraisers do not

consider the facts of energy efficiency. Mr. Asch said that if the cost analysis

report proposal would have been submitted within the time allowed for

submittals, then those who submitted code proposals timely may have calculated

the cost analysis differently.

Emily Kemper said that it is time for Oregon to start pushing energy efficiency

codes.

Chair Lewis said she has been a custom builder and remodeler for 27 years. There

is not a lot of cost control on building materials. The cost of material is being

marketed nationwide/worldwide. After the recession the costs of sub-

contractors/labors have gone up. Although this item is focused on energy

efficiency, all cost components should be examined.

(John Chmelir disconnected from teleconference at 12:20 p.m.)

Members wanted to see an in-depth analysis completed on this report before

making any type of recommendation.

Administrator Long said he will send this item to the Construction Industry

Energy Board for its April 25 meeting, and send the cost analysis report to the

code committee to review for the energy provisions of the residential code. He

reminded the board of dates that need to be met for the code to be effective:

October 1, 2017, anticipated effective date of the 2017 ORSC

March or April of 2017 for this board to make a recommendation to the

Administrator

July 1, 2017, date anticipated for final code language to be ready so

printing will be complete by October 1, 2017

State of Oregon Board memo Building Codes Division May 10, 2017 To: Construction Industry Energy Board and Residential and Manufactured Structures Board From: Todd Smith, policy analyst, Policy and Technical Services Subject: Review of the Oregon Residential Specialty Code Change Committee’s Energy

Provision Recommendation Action requested: The ORSC Review Committee is providing the proposed residential energy provisions for the proposed 2017 Oregon Residential Specialty Code (ORSC) to the Construction Industry Energy Board and the Residential and Manufactured Structures Board for review. Background: The Oregon Residential Specialty Code Review Committee met eight times from November 30, 2016, to April 5, 2017. The recommendation from the committee included changes to the energy provisions of the ORSC. As part of the public code proposal process, the committee received two competing energy related proposals. The code review committee developed a compromise between these competing code proposals. There was also an additional energy related public proposal that makes a change to vertical door and pull down stair insulation requirements that was separate from the competing proposals and not part of the committee developed compromise. Both the committee developed compromise and the separate vertical door and pull down stair requirements have been included. Options for the Residential and Manufactured Structures Board: Approve the committee’s recommendation to adopt the proposed energy provisions and

forward to the Administrator for rulemaking and subsequent adoption, with the finding that the added cost, if any, is necessary to the health and safety of the occupants or the public or necessary to conserve scarce resources.

Agenda Item

VII.A.

of 2

a. As allowed in Section N1104.1, thermal performance of a component may be adjusted provided that overall heat loss does not exceed the total resulting from conformance to the required U-value factor standards. Calculations to document equivalent heat loss shall be performed using the procedure and approved U-values factors contained in Table N1104.1(1).

b. R-values used in this table are nominal, for the insulation only in standard wood framed construction and not for the entire assembly. c. Wall insulation requirements apply to all exterior wood framed, concrete or masonry walls that are above grade. This includes cripple

walls and rim joist areas. R-19 Advanced Frame or 2 x 4 wall with rigid insulation may be substituted if total nominal insulation R-value is 18.5 or greater. Nominal compliance with R-21 insulation and Intermediate Framing (N1104.5.2) with insulated headers.

d. The wall component shall be a minimum solid log or timber wall thickness of 3.5 inches (90 mm). e. Below-grade wood, concrete or masonry walls include all walls that are below grade and does not include those portions of such wall that

extend more than 24 inches above grade. R-21 for insulation in framed cavity; R-15 continuous insulation. f. Insulation levels for ceilings that have limited attic/rafter depth such as dormers, bay windows or similar architectural features totaling not

more than 150 square feet (13.9 m2) in area may be reduced to not less than R-21. When reduced, the cavity shall be filled (except for required ventilation spaces). R-49 insulation installed to minimum 6” depth at top plate at exterior of structure to achieve U-factor.

g. The maximum vaulted ceiling surface area shall not be greater than exceeding 50 percent of the total heated space floor area unless area has shall have a U-factor no greater than U-0.031 U-0.026 (equivalent to R-38 rafter or scissor truss with R-38 advanced framing). The U-factor of 0.042 is representative of a vaulted scissor truss. A 10-inch deep rafter vaulted ceiling with R-30 insulation is U-0.033 and complies with this requirement, not to exceed 50 percent of the total heated space floor area.

h. A = advanced frame construction, which shall provide full required insulating value to the outside of exterior walls. See Section N1104.6. i. Heated slab interior applies to concrete slab floors (both on and below grade) that incorporate a radiant heating system within the slab.

Insulation shall be installed underneath the entire slab. j. Sliding glass doors shall comply with window performance requirements. Windows exempt from testing in accordance with NF1111.2

Item 3 shall comply with window performance requirements if constructed with thermal break aluminum or wood, or vinyl, or fiberglass frames and double-pane glazing with low-emissivity coatings of 0.10 or less. Buildings designed to incorporate passive solar elements may include glazing with a U-factor greater than 0.35 by using Table N1104.1(1) to demonstrate equivalence to building envelope requirements.

k. Reduced window area may not be used as a trade-off criterion for thermal performance of any component. Exception: Table N1101.1(2), Envelope Measure 6: calculation allows baseline case 15% of total wall area as window when design case utilizes window area if less than 15%.

l. Skylight area installed at 2% or less of total heated space floor area shall be deemed to satisfy this requirement with vinyl, wood, or thermally broken aluminum frames and double-pane glazing with low-emissivity coatings. Skylight U-factor is tested in the 20 degree overhead plane per NFRC standards.

m. A maximum of 28 square feet (2.6 m2) of exterior door area per dwelling unit can have a U-factor of 0.54 or less. n. Glazing that is either double pane with low-e coating on one surface, or triple pane shall be deemed to comply with this U-0.40

requirement.

APPLICATION CRITERIA

Attach to this application written responses to the following questions. If needed, include in the response an explanation why a question does

not apply to your proposed code amendment. The division may reject an incomplete application. You must provide a thorough and complete

response to all questions, or your application may be considered incomplete.

Questions:

1. What does this code proposal

do? The proposal clarifies standards for insulation of vertical doors and pull-down stairs from

conditioned to unconditioned spaces by adopting a proposal the ICC codes committee

approved for the 2018 ICC code.

2. What problem in the code does

this proposal intend to address? The code is not presently clear whether vertical door insulation needs to comply as a door or as

an insulated wall. Pull-down stairs are not currently available with an insulation exceeding U-

0.10 or R-10 and are commonly modified in the field. Field modifications are often done in a

way that does not encourage insulation to be put back in place when the stair is used. This

assures some insulation will be in place.

3. Is the problem a fire or life safety matter? If so, explain. No.

4. Does the problem cause delays in the cost of construction

or inconsistency in application of the code? If so, how? Insulation values for vertical doors are open for varying interpretations.

Building officials may approach a field modified pull-down stair in

different manners and this will bring uniformity of interpretations.

5. How does this proposal solve the problem? The proposal provides a clear requirement for vertical door and pull-

down stair insulation requirements.

6. Are there other alternatives to this proposal that solve the

problem? If so, why is this proposal the best solution? There are no other known alternatives

Proposed amendments to OAR 918-305-0100 Table 1-E regarding low-rise residential electrical provisions of the 2017 Oregon Electrical Speicalty Code

Oregon Amendments to the 2017edition of the National Fire Protection Association (NFPA) 70, National Electrical Code (NEC) for the 2017 Oregon Electrical Specialty Code.

For the purpose of identifying Oregon amendments to the NFPA 70, NEC – “OESC” followed by a code section denotes an Oregon amendment to that section of code. Amendments may either be

additions of code language developed by Oregon, or the deletion of NFPA 70, NEC code language. Language contained in the NFPA 70, NEC, not listed in this table has not been amended by Oregon.

OESC 90.4 Enforcement. (First paragraph, no change to model code). This Code is intended to be suitable for mandatory application by governmental bodies that exercise legal jurisdiction over electrical installations, including signaling and communications systems, and for use by insurance inspectors. The authority having jurisdiction for enforcement of the Code has the responsibility for making interpretations of the rules, for deciding on the approval of equipment and materials, and for granting the special permission contemplated in a number of the rules.

By special permission, the authority having jurisdiction may waive specific requirements in this Code or permit alternative methods where it is assured that equivalent objectives can be achieved by establishing and maintaining effective safety.

Requests for special permission shall be made in writing to the authority having jurisdiction. Special permission must be granted in writing by the authority having jurisdiction and shall be obtained prior to the start of the electrical installation. This Code may require new products, constructions, or materials that may not yet be available at the time the Code is adopted. In such event, the authority having jurisdiction may permit the use of the products, constructions, or materials that comply with the most recent previous edition of this Code adopted by the jurisdiction.

Where the 2017 NEC requires electrical products to be “listed” or “labeled”, the words “listed” or “labeled” shall have the same meaning as “certified electrical product” under ORS 479.530.
