Building energy modeling allows project teams to not only better understand the look of the building/renovation scope, but also understand the functionality and future usage of the building, as well as the efficiency, much like the MPG of a car. This approach to simulating the performance of a building is so valuable that it has become a standard way of measuring and predicting building energy consumption. Results are often used to show compliance with building energy codes, local laws, and green-building/certification program standards. A few examples of this include the ENERGY STARⓇ certification program, USGBC’s LEED rating systems, HERS ratings, ASHRAE 90.1, utility energy efficiency incentive programs, and even federal tax credits like 45L.
