90.1 ECB App Demo

A tool for modeling compliance with ASHRAE Standard 90.1-2010

What This Tool Can Do for You:

Free Web Application

A free web application from ASHRAE automates the calculations needed to show a building project’s compliance with ASHRAE/IES Standard 90.1-2010 using the Energy Cost Budget (ECB) Method described in the standard. The calculations are based on the ECB Method Compliance Forms found in the 90.1-2010 User's Manual.

Input your project parameters and then calculate your proposed design’s projected performance and compliance—no need to build your own spreadsheet. Output your results in Microsoft® Excel® for your clients and project records.

The app is accessible from your desktop, tablet, or other device anywhere. Set up an account  and store your project information in one place for easy reference and comparison.
