   The proposed energy cost budget must be less than or equal to the baseline energy cost budget to achieve compliance. The performance approach is also used to demonstrate design energy efficiency, often expressed as percent better than ASHRAE Standard 90.1. Building designs will stated their performance as "40% better than ASHRAE 90.1-2007" or ...
