Infrared Thermography Project

The owner of this 1893 greenhouse asked BPA if we could conduct an envelope air leakage study to help them plan for an energy retrofit.  While glass oftentimes simply reflects infrared light, making thermal imaging difficult, BPA accepted the challenge. 

BPA studied the building, used blower door fans to measure the envelope air leakage, and used infrared thermography to find the air leakage locations, which showed up remarkably well despite the IR-reflective properties of glass. 

BPA benchmarked the greenhouse’s envelope air leakage against industry standards, and provided a quantitative and qualitative, written and illustrated report enumerating the test data, showing where air leaks occurred, and making recommendations on how to air seal the air leak locations.
