Performance Testing

Keen Living offers testing to give you a clear, data-driven understanding of your building’s performance: 

DET Duct Envelope Tightness & Blower Door Testing

DET tests measure air leakage of the building envelope and ductwork. These tests are required in new construction to meet building codes, and to earn the Energy Star and National Green Building Standard certifications.

In existing buildings, DET tests are used to establish a pre-retrofit baseline and to find big leaks that are causing comfort problems, moisture issues, or high energy bills.

Ventilation and Filtration Assessment

A ventilation and filtration assessment is included for all projects pursuing Energy Star and Indoor Air Plus certifications. It’s also a standalone service for clients who want better-than-average indoor air quality, or suspect there’s a problem with their current set-up. Call Keen Living and find out how to make your home healthier.
