The Building Performance Institute (BPI) is the nation's leading building science accreditation


Their "house as a system" philosophy looks at a building's various components (building envelope, attic, basement, combustion equipment, ventilation sources) and the interrelationship between them to maximize a home's performance. This approach leads to greater energy efficiency, but perhaps more importantly, to buildings that simply work better.

A home that has been analyzed and upgraded from a whole-house standpoint is more durable, healthier, more comfortable, and more energy efficient.

Our specific certifications include:

  • Building Analysis Certification
  • Building Envelope Certification
