ASHRAE proposes tweaks to standards, guidelines
Proposed changes affect safety, refrigerant classification, energy efficiency, and other areas affecting commercial construction.
ASHRAE is soliciting input on nearly three dozen changes to its standards. In addition, the ASHRAE is asking members to sound off on a proposal to withdraw a standard focused on cleaning.
The standards open for review include 15 (refrigerate safety), 34 (classification of refrigerants), 55 (thermal comfort), 90.1 (energy efficiency), 62.1 (ventilation), 62.2 (residential ventilation), and 135 (BACnet), and one guideline.
ASHRAE also is proposing withdrawal of Standard 52.1-1992, Gravimetric and Dust-Spot Procedures for Testing Air-Cleaning Devices Used in General Ventilation for Removing Particulate Matter. The most crucial features of the standard (regarding dust-holding capacity and arrestance) have been folded into Standard 52.2-2008, Method of Testing General Ventilation Air Cleaning Devices for Removal Efficiency by Particle Size, making the other standard all but redundant.
