ASHRAE New Standard 90.1 Portal Offers Centralized Resources to Users

ATLANTA (Jan. 25, 2018) – A new online portal makes it easier than ever for building professionals to access the suite of resources related to ASHRAE Standard 90.1 – Energy Standard for Buildings Except Low-Rise Residential Buildings.

“ASHRAE Standard 90.1 is used globally as an industry benchmark for setting minimum energy performance standards and energy codes,” says Drake Erbe, chair of ASHRAE’s Standard 90.1 committee. “Bringing all 90.1-related resources together in one location will empower building professionals to focus more on delivering energy efficiency requirements, knowing they have access to the most current Standard 90.1 information.”

Users will visit to set up login credentials and access the portal. Once inside, users can personalize their experience to access up-to-date Standard 90.1 resources in one consolidated location. Features of the portal include:

  • A multi-publication online tool that enables users to view each publication side by side or separately, as well as copy, paste, print or annotate content as needed.
  • The ability to view official ASHRAE Interpretations in the context where they matter.
  • Access to Standard 90.1 User’s Manual, which provides detailed instruction for design of commercial and high-rise residential buildings to ensure standard compliance. The user’s manual also includes measurements and calculations in both I-P and SI units, sample calculations, application examples, forms to demonstrate compliance, and references to related resources and websites.
  • A redlined version of Standard 90.1 showing what changes were made from the previous edition.

“Standard 90. 1 has proven to be an indispensable reference for engineers and other professionals involved in the design of buildings and building systems. The 90.1 Portal will be a helpful companion resource for users,” says Erbe.
