Building / Home Performance Contractors run businesses that design and install whole-house energy measures to increase the thermal performance of residential buildings, often with a specialization in blower door-guided air sealing and insulation of the building enclosure.
Home performance contracting is a building science-based approach to treating a house as a system, utilizing diagnostic tools, and making home improvements that draw upon the contractor’s experiences in general contracting, remodeling, HVAC, plumbing, or insulating. Certified Home Performance Contractors help homeowners solve problems in their homes such as discomfort, indoor air quality and moisture issues, teach them about combustion safety, and help homeowners take measures that will reduce their energy bills and lessen their carbon footprint. Home Performance Contractors use specialized tools to diagnose homes, conducting a comprehensive home energy assessment, before making any suggestions for improvement. Certified Home Performance Contractors have invested in course work and have passed rigorous tests. They are knowledgeable not only about a home’s HVAC system but also the home’s building envelope and how all of these parts interact.
