![]() On The California Energy Commission (CEC) unanimously approved the revision of the state's energy efficiency standards for new homes and commercial buildings. State of California Incorporates RESNET Air Tightness Testing Provisions Into Revised Energy Code For more details on this requirement, click here (see Chapter 13). Seattle Energy CodeĪll Buildings require a whole building test conducted but the code requirement does not require the building to pass a prescribed value. State & City Requirements for Whole Building Testing Washington State Energy Codeīuildings over five stories require a whole building test but the code does not require the building to pass a prescribed value. For more information on this research, click here. As part of this study, they will be conducting whole building air leakage tests on 20 buildings in Winnipeg and southern Manitoba. RRC will be conducting research on improving the energy performance of buildings. In 2012, Red River College received financial support through the Natural Sciences and Engineering Research Council (NSERC) along with funding and in-kind support from Manitoba Hydro. ATTMA - Measuring Air Permeance of Building Envelopes (Non-Dwellings)įor more resources on whole building testing, please visit the Whole Building Design Guide (WBDG), a program from the National Institute of Building Science (NIBS) website at Red River College - Applied Research on Whole Building Air Leakage.ATTMA - Measuring Air Permeance of Building Envelopes (Dwellings).ASTM E1827 - Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door.ASTM E779 - Standard Test Method for Determining Air Leakage Rate by Fan Pressurization.ISO 9972:2006 - Thermal performance of buildings - Determination of air permeability of buildings - Fan pressurization method.The United States Army Corps of Engineers Air Leakage Test Protocol for Building Envelopes. ![]() CAN/CGSB 149.15 - Determination of the Overall Envelope Airtightness of Buildings by the Fan Pressurization Method Using the Building's Air Handling Systems.There are many standards worldwide that detail how to perform this test, some of these include: The only requirements for whole building testing are in the State of Washington, the United States General Services Administration and all United States Army Corps of Engineers projects. Please contact your local energy utility for any incentive programs they may have which may include a blower door test.īuilding testing is not a mandatory test prescribed in building codes for commercial buildings, but a performance-based option that many designers are requiring. There are other non-code related incentive programs in the Canadian market for blower door testing including the R-2000 Program and the EnerGuide Rating System from Natural Resources Canada. The only Canadian jurisdiction which requires blower door test as part of a code requirement is the City of Vancouver as part of their "Green Building Strategy" for one and two-family homes as part of the EnerGuide Rating System Audit. Air leakage of the envelope can be a quantitative value which can affect the durability of the building envelope, and energy efficiency and comfort of the entire building or house. The test measures air leakage rates through a building envelope under controlled pressurization and depressurization. Air tightness testing is a process in which the building envelope is tested to quantify the air tightness.
