ASHRAE Releases Standard for Moisture-Control Design Analysis
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has released a new standard to address the challenges of using computer modeling programs to optimize a building design’s energy efficiency while minimizing the risk of moisture and mold problems.Standard 160-2009, “Criteria for Moisture-Control Design Analysis in Buildings,” is intended for use on commercial buildings (although it could be used for homes as well) and describes methods of calculating conditions for a model that will give the most accurate picture of a building’s moisture performance. The standard will likely be used to inform prescriptive building code language; a draft version of the standard was already used to craft requirements for vapor barriers in one code.
Standard 160 will be subject to ongoing review and revision; it is available for $39 at
