The first blower door was further used to test the airtightness of the Saskatchewan Conservation House built in 1977, which was tested at 0.5 ach at 50 Pa. These early research efforts demonstrated the potential power of blower door testing in revealing otherwise unaccounted for energy losses in homes.
In 2013, Orr received "The Golden Blower Door" from Passive House North. [43] In 2013, he received a Lifetime Achievement Award from Sustainable Buildings Canada. [44] In 2015, he accepted the Pioneer Award from the Passive House Institute for the team who worked on the SCH, an international award given to trailblazers in energy-efficient ...
A third test method to determine if ductwork is leaking to the outside is to use a pressure pan, which is a register cover with a pressure tap for a hose connection. With the house pressurized (or depressurized) to 50 Pa (-50 Pa) using a blower door, a pressure gauge is attached to the pressure pan by means of a hose.
4. When construction is done, the EnerGuide advisor verifies the applied energy upgrades and performs a blower door test. 5. After the data has been collected, the home receives its EnerGuide for New Houses rating. 6. The home owner is provided an official label to display the rating on the home’s furnace or electrical box.
A blower door test can be used to test the quality of the air sealing of the building envelope. Smoke pencils can be used to detect gaps and caulking and weather-stripping can be used to improve air sealing. [10]
ANSI/AMCA Standard 230 - Laboratory Methods of Testing Air Circulating Fans for Rating and Certification establishes uniform methods of laboratory testing for air circulating fans in order to determine performance in terms of thrust for rating, certification or guarantee purposes. The 1999 version, in general, described a method to determine ...
Performance testing, such as a blower door test for air leakage, outside and total duct leakage, and mechanical ventilation testing is usually part of the rating. Confirmed, Sampled, and Threshold Ratings that are built above code requirements are registered with public databases such as the RESNET Registry [8] and the BSI Registry. [9]
An initial verification test must then be done within 30/120 days, and then a follow-up test within 10 days of that. There are additional clauses for extensions if needed. If the leak is not to be repaired, there must be a plan to retire or retrofit the appliance within 30 days, to be completed within one year.
