ANSI/ASHRAE Standard 62.1-2016, Ventilation for Acceptable Indoor Air Quality
The following is under a 45-day public review from September 6 to October 21:
2nd Public Review of BSR/ASHRAE Addendum ag
This proposed addendum replaces the calculation method in current Normative Appendix B2 (Separation of Exhaust Outlets and Outdoor Air Intakes) with a new method based upon ASHRAE RP-1635 (2016). This research was sponsored by ASHRAE TC 4.3. The purpose of this Research Project is to provide a simple, yet accurate procedure for calculating the minimum distance required between the outlet of an exhaust system and the outdoor air intake to a ventilation system to avoid re-entrainment of exhaust gases. The new procedure addresses the technical deficiencies in the simplified equations and tables that are currently in Standard 62.1-2016 and model building codes.
ANSI/ASHRAE Standard 62.2-2016, Ventilation and Acceptable Indoor Air Quality in Residential Buildings
The following is under a 45-day public review from September 6 to October 21:
1st Public Review of BSR/ASHRAE Addendum y
This proposed addendum is intended to address concerns regarding ventilation of new multifamily dwellings that are accessed by an enclosed common corridor where the operation of exhaust systems may draw air from the corridor. It is possible that corridor air may be contaminated and not suitable for use as makeup air for exhaust systems. Supply and balanced systems are allowed because they are less likely to introduce corridor air to the dwelling.
BSR/ASHRAE Standard 118.1-2012R, Method of Testing for Rating Commercial Gas, Electric and Oil Service Water Heating Equipment
The following is under a 45-day public review from September 27 to November 11:
3rd ISC Public Review of BSR/ASHRAE Standard 118.1-2012R
This revision of Standard 118.1-2012 updates the scope to be consistent with the Department of Energy’s July 15, 2015, final rule that establishes new definitions for “commercial” and “residential duty commercial” water heaters and revises the definitions of heat pump water heaters. Test methods and calculations are revised for all heat-pump water heaters. The revision also updates Setting Outlet Water Temperature for Heating capacity for Type 1, Type II, Type III, Type IV, and Type V heaters, adds new Standby Loss test method and calculations for Type II and Type III Instantaneous Waters, and updates references.
ANSI/ASHRAE Standard 169-2013, Climatic Data for Building Design Standards
The following is under a 45-day public review from September 20 to November 4:
1st Public Review of BSR/ASHRAE Addendum a
This addendum adds new definitions, abbreviations, and acronyms and completely revises and updates the data and Tables.
ANSI/ASHRAE/ASHE Standard 170-2017, Ventilation of Health Care Facilities
The following are under a 45-day public review from September 6 to October 21:
This proposed addendum clarifies filtration requirements on a space by space basis. The filtration levels designated, and their rational basis are included in Informative Appendix C, Table C-1. In brief, this proposed addendum:
(1) revises requirements for filters in the body of the standard, removes Table 6.4, and adds filter efficiencies by space to Table 7-1, 8-1, and 9-1;
(2) adds Informative Appendix C: Recommended Filter Efficiencies by Space Type.
- 1st Public Review of BSR/ASHRAE/ASHE Addendum j
Proposed Addendum j continues the process of reorganizing the standard into three components—Hospital, Outpatient, and Residential Health Care and Support in alignment with the FGI Guidelines. The intent is not to create additional requirements for outpatient or residential facilities but to separate these from hospital requirements and thus eliminate confusion over which requirements apply to which occupancies. The result will be clarification of a lower level of requirements for outpatient and residential health facilities. Generally, the changes are:
(1) incorporate Addendum a updated filtration requirements;
(2) revise the space name terminology, table organization, and subheadings.
- 2nd Public Review of BSR/ASHRAE/ASHE Addendum o
Infection prevention and control (IPC) strategies include risk assessment, identification of people receiving care who are at increased risk of infection due to procedures and therapy they are undergoing and aligns the environment of care to mitigate risks. IPC strategies also identify and segregate those with communicable disease to spatially separate them from others at risk. This can be done through engineering controls, but it can also be accomplished through operational/administrative controls. This experience is therefore the basis for offering a risk-based approach to operation that departs from space requirements. For those health care providers that have the expertise to analyze, implement, and document their specific ventilation requirements, this proposed addendum provides a voluntary risk-based approach to establish operational ventilation rates for spaces required in this standard.
BSR/ASHRAE Standard 217- 201x, Non-Emergency Ventilation in Enclosed Road, Rail and Mass Transit Facilities
The following is under a 45-day public review from September 27 to November 11:
1st Public Review of BSR/ASHRAE Standard 217-201x
ASHRAE Standard 217-201x provides minimum ventilation requirements for ventilation systems within enclosed transportation facilities during non-emergency operating conditions.
BSR/ASHRAE Standard 221-201x, Test Method to Field-Measure and Score the Cooling and Heating Performance of an Installed Unitary HVAC System
The following is under a 45-day public review from September 27 to November 11:
3rd Public Review of BSR/ASHRAE Standard 221-201x
The purpose of ASHRAE Standard 221-201x is to prescribe a field evaluation and test method to measure and score the performance, in terms of delivered cooling or heating capacity, or cooling efficiency, of an installed unitary HVAC system.
ASHRAE Guideline 12-2000R, Managing the Risk of Legionellosis Associated with Building Water Systems
The following is under a 30-day public review from October 11 to November 10:
4th ISC Public Review of ASHRAE Guideline 12-2000R
This independent substantive change to the previous public review draft reflects input from comments received during the third public review.
ASHRAE Guideline 27P, Measurement Procedures for Gaseous Contaminants in Commercial Buildings
The following is under a 30-day public review from September 27 to October 27:
6th ISC Public Review of ASHRAE Guideline 27P
Guideline 27P provides recommended procedures for effective measurement of airborne gas and vapor concentrations inside commercial buildings. Its goal is to provide consistent procedures to follow so field measurements of contaminant concentrations are accurate and reproducible, avoiding typical problems that may cause unreliable or inconsistent results, while recommending sample acquisition techniques, sampling locations in equipment and spaces, sampling requirements and criteria for data analysis.
