A 2005 study by the National Institute of Science and Technology (NIST), Investigation of the Impact of Commercial Building Envelope Airtightness on HVAC Energy Use, proved the link between HVAC energy consumption and building airtightness. In three sample buildings, a continuous air barrier reduced air leakage by up to 83 percent, gas use by 40 percent and electrical use by 25 percent (Read NIST Report Summary PDF).
Achieving impressive air leakage reductions and energy savings is possible in most of North America’s existing buildings. In many instances breaks in the continuity of a building’s envelope are glaring. The aggregate size of the “hole” in many buildings is larger than a standard garage door.
HVAC equipment will compensate for a garage door-sized hole in the building envelope by running longer and using more energy. By appropriately connecting building assemblies to create an airtight building envelope we will reduce the unwanted air leakage, control air as intended and the save 14 % - 18 % of heating and cooling expenses.
