Passive House Verification

Passive House is the gold standard for energy efficiency in single family and multi-family construction. Applying this rigorous standard results in ultra-low energy buildings that require very little energy for heating and cooling. Passive House combines a design verification protocol with a Quality Assurance/Control program performed by highly skilled PHIUS Raters/Verifiers.

The result is a high efficiency design that minimizes energy consumption and increases inhabitant comfort by focusing on high performance fenestration, robust insulation, near zero building envelope air leakage and simplified mechanical systems.

Our team holds both the Passive House Rater and Passive House Verifier certifications, allowing us to work on both high-rise and low-rise projects.  This specialization integrates well with our core function of HERS Ratings, giving you code compliance documentation and Passive House verification from one source.

Our partnership with New England Air Barrier means that meeting the strict Passive House air infiltration rates of 0.6 air changes per hour (ACH) is now easier and more affordable than ever before.  Utilizing the AeroBarrier aerosolized air-sealing system you can hit your ACH target early in the project and take comfort in knowing the results are guaranteed.
