Most states apply the standard or equivalent standards for all commercial buildings. Many states apply ASHRAE 90.1 to buildings being constructed or under renovation.

Status as an energy code and industry standard Percent improvement over ASHRAE 90.1 is the basis for awarding energy points within the LEED rating system. Building designs will stated their performance as "40% better than ASHRAE 90.1-2007" or "20% better than ASHRAE 90.1-2010". The performance approach is also used to demonstrate design energy efficiency, often expressed as percent better than ASHRAE Standard 90.1. The proposed energy cost budget must be less than or equal to the baseline energy cost budget to achieve compliance. The ECB is expressed in units of dollars.Ī building performance simulation is then performed on the proposed building design. This baseline ECB is established using building performance simulation to model a building with the same size and program as the project building, built according to the prescriptive requirements of ASHRAE 90.1 (sections 5-10). In the performance approach, a baseline energy cost budget ( ECB) is established, based on the building size and program.
