Addendum for Standard 62.1-2019, More Up for Public Review

From eSociety, March 2020


The following is under a 30-day public review from February 21 to March 22:

ANSI/ASHRAE Standard 62.1-2019, Ventilation for Acceptable Indoor Air Quality

1st Public Review of BSR/ASHRAE Addendum a:

At the publication of ANSI/ASHRAE Standard 62.1-2016 General Notes for Table Note 3 was modified editorially to conform the standard to standard language requirements but that has led to confusion as to whether density adjustments are required. Addendum s to 62.1-2016 relocated the table notes into the body of the standard. This proposed addendum modifies Section Air Density to clarify that air density adjustments are permitted but are not required.

The following is under a 45-day public review from February 21 to April 6:

1st Public Review of BSR/ASHRAE/SMACNA Standard 126-2016R, Methods of Testing HVAC Air Ducts

This standard provides laboratory test procedures for the evaluation of HVAC air ducts.

The following is under a 30-day public review from March 6 to April 5:

ANSI/ASHRAE Standard 15-2019, Safety Standard for Refrigeration Systems

1st Public Review of BSR/ASHRAE Addendum c:

This addendum proposes changes to allow the use of equipment using small amounts of non-A1 refrigerants, only if they are listed to appropriate product safety standards. The proposal is consistent with research findings, and the published requirements of product safety standards such as UL 484 and UL 60335-2-40.

The following is under a 45-day public review from March 6 to April 20:

1st Public Review of BSR/ASHRAE Standard 182-2008R, Method of Testing Absorption Water-Chilling and Water-Heating Packages

This revision of Standard 182-2008 prescribes a method of testing absorption water-chilling and water-heating packages to verify capacity and thermal energy input requirements at a specific set of operating conditions.

The following are under a 30-day public review from March 13 to April 12:

ANSI/ASHRAE Standard 185.1-2015, Method of Testing UV-C Lights for Use in Air-Handling Units or Air Ducts to Inactivate Airborne Microorganisms

2nd Public Review of BSR/ASHRAE Addendum b:

The use of the Poisson distribution is not appropriate for this type of biological data. The degree of correction is based on the total counts, so that a test with thousands of counts receives a tighter confidence interval than one with hundreds. This could result in very different reports efficiencies between tests. Also, since counting plates for microorganisms requires that the spots be separate, there is an upper limit on the raw counts per plate. In addition, the test lab must estimate the actual concentrations to determine how long to sample or how much to plate. This addendum reports the counts, the average, and the standard deviation to give an average efficiency and a measure of the sample count variability.


ANSI/ASHRAE Standard 185.2-2014, Method of Testing Ultraviolet Lamps for Use in HVAC&R Units or Air Ducts to Inactivate Microorganisms on Irradiated Surfaces

1st Public Review of BSR/ASHRAE Addendum a:

This addendum fixes an error in the original document. The intended airflow rate was 2000 cfm (500 fpm). This removes the unintended value and replaces it with the correct one.


The following is under a 30-day public review from February 21 to March 22:

Guideline 43P, Operations Guideline for Ventilation of Health Care Facilities. SSPC 170 is responsible for the development of this guideline.

PURPOSE: The purpose of this guideline is to provide information and guidance for the operation of ventilation systems that provide environmental control in new and existing health care facilities.


2.1 This guideline is intended for use by facility operators and those involved in the design, construction, installation, commissioning, management, operation, maintenance, accreditation, inspection, and service of health care facilities. 

This guideline applies to patient care areas, resident care areas, and related support areas within health care facilities.

2.2 This guideline considers chemical, physical, and biological contaminants that can affect the delivery of medical care to patients and residents, the convalescence of patients and residents, and the safety of patients, residents, health care workers, and visitors.

2.3 This guideline provides guidance for temperature and humidity.

2.4 This guideline provides guidance for odor control and asepsis.

2.5 This guideline provides guidance for ventilation rates including, but not limited to outdoor air, to serve health care facilities.

2.6 This guideline provides guidance for thermal comfort.


The following is under a 30-day public review from February 21 to March 22:

GPC 44P, Protecting Building Occupants from Smoke During Wildfire and Prescribed Burn Events


The purpose of this guideline is to recommend building measures to minimize occupant health impacts caused by smoke from wildfire and prescribed burn events.


2.1 This guideline applies to commercial buildings; institutional buildings, including healthcare facilities; and multi-unit residential buildings, as well as dedicated spaces within these building types intended for temporary human occupancy during a wildfire or prescribed burn event.

2.2 This guideline includes buildings expected to be occupied by potentially susceptible populations, including children and the elderly.

2.3 This guideline provides recommendations related to the design, installation, commissioning, operation, and maintenance of building.
