In the age of high-thermal-performance building envelopes, there can be many surprises when the designed wall system does not meet the expected performance criteria. Sometimes these ‘misses’ are significant and can severely impact the energy use for a building.
As consulting engineers continually specify more sustainable HVAC technologies, they must ensure their designs comply with a variety of standards. Of course, when possible, it is even better to go far beyond those baseline requirements.
Proposed changes regarding lighting and climate zones to energy standards published by the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) and the Illuminating Engineering Society (IES) are open for public discussion.
The American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) and the International Code Council (ICC) signed a deal outlining each organization’s role with the International Green Construction Code (IgCC).
The goal of a room air distribution system is to provide thermal comfort and a healthy living environment for occupants in the space. This article looks at designing such assemblies for comfort and indoor air quality (IAQ) per ASHRAE 55 and 62.1.
