ASHRAE has announced a new web application that automates the calculations needed to show a building project’s compliance with Standard 90.1-2010. The 90.1 ECB web application is a tool for modeling compliance using the Energy Cost Budget (ECB) method in the standard.

A newly published document from ASHRAE and the Illuminating Engineering Society (IES) gives users of their energy efficiency standard access to an optional third path for compliance, providing more flexibility for the industry.

Twenty-three addenda to the energy standard published by ASHRAE and the Illuminating Engineering Society (IES) — ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings — are currently open for public comment.
