WECC established the Wisconsin Energy Efficiency Program (WE2), a residential and commercial energy efficiency program for the City of Milwaukee, Madison, and Racine

WE2 offered project development services, rebates, and financing to achieve a goal of better than 15 percent energy savings in buildings. WECC managed all aspects of program design and delivery with program funding provided through a U.S DOE Energy Efficiency Conservation Block Grant for the Better Buildings Neighborhood Program. Energy efficiency upgrades were completed on 2,000+ residential (single- and multi-family) and 300 commercial buildings with actual average energy savings per building of 30 percent, doubling the grant goal.

Back of the Envelope Calculator

ECW saw that design professionals needed better information early in the building design process to make good energy decisions. We created the Back of the Envelope Calculator – a free, online tool that allows design professionals to make early decisions about the building as an energy system. Architects and engineers can enter various design parameters, see real-time connections between components, isolate the effects of changing one parameter, and produce concept-level energy estimates. To date, the tool has been used by thousands of professionals nationwide.
