New Product Preview Advertising Section Airtightness Testing - Not Just for Homes Anymore Airtightness testing of homes has been around for more than 20 years. Various energy programs and uctuating energy bills have provided homeowners an incentive to improve the airtightness of their homes. Energy tax credits can also be received by the homeowner but only if the house airtightness has been veri ed that it is less leaky after remodeling than before. In England, airtightness testing of buildings over 10,000 square feet was the rst regulation initiated to reduce energy consumption. Efforts to make commercial buildings more energy ef cient in the U.S. has only recently been incorporated into various “green” initiatives. Tests of commercial buildings show that they tend to be more leaky than the average house, based on air leakage per square foot of surface area. That means that commercial buildings are less energy ef cient than the average house. To measure the actual airtightness of a large building means more air is needed to maintain a reasonable test pressure. The Energy Conservatory, a leader in airtightness testing, has kits available to directly measure more than 18,000 cubic feet per minute of air leakage. Multiple kits and fans can be used simultaneously to generate more air for accurate and reliable measurements of air leakage for testing before and after retro tting. For more information on multi-fan systems contact The Energy Conservatory at 612-827-1117 or visit our website at www.energyconservatory.com. DIAGNOSTIC TOOLS TO MEASURE BUILDING PERFORMANCE Minneapolis Blower Door™ The Leader in Airtightness Testing Blower Door tests are used to measure the airtightness level of building envelopes, diagnose and demonstrate air leakage problems, estimate natural infiltration rates, estimate efficiency losses from building air leakage, and certify construction integrity.
