Residential Solutions has two components to help residential customers improve the energy efficiency of their homes – the Quick Energy Savings Test (QuEST) and Home Performance with ENERGY STAR. QuEST provides low-cost energy assessments (or "audits") for residential customers, using a checklist and a visual inspection of the home. Home Performance with ENERGY STAR provides a comprehensive analysis of energy usage in the home through diagnostic equipment.
Home Performance with ENERGY STAR is a program created by the federal government which uses a whole-house approach to making a home more energy-efficient, thus lowering its energy consumption. Each participating contractor has staff certified by the Building Performance Institute (BPI). Only contractors with BPI certified staff can participate in the Home Performance with ENERGY STAR piece of the Residential Solutions Program. These contractors use advanced diagnostic equipment to test the home and identify energy efficiency improvements.
