ASHRAE Updates Standard 90.1
The user's manual for ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, has been recently revised.
The manual has been through an extensive revision process to incorporate the various addenda approved since the 2004 edition, according to Keith Emerson, who oversaw review of the manual for the Standard 90.1 committee. Since the 2004 edition was published, 44 addenda have been approved and are now incorporated into the manual.
Updates have been made to reflect and illustrate the changes in every portion of the 90.1 Standard. Appendix G changes have also been made.
The 90.1-2007 user's manual provides detailed instruction, calculation examples and compliance forms for the design of commercial and high-rise residential buildings. It includes sections on administration and enforcement, building envelope, HVAC systems, service water heating, power, lighting, the energy cost budget method and the building performance rating method.
