Heads up on ASHRAE 90.1 - 2013 and Its Impact on Commercial HVAC Design!

The Department of Energy (DOE) released a statement last month saying that ANSI/ASHRAE/IES Standard 90.1 - 2010 Energy Standard for Buildings Except Low-Rise Residential Buildings offers 8.5% source energy savings and 7.6% site energy savings over the 2010 version. That’s enough to warrant another round of changes to commercial building codes. State governments now officially have until September 26, 2016....
