We combine IR imaging with a Blower Door test

A Blower door is used to check how air-tight a structure is. Blower door tests are included with all energy assessments and can be carried out on residential homes, commercial structures, and industrial buildings.

In addition to the standard Blower door test we also do an InfraRed (IR) thermal scan with the blower door running. Thermal videography is used to locate and identify air leaks and poorly insulated area in the building. This is a powerful method that will help the advisor and building owners to develop a stategy to improve building envelope tightness, proper ventilation, reduce energy usage and increase occupant comfort and health.

Thermograms or IR Photos that show heat patterns and anomalies. It is very useful as it can be done quickly and it is non-destructive.

• Detecting Heat Loss: Thermal scans can identify areas where heat is escaping from a building, helping to pinpoint insulation issues. (It is like seeing through walls)
• Finding Air Leaks: The scans can reveal air leaks in the building envelope, which can be addressed to improve energy efficiency. (With the blower door increasing the air flow through openings to the outside, it is easier to locate dificiencies as outside air will show up as a different color depending on the season or the teprature difference between the inside and the outside of the building)
• Water Leak Inspections: IR Imaging can detect wet insulation or roof leaks by showing temperature differences caused by moisture.
• Visual Feedback: When used during construction is a powerful teaching tool that will help guide builders and their subcontractors to produce beter airtight buildings. (One Picture is better than a thousand words)
