The newly published American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) Standard 90.1-2013 has been adopted in many States and contains many changes from the previous versions. The Standard 90.1 is the energy guideline for commercial buildings except low-rise residential buildings and has a significant impact on both the engineering and architectural designs. The most significant changes involve Building Envelope, Lighting, Lighting Control, Mechanical Systems, and Compliance Paths.
