WattShed is national software for designing and administering residential energy-efficiency rebate programs. A public, no-login designer covers all 50 states and DC, with methodology offerings that vary by location. Milam County, Texas is the case study used to demonstrate the authenticated resident journey. The wider product turns program terms, homeowner evidence, deterministic calculations, and contractor milestones into an auditable operating record.
