meeting, and the December 9, 2013 telephone conference be accepted. Sheerin seconded. Motion passed (11-0-0).

5. Standard 170 Republication. Ninomura advised that the 2013 edition has been published,

and thanked the committee for their hard work. Rousseau explained that two items have been issued in an Errata:

a. Reference to the 20013 Applications Handbook for air distribution device descriptions

was corrected back to the 2009 edition. The 2013 edition no longer includes the group types referenced by Standard 170.

b. Addendum l to the 2008 edition was comprised of the addition of 4 spaces to Table 7-1. This information was omitted from the 2013 edition.

ASHRAE SSPC 170

2.

Rousseau also indicated that, at FGI’s request, these two errata would be incorporated into the 2013 edition that is bound in the Guidelines.

6. FGI Update. Flannery noted that the Inpatient/Outpatient edition of the Guidelines was

expected to be published in February, with the Residential Guidelines following shortly thereafter.

7. Proposed Addendum ta, Package Rooftop Units. Ninomura presented a proposed

addendum (copy attached) to allow combustion air vents and outside air intakes for packaged gas-fired roof top air handling equipment to be allowed to have less than the required 25’ separation. A clarification (shown shaded) was suggested in the Clinical Sub-committee meeting to emphasize this reduction only pertains to the two points of a specific piece of equipment, not to intake or discharge points of adjacent pieces of equipment. This clarification was included in Ninomura’s proposed addendum.

a. Motion: Ninomura moved, and Rousseau seconded, that this change be issued in an

addendum for public review. Vote: Approved 11-0-0. Note: Voting members understood that these votes were for public review and, if no comments or only supportive comments were received, subsequent publication.

8. Clinical Sub-committee: Rousseau provided an overview of the previous day’s sub-

committee meeting. 9. Laboratory Ventilation: Sharp proposed that issues of laboratory ventilation be deferred to

ANSI Standard Z9.5. Specifically, he recommended the deletion of the laboratory spaces in Table 7-1. He indicated that the information contained therein is outdated and potentially dangerous. Flannery expressed a desire to have the information included in 170, so that Hospital Engineers did not have to try to obtain a copy of Z9.5. There was a discussion that research and clinical laboratories are different, and that the processes performed in clinical laboratories were more routine and constant, while research laboratories by definition perform processes with unknown results and varied chemicals. Sharp advised that in his experience, readers of Standard 170 applied the requirements of Table 7-1 to research facilities that may be located in health care facilities, thus the danger indicated above. The consensus of the committee was that the intent of Standard 170 was for it to only be applicable in clinical laboratories, and not to research laboratories located within health care facilities. The committee agreed the information should be updated and clarified, but should also remain in Standard 170.

ACTION: The HVAC Sub-committee will review and propose revised text.

10. Addendum tc, Reference Updates: Langowski presented an analysis of all references

included in the 2013 edition. After review of each reference, the committee generally agreed to the actions indicated in the attached annotated copy of Langowski’s analysis. One issue of filter testing remained unclear and will be addressed in a future addendum, if required.

a. Motion: Rousseau moved, and Sheerin seconded, that the changes discussed by the

committee, and recorded as Addendum tc (copy attached) be issued in an addendum for public review. Vote: Approved 12-0-0. Note: Voting members understood that these votes were for public review and, if no comments or only supportive comments were received, subsequent publication.

11. EHC Airborne Infectious Disease Presentation. Olmsted reported on a panel discussion

that occurred earlier in the day (A Comprehensive Look at Infections Disease and Air Filtration in Health Care Facilities: Energy Saving, IAQ Performance, and What Makes You Sick).

12. Change Proposal CP 170-13-12-0001/001. This change proposal was made to suggest that

Standard 170 refer to Standard 62.1 for various health care spaces. Ninomura presented a response (copy attached) and commentary that the proposal be rejected.

a. Motion: Rousseau moved, and Olmsted seconded, that this response and

commentary be accepted. Vote: Approved, 11-0-0. 13. Official Interpretation Requests - English. Sheerin presented recommended responses from

the HVAC Sub-committee:

a. Interpretation KP#3, regarding air change rates in Table 7-1– Sheerin presented a summary of the discussion within the HVAC sub-committee. English suggested that some type of IAQ criteria be included in the Standard vs. prescribed air change rates. The committee agreed to forward on a recommendation for research in this approach to TC 9.6. 1) Motion: Sheerin moved, and Gregory seconded, that the response to this

interpretation request be No, with commentary (copy attached). Vote: Approved, 11-0-0.

b. Interpretation KP#4, regarding simultaneous heating and cooling - after discussion

both in the Clinical sub-committee and the main committee meetings, the committee agreed with the HVAC sub-committee recommendation that the question should be addressed by SSPC 90.1. 1) Motion: Sheerin moved, and Olmsted seconded, that the response to this

interpretation request be No, with commentary (copy attached, as amended to indicate edition of Standard) 90.1. Vote: Approved, 11-0-0.

c. Interpretation KP#5, regarding ED and Radiology rooms - after discussion both in the

Clinical sub-committee and the main committee meetings, the committee agreed the interpretation was incorrect. Sharp opined that a better approach to ventilation of these waiting areas was possible and that Standard 170 give minimum requirements. Specifically, Sharp suggested that dilution in a space was a function of outside air, not air movement within the space. ACTION: The HVAC sub-committee will review this issue and propose alternatives at the next meeting.

1) Motion: Sheerin moved, and Platt seconded, that the response to this

interpretation request be No, with commentary (copy attached). Vote: Approved, 11-0-0.

14. Official Interpretation Request – Darwich. Sheerin presented a response to this

interpretation request regarding possible reduction in total air change rates in ORs based on usage of 100% outside air. Ninomura pointed out that OR air changes within the room were

4.

required to comply with the velocity requirement at the diffusers, regardless of the percentage of outside air included in the supply air.

a. Motion: Sheerin moved, and Gregory seconded, that the response to this

interpretation request be Yes, with commentary (copy attached). Vote: Approved, 11-0-0.

15. Change Proposal – Burch. Rousseau pointed out that the issue of exhaust discharge for

occupied spaces that were addressed in this change proposal is also being addressed as part of the overall exhaust/intake discussion being lead by Langowski. The committee agreed in principle with Burch’s proposal. a. Motion: Ninomura moved, and Rousseau seconded, that this proposal be accepted

for further study, with the following response: “Proposal is accepted in principle. It will be addressed in a future addendum that is currently in progress regarding separation of exhaust discharges and outside air intakes for these and other spaces.” Vote: Approved, 9-0-0.

16. Ultra-pure Air Presentation. Jim Callahan presented his opinions of the advantages of ultra-

pure air systems in operating rooms. 17. Addendum ad (Exam Room Air Change Rate) – One public review comment was

received. Ninomura indicated this topic would be deferred until Memarzadeh was able to participate in the discussion.

18. Addendum ae (FGI coordination items). Rousseau presented responses (copy attached,

prepared by Langowski) to public review comments. a. Motion: Rousseau moved, and Dombrowski seconded, that these responses be

provided to the commentors, and that this addendum proceed towards publication. Vote: Approved, 12-0-0.

19. Natural Ventilation. Based on discussions with Frank Mills, Ninomura suggested the

possibility of a task group or sub-committee to review and make recommendations on natural ventilation. Olmsted suggested a joint position paper from ASHRAE, ASHE and APIC. Sharp advised exterior noise should be considered. The consensus of the committee was agreement with the Chair’s suggestion. Ninomura asked for volunteers to email their interest to him. The following people expressed interest at the meeting: Mills, Sharp, Sheerin, Moeller, Flannery, Platt, Fauber, Hosking, Herrig, John. ACTION: Ninomura to create a task group or sub-committee.

20. Proposed Exhaust Air Discharge Addendum. ACTION: Langowski will review current

draft and incorporate comments from the Clinical Sub-committee. 21. Addendum tb, Switchable Pressure Controls. Rousseau presented revisions to Table 7-1

footnotes regarding switchable controls (copy attached), as discussed in Dallas. The committee had the following comments:

a. Hosking – clarify that only switching between positive, neutral and negative is

prohibited, not just increasing or decreasing the differential pressure.

5.

b. Langowski – allow for exhaust of toilets and similar spaces to be turned off.

c. Ninomura – relocated requirement to text from footnote.

ACTION: Rousseau will prepare a revised addendum.

22. Radiology Procedure Rooms. Langowski pointed out that the requirements for Imaging

Procedure Rooms were unclear. It was also pointed out that spaces for many current procedures (i.e. hybrid operating rooms) are not addressed. ACTION: Langowski and Herrig to prepare an addendum for review at the next meeting.

23. Procedure Room Requirements. Rousseau reported that Erickson had asked previously if

the current requirements for Procedure Rooms were still required, based on FGI’s new definition of what procedures are performed in a Procedure Room. ACTION: Rousseau to investigate and provide recommendation.

24. IC&P Webinar. Ninomura asked Olmsted to present his webinar on to the committee

(Interstate Highways of Cross Transmission of Micro-organisms in Health Care Facilities: Air, Water and Surfaces – Which is the Most Important?). This webinar is scheduled for February 26, 1pm EST. ACTION: Ninomura to provide log in details for the webinar.

25. Teleconferences. Rousseau suggested that previous teleconferences had produced useful

results, and proposed that one be planned for March or April of this year. Flannery suggested a permanent plan to have a teleconference between each Society meeting. The consensus of the committee was that this was a good idea.

26. Renumbering of Standard 170. Ninomura reported that someone from SSPC 62.1 had

suggested that Standard 170 be renumbered as 62.3 to keep the health care ventilation requirements in the Standard 62 family. The consensus of the committee was that this was not a good idea because the 170 terminology was now well known in the industry. Darwich suggested that a way to be seen as more separate from Standard 62.1 would be to review our Title, Purpose, and Scope and revise it to address more than just ventilation (which some would argue the current standard already does).

27. Health Care Programs at the 2015 Winter Meeting in Chicago. Herrig and Metayer

indicated that this meeting would have a health care track, and that TC 9.6 would support a program for us, if we wanted to present. Rousseau recommended the committee take advantage of this offer and opportunity.

28. Action Items.

a. Outstanding items from previous meetings.

1) Boldt – Cooling tower placement language (Item 23, Chicago

Interim).

2) Hermans – discuss outside/exhaust air recirculation research with TC9.6 (Item 17, San Antonio).

(Note: Addenda to Standard 170-2013 are currently published for free on the ASHRAE website at http://www.ashrae.org/standards-research--technology/standards-addenda.) Committee Notes are in yellow and would not be included in the Public Review version of the Addendum. Actual proposed changes to text are in green. Committee review notes during the New York Meeting are in red. 3. DEFINITIONS Committee Note, not included in Addendum text: No reason to make reference to FGI for further illumination of any of the concepts in the sentence to which this reference is applied. Proposing that this FGI reference be removed and replaced with the CDC reference which has specific AII room text in part IV. “Infection-Control and Ventilation Requirements for AII Rooms” . airborne infection isolation (AII): the isolation of patients infected with organisms spread by airborne droplet nuclei less than 5 μm in diameter (see FGI [2014] in Informative Appendix B see CDC [2003] and CDC [2005] in Informative Appendix B). For the purposes of this standard, the abbreviation “AII” refers to the room that provides isolation. (Keep reference) classification of surgeries:

procedure room (Class A surgery): provides minor surgical procedures performed under topical, local, or regional anesthesia without preoperative sedation. Excluded are intravenous, spinal, and epidural procedures, which are Class B or C surgeries.


operating room (Class B surgery): provides minor or major surgical procedures performed in conjunction with oral, parenteral, or intravenous sedation or performed with the patient under analgesic or dissociative drugs. operating room (Class C surgery): provides major surgical procedures that require general or regional block anesthesia and/or support of vital bodily functions.

Committee Note, not included in Addendum text: ACS 2000 is still the current reference. Proposing that this ACS reference remain in the Standard until it is deleted with the future addendum to remove the Class A/B/C terminology. From www.facs.org: 04GR-0001 Guidelines for Optimal Ambulatory Surgical Care and Office-Based Surgery Developed by the Board of Governors Committee on Ambulatory Surgical Care. A set of optimal educational guidelines to help the surgeon in the office practice of surgery provide this service to patients in an appropriate manner and in a safe environment. (May 2000). PRICE: Single copy: No charge Additional: $5 each 10 or more copies: $4.50 each (For more information on this method of classifying surgeries, see ACS [2000] in Informative Appendix B.) Committee Note, not included in Addendum text: CDC 2003 is still the current reference. Proposing that this CDC reference be maintained. immunocompromised patients: patients whose immune mechanisms are deficient because of immunologic disorders (e.g., human immunodeficiency virus [HIV] infection or congenital immune deficiency syndrome), chronic diseases (e.g., diabetes, cancer, emphysema, or cardiac failure), or immunosuppressive therapy (e.g., radiation, cytotoxic chemotherapy, antirejection medication, or steroids) (see CDC [2003] in Informative Appendix B). Committee Note, not included in Addendum text: Errata is coming to straighten out the diffuser Groups. Proposing that this reference to the proper version of the Fundamentals Handbook be added. nonaspirating diffuser: a diffuser that has unidirectional downward airflow from the ceiling with minimum entrainment of room air. Classified as ASHRAE Group E (see ASHRAE 2009 Fundamentals Chapter 20) , these diffusers generally have very low average velocity. For the purposes of this standard, the performance of these diffusers is to be measured in terms of average velocity. Don’t add 6.1.1 Ventilation Upon Loss of Electrical Power. The space ventilation and pressure relationship requirements of Table 7.1 be maintained for the following spaces, even in the event of loss of normal electrical power:

BSR/ASHRAE/ASHE Addendum References to ANSI/ASHRAE/ASHE Standard 170-2013, Ventilation of Health Care Facilities Committee Review Draft 8jan2014 a. AII rooms b. PE rooms c. Operating rooms (Class B and C surgery), including delivery rooms (Caesarean) Committee Note, not included in Addendum text: NFPA-99-2012 defines an Alternate Power Source as one “..intended to provide power during the interruption of the normal electrical service..” and that the Alternate Power Source consists of “..generator sets or battery systems..” So even though they don’t define “normal electrical power” directly it appears that our use of the reference is still accurate. Proposing that this NFPA reference be maintained. (For further information, see NFPA [2012] in Informative Appendix B.) Committee Note, not included in Addendum text: No reason to make reference to FGI for further illumination of any of the concepts in the sentence to which this reference is applied. Search in the FGI2014 text on the word “boiler” yields nothing related to this paragraph. Proposing that this FGI reference be removed. 6.1.2.1 Provide heat sources and essential accessories in number and arrangement sufficient to accommodate the facility needs (reserve capacity), even when any one of the heat sources or essential accessories is not operating due to a breakdown or routine maintenance. The capacity of the remaining source(s) shall be sufficient to provide for domestic hot water, sterilization, and dietary purposes and to provide heating for operating, delivery, birthing, labor, recovery, emergency, intensive care, nursery, and inpatient rooms. (For further information, see FGI [2010] in Informative Appendix B.) Fuel sufficient to support the owner’s facility operation plan upon loss of fuel service shall be provided on site. OK Committee Note, not included in Addendum text: 62.1-2010 (not 2013) is utilized. Section 5.4 Airstream Surfaces is still applicable. Proposing that this 62.1 reference be maintained. 6.2.1 Air-Handling-Unit Casing. The casing of the air-handling unit shall be designed to prevent water intrusion, resist corrosion, and permit access for inspection and maintenance. All airstream surfaces of air-handling units—e.g., interior surfaces and components—shall comply with Section 5.4 of ANSI/ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality.12 (For more information, see ASHRAE [2010b, 2005b] in Informative Appendix B.) Committee Note, not included in Addendum text: 62.1-2010 (not 2013) is utilized. Section 5.16.1 defines Class 1 air as “Air with low contaminant concentration, low sensory-irritation intensity, and inoffensive odor” and is still applicable. Proposing that this 62.1 reference be maintained. 6.3.1.2 Relief Air. Relief air is exempt from the 25-foot (8-metre) separation requirement. Relief air is defined as the Class 1 air (for further information see Standard 62.1 [ASHRAE 2010b] in Informative Appendix B) that could be returned to the air-handling unit from the occupied spaces but is being discharged to the outdoors to maintain building pressurization (such as during air-side economizer operation).

BSR/ASHRAE/ASHE Addendum References to ANSI/ASHRAE/ASHE Standard 170-2013, Ventilation of Health Care Facilities Committee Review Draft 8jan2014 Committee Note, not included in Addendum text: The SMACNA reference version is still the latest and is still applicable. Proposing that this SMACNA reference be maintained. 6.3.2 Exception: Ductwork located within mechanical equipment rooms. Positive-pressure exhaust ductwork located within mechanical equipment rooms shall be sealed in accordance with SMACNA duct leakage Seal Class A.10 Committee Note, not included in Addendum text: No reason to make reference to FGI for further illumination of any of the concepts in the sentence to which this reference is applied. Search in the FGI2014 text on the word “manometer” or “MERV” yields nothing related to this paragraph. Search in the FGI2014 text on the word “filter” yields 18 hits, but nothing related to this paragraph. Proposing that this FGI reference be removed. Search of the CDC document for “filter” only yields the statement to ensure that filters are “..properly installed and maintained to prevent air leakages and dust overloads.” and to “inspect filters periodically”. Proposing that this CDC reference be maintained. 6.4 Filtration. Filter banks shall be provided in accordance with Table 6.4. Each filter bank with an efficiency of greater than MERV 12 shall be provided with an installed manometer or differential pressure measuring device that is readily accessible and provides a reading of differential static pressure across the filter to indicate when the filter needs to be changed. (For further information, see FGI [2010] and CDC [2003] in Informative Appendix B.) All of the air provided to a space shall be filtered in accordance with Table 6.4, except as otherwise indicated in Section 7.1 for spaces that allow recirculating HVAC room units. OK Committee Note, not included in Addendum text: The IEST reference version dated 2005 does not currently exist, but a reference is still applicable. Proposing that this IEST reference be revised as noted. Table 6.4

d. High-Efficiency Particulate Air (HEPA) filters are those filters that remove at least 99.97% of 0.3 micron-sized particles at the rated flow in accordance with the testing methods of IEST RP-CC001.3 IEST RP-CC001.5 (IEST [20052010] in Informative Appendix B).

Interpretation IC 170-2008-X of ANSI/ASHRAE Standard 170-2008 Ventilation of Health Care Facilities

Date Approved:

Request from: Travis English ([email protected]), Kaiser Permanente, 1800 Harrision Street, Oakland, CA 94612. (Phone: 714-469-9553) Reference: This request for interpretation refers to the requirements in ANSI/ASHRAE/ASHE Standard 170-2008, Section 7and Table 7-1, regarding air change rates. Background: ASHRAE Standard 170 (S170) Section 7 states that the air change per hour (ACH) rates in Table 7-1 “The ventilation requirements of this standard are minimums that provide control of environmental comfort, asepsis [infection control and prevention], and odor in health care facilities.” The inclusion of “Minimum Total ACH” rates is unique to S170 and to health-care facilities, which account for 4.5% of the US commercial building stock [1]. The remaining 95% of commercial buildings do not have minimum ACH requirements for achieving indoor air quality, odor control, or comfort. Those commercial buildings are covered by ASHRAE Standard 55 (S55) and ASHRAE Standard 62.1 (S62).

1. Environmental comfort – Environmental comfort for all other commercial buildings is covered by S55. Most design engineers are familiar with S55, since all buildings seeking the LEED certification are required to formally submit S55 compliance documentation. (There is a useful, web-based tool for comfort compliance calculations available at http://www.cbe.berkeley.edu/comforttool/). No minimum total ACH rates are required by S55.

2. Odor – Odor for all other commercial buildings is covered by S62.1. This includes spaces where odors are primarily a function of human occupancy (public assembly, religious worship), and spaces where odors are produced by human activity combined with space contaminants (food service, food sales, mercantile). No minimum total ACH rates are required for any space in S62.

Section 7.1.1.a and 7.1.1.c make it clear that the ACH rates are mandatory minimums. No exceptions are allowed. This implies they are critical to the opening statement made in Section 7. By process of elimination, if “Minimum Total ACH” are not critical to comfort, and are not critical to odor control (else they would be required in all commercial buildings), they must be critical to infection control and prevention (which is unique to healthcare). [1] CBECS. 2003. Overview of Commercial Buildings, 2003 – Full Report. Energy Information Administration. Interpretation: Standard 170 asserts that each total air change rate listed in column 4 of table 7-1 is an established (i.e. research-based), mandatory requirement for infection control and

prevention (i.e. where 6 ACH is required, 5 ACH is demonstrably unacceptable to control or prevent infection). Question: Is this interpretation correct? Answer: No. Comments:

1. ASHRAE Standard 170 is based on research, authoritative guidance (such as CDC) and/or values proven over many years to yield effective results within the varied uses and occupancies of health care facilities.

Request from: Travis English ([email protected]), Kaiser Permanente, 1800 Harrision Street, Oakland, CA 94612. (Phone: 714-469-9553) Reference: This request for interpretation refers to the requirements in ANSI/ASHRAE/ASHE Standard 170-2008, Section 7and Table 7-1, regarding to simultaneous heating and cooling. Background: Reheat systems, such as constant air-volume with zone reheat (CAV-R), are energy-wasteful. They may be the single most inefficient HVAC system type [1]. This is long recognized. And, reheat, as a design practice, is prohibited by the energy standard ASHRAE Standard 90.1 (S90.1), Section 6.5.2 “Simultaneous Heating and Cooling Limitation”. However, S90.1 grants some limited exceptions to ban on reheat. S90.1 grants a specific exemption in Section 6.5.2.1, Exception a 4, for “The air flowrate required to comply with applicable codes or accreditation standards, such as pressure relationships or minimum air change rates.” For healthcare facilities, where ASHRAE Standard 170 (S170) has been adopted or adapted into jurisdictional regulation, Table 7-1 is the source of the “minimum air change rates” in those “codes and accreditation standards”. As such, any space with a “Total Air ACH” value listed in S170 Table 7-1, column 5, is exempt from S90.1Section 6.5.2. Those zones may use reheat. Please Note: A substantively similar RFI has been submitted to S90.1. [1] – Doty SP. 2009. Simultaneous Heating and Cooling – the HVAC Blight. Energy Engineering, 106(2):42-74 Interpretation: Standard 170 asserts that each space with a “Total Air ACH” entry listed in Table 7-1 has been considered, and is a warranted exception to the otherwise prohibited and energy-wasteful practice of simultaneous heating and cooling. Question: Is this interpretation correct? Answer: No Comments: Your request for interpretation regarding the application of Standard 90.1 (2010), Section 6.5.2 should be addressed to the SSPC 90.1 Committee since it appears that your question pertains to Section 6.5.2.1, Exception a 4.

Request from: Travis English ([email protected]), Kaiser Permanente, 1800 Harrision Street, Oakland, CA 94612. (Phone: 714-469-9553) Reference: This request for interpretation refers to the requirements in ANSI/ASHRAE/ASHE Standard 170-2008, Section 7and Table 7-1, regarding to ER Waiting and Radiology waiting rooms. Background: Healthcare buildings account for roughly 4.5% of commercial building footprint in the US [1]. And, for healthcare buildings, designers calculate outdoor air (OA) ventilation using the air change per hour (ACH) rates in ASHRAE Standard 170 (S170) Table 7.1. In the remaining commercial buildings, engineers calculate outdoor air ventilation rates using the ventilation rate procedure (VRP) of ASHRAE Standard 62.1 (S62.1). The VRP requires a per person component, a per square foot component, and a consideration of ventilation distribution effectiveness. The following is a comparison of ER waiting room cases, using both methodologies. For the S62.1 comparison, the waiting room is calculated as a "reception area", in a commercial office environment.

1. Case 1: A 300 square foot, low-density waiting room is designed with fixed seating for 10 people (30 square foot per person). The ceiling is 13 ft high, to create a feeling of space for the occupants.

2. Case 2: A 300 square foot, low-density waiting room is designed with fixed seating for 10 people (30 square foot per person). The ceiling is 7 ft 6 in high, based on structural constraints.

3. Case 3: A 300 square foot, high-density waiting room is designed with fixed seating for 20 people (30 square foot per person). The ceiling is 13 ft high, to create a feeling of space for the occupants.

4. Case 4: A 300 square foot, high-density waiting room is designed with fixed seating for 20 people (30 square foot per person). The ceiling is 7 ft 6 in high, based on structural constraints.

Calculations for each are shown in Table 1 below

Resultant outside air flows, in ACH, are shown in Figure 1 below. Air change per hour is constant using S170. ACH rate increases from case 1 to case 4 using S62.1.

Resultant outside air flows, in cfm per person, are shown in Figure 2 below. Cfm per person is fairly constant using S62.1. It decreases from case 1 to case 4 using 170.

Figure 2 – Cfm per person of all cases, using both standards.




The percent difference in cfm per person required by each standard is shown in Figure 3 below. For cases 2 and 3, the standards are aligned. Using S170, case 1 requires 72% more outside air than S62.1. This will increase energy the need for humidity control in the space. Using S170, case 4 requires 43% less outside air than S62.1. The fully occupied room would not have minimumaly acceptable indoor air quality, as defined by S62.1.

Figure 3 – Percent difference between S170 and S62.1 outside air cfm per person

If designers considered both S62.1 and S170 in the space, and chose the highest of the two, case 4 could be mitigated. However, an “ER Waiting Room” has no entry in the S62 VRP tables. S170 does not require designers to run dual calculations, nor would it be common practice to do so. Please Note: A substantively similar RFI has been submitted to S62.1. References: [1] – CBECS. 2003. Overview of Commercial Buildings. Energy Information Administration Interpretation: Standard 170 asserts that the need for outside air in ER and radiology waiting rooms is driven entirely by volume - that occupancy has no bearing on the need for outside air - though this is not aligned with normal ventilation design practice, can cause higher energy use when occupancy is low, and can cause sub-optimal indoor air quality when occupancy is high. Question: Is this interpretation correct? Answer: No Comments: The ventilation rates in these two room types have been selected to provide the dilution of respirable contagions such as TB from persons with undiagnosed TB.

Interpretation IC 170-2008-X of ANSI/ASHRAE/ASHE Standard 170-2008

Ventilation of Health Care Facilities

Date Approved: Request from: Abdel K. Darwich ([email protected]), Guttmann and Blaevoet Consulting Engineers, 800 Howe Avenue Ste 330, Sacramento, CA 95835. (Phone: 916-921-1956 x 213) Reference: This request for interpretation refers to the requirements in ANSI/ASHRAE/ASHE Standard 170-2008, Table 7-1, regarding outdoor air changes per hour (ACH) for hospitals. Background: For over 26 years ASHRAE Application Handbook included the following statement: “outdoor air, in comparison to (hospital) room air, virtually free of infectious bacteria and viruses” and currently documented in ASHRAE 2011 Applications Handbook Chapter 8, Page 8-2. In addition, since filters are not perfect and subject to maintenance, to reduce the risk of infectious bacteria and viruses, as compared to hospital recirculated air, ASHRAE Application Handbook Table 3 recognized that the IAQ resulted from 100% outdoor air is better. Therefore till 2003 ASHRAE Application Handbook Table 3 encouraged the use of 100% outside air by allowing for example reduced outside air in operating rooms when 100% outside air is used. In 2003 AHSRAE Application Handbook Table 3 ACH the requirements for operating rooms when 100% outside air was omitted resulted in same ACH criteria for 100% outdoor air as for recirculating air systems. The state of California elaborated on the use of 100% outside air with the intent to reduce the risk associated with hospital recirculated air as compared to outdoor air and continues to do so and encourage the use of 100% outdoor air. The state of California requirements for ventilation in hospitals as shown in Table 4-A of the California Mechanical Code (CMC) has separate Air Change per Hour (ACH) requirements for 100% Outdoor Air (OA) systems and for re-circulating systems. Typically, the ACH for 100% OA systems are lower because “outdoor air, in comparison to (hospital) room air, virtually free of infectious bacteria and viruses” as shown above. For example, an operating room ,which would require a total ACH of 20 and an OA ACH of 5 if it is a re-circulating system, would only require an OA (and Total) ACH of 12 if is a 100% OA system. Many systems in California are designed as 100% OA with heat recovery to take advantage of the superior outdoor air quality as compared to hospital recirculating air, and associated reduced airflow. A conflict arises when California hospitals are electing to pursue LEED-Healthcare or Joint Commission Accreditation; or meet CMS requirements which would trigger a requirement to comply with ASHRAE/ASHE Standard 170 which does not differentiate between re-circulating systems and 100% OA systems. Meeting the ASHRAE/ASHE Standard 170 requirements diminishes the energy savings associated with the reduced volume permitted by the CMC and defeats the purpose of the energy saving LEED is trying to achieve. Interpretation: A system designed to be 100% OA still needs to meet the total ACH required in Standard 170, Table 7-1. Question: Is this interpretation correct?




Answer: YES Comments: Per ASHRAE Standard 170-2008, paragraph 7.1.1c, “For design purposes, the minimum number of total air changes indicated shall be either supplied for positive pressure rooms or exhausted for negative pressure rooms.” No differentiation or exception is made for 100% OA systems.

Comment: Continued care nursery N/R 2 6N/R N/R No 30-60 72-78/22-26 Continues care nursery is proposed with a mandatory Minimum Total ach of 6 ACH. Any space identified in S170 Table 7-1 qualifies under exemption a4 to S90.1 Section 6.5.2. The space will be allowed to use a constant volume zone with reheat (CAV-R), a design which is otherwise prohibited by S90.1 section 6.5.2. Has this space been evaluated with a lower (or no) total ach and found to be unsafe or unacceptable? If so, for what reason? What is the justification for allowing or encouraging the use of CAV-R in the space? If this total ACH is not specifically justified, it should be N/R. Proposed Response: The addition of a new space to Table 7-1 as proposed in Addendum ae is part of the coordination that occurs regularly between Standard 170 and the FGI Guidelines for Design and Construction of Hospital and Health Care Facilities. Minimum requirements for the Addendum's new Continued care nursery space Table 7-1 entry were developed with knowledge of the Standard's existing minimum requirements for the Newborn nursery suite space. Standard 170 contains no minimum requirements for constant volume zone controls.

Comment 001/0002: Addendum Text: (b) Revise Section 7.2.1.e as shown below.

7.2.1 Airborne Infection Isolation (AII) Rooms. Ventilation for AII rooms shall meet the following requirements whenever an infectious patient occupies the room: e. The room envelope shall be sealed to limit leakage air flow at provide a

minimum differential pressure of 0.01 in. wc (2.5 Pa) differential pressure across the envelope.

Comment: RE 7.2.1e and 7.2.2a: “The room envelope shall be sealed to provide a minimum differential pressure of 0.01”wc across the envelope.” This statement is a bit vague, as it does not define a leakage rate of the room nor does it require a certain maximum airflow differential required to achieve this 0.01”wc minimum pressure differential. Please define leakage rate. Essentially one could achieve this 0.01”wc differential by increasing the airflow differential (ie exhaust minus supply on AII rooms and supply minus return on PE rooms) until this pressure differential is achieved. In our experience, this puts the burden of achieving the room pressurization on the HVAC system, which does not always have the flexibility for increased capacity and is very energy inefficient. Proposed Response: The committee chose to delete the phrase "leakage air flow" from the minimum Standard requirements with Addendum ae as this "leakage air flow" had no specific minimum requirement to which it could be "limited". The committee purposefully chose to not define a "leakage rate" to improve the ability to enforce the Standard by Authorities Having Jurisdiction. Note that the action phrase of the sentence is that the room envelope "shall be sealed". The burden of sealing the room envelope is typically with the general trades rather than with the HVAC system.

Comment 001/0003: Addendum Text: (e) To clarify horizontal distance between the outdoor intake and more serious exhaust streams indicated as shown below. 6.3.2 Exhaust Discharges. Exhaust discharge outlets that discharge air from AII rooms, bronchoscopy rooms, emergency department waiting rooms, nuclear medicine laboratories, radiology waiting rooms, and laboratory chemical fume hoods shall a. be designed so that all ductwork within the building is under negative pressure; Exception: Ductwork located within mechanical equipment rooms. Positive pressure exhaust ductwork located within mechanical equipment rooms shall be sealed in accordance with SMACNA duct leakage Seal Class A.10 b. discharge in a vertical direction at least 10 ft (3 m) above roof level and shall be

located not less than 10 25 ft horizontally from air intakes, openable windows/doors, or areas that are normally accessible to the public or maintenance personnel and that are higher in elevation than the exhaust discharge; and

c. be located such that they minimize the recirculation of exhausted air back into

the building. Comment: 6.3.2 Exhaust Discharges: Exhaust discharge outlets that discharge air from AII rooms, bronchoscopy rooms, emergency department waiting rooms, nuclear medicine laboratories, radiology waiting rooms, and laboratory chemical fune hoods shall Request that spaces occupied by HealthCare workers and public which do not require the occupant to utilize "protective measures" such as respierators be removed from this section and associated requirements for discharges 10 feet above the roof. Since people occupy the spaces, the air being discharged should be considered as "general exhaust".

n. If pressure monitoring device alarms are installed, allowances shall be made to prevent nuisance alarms. Short term excursions from

required pressure relationships shall be allowed while doors are moving or temporarily open. Simple visual methods such as smoke trail, ball-in-tube, or flutterstrip shall be permitted for verification of airflow direction. Controls intended to change the pressure relationship between spaces shall not be permitted.

u. The AII room described in this standard shall be used for isolating the airborne spread of infectious diseases, such as measles, varicella, or

tuberculosis. Supplemental recirculating devices using HEPA filters shall be permitted in the AII room to increase the equivalent room air exchanges; however, the minimum outdoor air changes of Table 7-1 are still required. AII rooms that are retrofitted from standard patient rooms from which it is impractical to exhaust directly outside may be recirculated with air from the AII room, provided that the air first passes through a HEPA filter. When the AII room is not utilized for airborne infection isolation, the pressure relationship to adjacent areas, when measured with the door closed, shall remain unchanged and the minimum total air change rate shall be 6 ach. Switching controls for reversible airflow provisions shall not be permitted.

Peter - Regarding the minutes note: about revising a footnote with the endo room discussion. The sentence I tossed out below: "The use of controls to switch between exhaust air systems and return air systems shall not be allowed when the space is programmed for bronchoscopy." is different than the other talk about disallowing switching pressures. Here we are concerned that they don't switch between systems.
