Sentences with phrase «controlling air leakage»

Clearly, everybody agrees that controlling air leakage is of paramount importance.

In mixed climates, building envelopes are constructed in an airtight manner to control air leakage openings, to expedite air pressure control (depressurization of the building envelope above grade during the heating season, pressurization below grade to control ingress of soil gas and other pollutants, and pressurization of the building envelope during the cooling season) and to facilitate the dehumidification of indoor air during the cooling season, thereby limiting interior moisture levels.

Not exact matches

Let the EPA know that you support expanding the regulations issued pursuant to Section 608 of the Clean Air Act to control of leakage and venting of HFCs.

I support the EPA in its movement toward expanding Section 608 of the Clean Air Act to control leakage and venting of HFCs.

Moisture movement by air leakage (the exfiltration of interior moisture - laden air during heating periods and the infiltration of exterior moisture - laden air during cooling periods) is controlled by limiting air leakage openings, controlling the interior levels of moisture during heating periods by utilizing controlled ventilation (dilution by air change) combined with source control (direct venting of clothes dryers as well as the use of subgrade vapor retarders under concrete floor slabs and bath and kitchen exhaust systems), controlling the interior levels of moisture during cooling periods by utilizing the dehumidification capabilities of mechanical cooling systems, and limiting controlled ventilation to minimum values established by indoor air quality concerns.
