To test for Air leakage in both new and older offices, VerdaTech offers a blower door service that measures the flow rate of air through cracks and openings in your office. The testing process gives accurate measurements to identify areas that are poorly sealed, in need of improvement, or repair.

Benefits

Blower door testing is an excellent method for testing leakage in a home to identify:

• Uncomfortable Drafts
• Heat loss areas of your office
• How to increase your office's efficiency

A blower door test is a quick way to identify improvements that can be made to your house to reduce heat loss and ultimately your heating bill.

Once a blower door test has been complete, the VerdaTech Energy Expert will identify and explain the values observed during the testing. At that time, the advisor will be happy to help answer any questions you may have about the testing or the results.

Blower Door Process

To perform a thorough energy efficiency analysis of your home, VerdaTech Energy Experts use specially designed "blower door" test equipment to measure your home's rate of air leakage.

The blower door is a variable-speed fan mounted on an adjustable panel that can fit into any exterior door opening of your home. Here’s how the test is run:

1. Reduce house pressure. When the fan is turned on, the pressure inside your home is gradually reduced to allow outside air to flow into the house through unsealed openings or cracks in the house structure.

2. Measure airflow rate. Pressure gauges connected to the fan measure the rate of airflow required to keep your home at a constant pressure so that the advisor can calculate your home's resistance to air infiltration.

3. Calculate energy efficiency. The results of the test are incorporated into your home's energy efficiency rating. Because airtight homes are energy efficient, a house that has little air leakage will result in a higher rating than a home that has a lot of air leakage.

4. Check ventilation. Advisors also ensure that the home is adequately ventilated as part of their analysis because modern airtight homes must always be adequately ventilated, usually with mechanical ventilation.
