The Texas State Energy Conservation Office presents an overview of ASHRAE Standard 90.1 2010, the required code for state-funded buildings. This is Part 2 of a five-part series. This second video covers envelope provisions including wall, roof, and fenestration, and envelope compliance paths. The workshop is intended for engineers, architects, and code officials, who anticipate either applying, conforming to, or evaluating the latest ASHRAE energy efficiency standards for commercial building projects in Texas.
