Guidance on how to incorporate changes regarding building envelope, lighting, mechanical, and the energy cost budget in the 2013 energy standard from ASHRAE and IES are included in a newly published User’s Manual.

ANSI/ASHRAE/IES Standard 90.1-2013, “Energy Standard for Buildings Except Low-Rise Residential Buildings,” incorporates 110 addenda, reflecting changes made through the public review process.

Because the standard is written in mandatory language and is not intended as a design specification or an instruction manual, the User’s Manual was developed to minimize multiple interpretations of Standard 90.1 that may occur.

According to ASHRAE officials, the manual helps users of the standard understand its principles and requirements and how to comply with them. It also includes measurements and calculations in both I-P and SI units, making it usable with either edition of Standard 90.1.

The book includes sample calculations, application examples, and references to resources and websites. It is intended for architects, engineers, contractors, code officials and other building professionals, and is also suitable for use in educational programs.

In addition, purchasers of this User’s Manual can download compliance forms and tools from

“Including all the forms and instructions together in one location versus including them in print allows users to download the package for continual use in their business,” said Drake Erbe, Standard 90.1 committee chair.
