q L is the volumetric leakage airflow rate expressed in m 3 h −1; C L is the air leakage coefficient expressed in m 3 h −1 Pa −n; ∆p is the pressure difference across the building envelope expressed in Pa; n is the airflow exponent (0.5 ≤ n ≤ 1) This law enables to assess the airflow rate at any pressure difference regardless the ...
A typical graph of air leakage vs. pressure (in French) Building leakage is described by a power law equation of flow through an orifice. [20] [21] The orifice flow equation is typically expressed as = =Airflow (m 3 /s) = Air leakage coefficient
Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
The relationship between pressure and leakage air flow rate is defined by the power law model between the airflow rate and the pressure difference across the ductwork envelope as follows: q L =C L ∆p n. where: q L is the volumetric leakage airflow rate expressed in L.s −1; C L is the air leakage coefficient expressed in L.s −1.Pa −n
NFRC labels provide performance ratings for such products in five categories: U-value, Solar Heat Gain Coefficient, Visible Transmittance, Air Leakage, and Condensation Resistance. [1] This allows architects, builders, code officials, contractors, home owners, and specifiers to compare the energy efficiency among products, and determine whether ...
The rising warm air reduces the pressure in the base of the building, drawing cold air in through either open doors, windows, or other openings and leakage. During the cooling season, the stack effect is reversed, but is typically weaker due to lower temperature differences.
