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.
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.
Building envelope design is a specialized area of architectural and engineering practice that draws from all areas of building science and indoor climate control. [2] The many functions of the building envelope can be separated into three categories: [3] Support (to resist and transfer structural and dynamic loads)
In heating, ventilation, and air conditioning (HVAC), testing, adjusting and balancing (TAB) are the three major steps used to achieve proper operation of heating, ventilation, and air conditioning systems. TAB usually refers to commercial building construction and the specialized contractors who employ personnel that perform this service.
At the time, it was known as Arkansas Industrial University, and did not have a separate engineering college. The College of Engineering was established in 1913. In 2006, a solar boat built by University of Arkansas mechanical engineering students and electrical engineering students won the Collegiate World Championships. [2]
In addition, in May, 2012, USACE issued a new Engineering and Construction Bulletin in collaboration with the Air Barrier Association of America, outlining Army requirements for building airtightness and building air leakage testing for new and renovation construction projects. [23]
