Public Reviews, September 2018

These drafts are scheduled for a 30-day public review from Sept. 7 to Oct. 7:

1. 1st Public Review of BSR/ASHRAE Addendum b to ANSI/ASHRAE Standard 55-2017, Thermal Environmental Conditions for Human Occupancy

This proposed addendum updates the computer code for calculation of PMV-PPD using the JavaScript language to ease the use of the code in modern software applications. The updated code also includes errata previously published for Standard 55-2013 and aligns the code with requirements in Standard 55-2017.

2. 1st Public Review of BSR/ASHRAE Addendum c to ANSI/ASHRAE Standard 55-2017, Thermal Environmental Conditions for Human Occupancy

This proposed addendum adds a requirement for projects demonstrating compliance through Section 5.3.1, 5.3.2, or 5.3.3, design compliance to indicate the Comfort Control Classification Levels proposed through the addendum.

These drafts are scheduled for a 45-day public review from Sept. 21 to Nov. 5:

1.    BSR/ASHRAE Addendum L to ANSI/ASHRAE Standard 62.1-2016, Ventilation for Acceptable Indoor Air Quality (Second Public Review Draft)

The natural ventilation procedure was modified to require mechanical ventilation with certain exceptions. This proposed addendum provides specific requirements for the exception. It also recognizes that there are inherent health issues with outdoor air in many locations in the world and updates the requirements based on recent studies and airflow evaluations. The prescriptive path has been improved by removing the openable area requirement of 4% of net occupiable floor area. Two tables are proposed that provided minimum openable area based on program type, opening geometry, and spacing of vertical openings.

2.    BSR/ASHRAE Addendum t to ANSI/ASHRAE Standard 62.1-2016, Ventilation for Acceptable Indoor Air Quality (Second Public Review Draft)

This proposed addendum adds a new informative appendix which is a companion to the changes to the Natural Ventilation Procedure. It provides information for application of the new procedure.

These drafts are scheduled for a 30-day public review from Sept. 21 to Oct. 21:

1.    BSR/ASHRAE Addendum c to ANSI/ASHRAE Standard 62.2-2016, Ventilation and Acceptable Indoor Air Quality in Residential Buildings (Second Public Review Draft)

This proposed addendum aims to minimize the potential for coming up with variable ventilation control strategies that could result in substantial under-ventilation for noticeable periods of time.

2.    BSR/ASHRAE Addendum r to ANSI/ASHRAE Standard 62.2-2016, Ventilation and Acceptable Indoor Air Quality in Residential Buildings (First Public Review Draft)

This proposed change removes the requirement that ON-OFF controls be readily accessible or manual. They would still be required to be accessible, but would avoid the confusion between the 62.2 intent of “readily” with other organizations’ definition.

3.    BSR/ASHRAE Addendum t to ANSI/ASHRAE Standard 62.2-2016, Ventilation and Acceptable Indoor Air Quality in Residential Buildings (First Public Review Draft)

This proposed change removes the potential for people to claim they would have installed a balanced system to avoid installing an unbalanced system. It also aligns the maximum airflow requirement that precludes the need to install a fan between new and existing homes.

4.    BSR/ASHRAE Addendum u to ANSI/ASHRAE Standard 62.2-2016, Ventilation and Acceptable Indoor Air Quality in Residential Buildings (First Public Review Draft)

This proposed change expands the prescriptive duct sizing table (Table 5.3) to account for the larger flows sometimes encountered with kitchen exhaust. It also reworks the table to show minimum diameter instead of maximum length.

This draft is scheduled for a 30-day public review from Sept. 7 to Oct. 7:

2nd Public Review of BSR/ASHRAE/IES Addendum dn to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings

This addendum revises two exceptions to requirement to use energy recovery in section 6.5.6.1. One change limits the exception for solar heating to cooler climates. The second clarifies the exemption for the use of “energy recovery in series with the cooling coil” by creating a new definition for series energy recovery.

The following are under a 45-day Public Review from Aug. 17 to Oct. 1:

1. 1st Public Review of BSR/ASHRAE Addendum br to ANSI/ASHRAE Standard 135-2016, BACnet - A Data Communication Protocol for Building Automation and Control Networks

2. 1st Public Review of BSR/ASHRAE Addendum bt to ANSI/ASHRAE Standard 135-2016, BACnet - A Data Communication Protocol for Building Automation and Control Networks

This addendum adds re-alert transitions to the CHANGE_OF_LIFE_SAFETY event algorithm, specific error codes for LifeSafetyOperation error situations and support for elevator based occupant evacuation (OEO) to the life safety objects.

3. 1st Public Review of BSR/ASHRAE Addendum bu to ANSI/ASHRAE Standard 135-2016, BACnet - A Data Communication Protocol for Building Automation and Control Networks

This addendum proposes a Fault Detection and Diagnostics (FDD) requirement will reduce that degradation by detecting existing and future malfunctioning systems and notifying building operators so that actions may be taken to reduce energy consumption of the building. Additionally, FDD systems are being utilized to drive operational efficiency, make better use of maintenance personnel, and resolve comfort issues.
