Free DOE energy modeling tools help cut energy use on residential and commercial buildings. Find it HERE The National Renewable Energy Laboratory worked withe the Department of Energy to produce the EnergyPlus program - a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings. Modeling the performance of a building with EnergyPlus enables building professionals to optimize the building design to use less energy and water.
Recovery Through Retrofit will make it easy for middle-class homeowners to learn what efficiency upgrades their homes need, and then get financing to make the improvements. One of the program’s cornerstones is the Home Energy Score, which Energy Secretary Steven Chu said will help standardize home energy audits.
