5.1 Although a number of different methods have been used to assess backdrafting and spillage (see NFPA 54, CAN/CGSB-51.71, and 1-4)6 a single well-accepted method is not yet available. At this point, different methods can yield different results. In addition, advantages and drawbacks of different...
5.1 Air leakage accounts for a significant portion of the thermal space conditioning load. In addition, it affects occupant comfort and indoor air quality. 5.2 In most commercial or industrial buildings, outdoor air is often introduced by design; however, air leakage is a significant addition to...
This Standard applies to fans and ventilation equipment that are a) cord-connected, rated at not more than 250 V; b) permanently connected to supply circuits of 600 V and less, single-phase or three-phase; and c) used in accordance with CSA C22.1, Canadian Electrical Code, Part I. -...
