Building Performance Institute (BPI)

At Provision Environmental Systems & Testing, we believe that expertise and accountability set us apart. That’s why our technicians maintain professional certifications through the Building Performance Institute (BPI), the nation’s leading credentialing organization for home and building performance.

What is BPI?

Founded in 1993, the Building Performance Institute is a nonprofit organization that sets the standard for home performance testing, energy efficiency, and building science. BPI works in partnership with the U.S. Department of Energy (DOE) and the Environmental Protection Agency (EPA) to create nationally recognized certifications, accreditation standards, and quality assurance protocols.

BPI-certified professionals are trained and tested in areas such as:

Building science and energy efficiency
Air leakage and duct leakage diagnostics
Combustion safety and indoor air quality
HVAC performance and comfort optimization
Code compliance and energy program requirements

For clients, choosing a BPI-certified contractor means working with a team that follows proven, science-based methods for diagnosing problems and delivering lasting solutions.

Our BPI Certifications

Building Analysis Technician (BA-T)

This certification qualifies our team to evaluate whole-building performance using advanced diagnostic tools and building science techniques. As Building Analysis Technicians, we:

Conduct blower door tests to assess overall building tightness.
Identify sources of energy loss such as air leaks, insulation gaps, and inefficient windows.
Diagnose comfort issues like uneven temperatures, drafts, or high humidity.
Ensure mechanical ventilation systems are safe and effective.
Provide prioritized, cost-effective recommendations for improving energy efficiency and indoor air quality.

Why this matters for you: A Building Analysis Technician ensures your home or building is tested as a complete system, not just as individual parts. This holistic approach results in better comfort, healthier indoor air, and lower utility bills.

Infiltration & Duct Leakage (IDL)

This certification focuses specifically on air leakage through building envelopes and duct systems—two of the most significant hidden causes of wasted energy and reduced comfort. As certified IDL specialists, we:

Perform blower door testing to measure uncontrolled air infiltration through walls, ceilings, and foundations.
Conduct duct pressurization tests to measure leakage in HVAC ductwork.
Identify where conditioned air is escaping into attics, crawlspaces, or outdoors.
Verify duct sealing and weatherization improvements meet performance standards.

Why this matters for you: Leaky buildings and duct systems can waste 20–40% of conditioned air, forcing HVAC equipment to work harder and driving up energy costs. Our testing ensures your system delivers air where it’s designed to go—improving efficiency, comfort, and system longevity.
