HI-85-03-1 — Fan Pressurization of Buildings: Standards, Calibration, and Field Experience
- Comments Off on HI-85-03-1 — Fan Pressurization of Buildings: Standards, Calibration, and Field Experience
- ASHRAE
The fan pressurization method has been widely used by groups working with building retrofits and with new construction to evaluate the air tightness of building envelopes. To ensure uniformity in the testing method ASTM Standard E779-81 was developed. This standard is reviewed with commentary on practical aspects of its application. Calibration of the fan pressurization systems, often referred to as blower doors, will also be discussed, pointing out where calibration difficulties have arisen and the implications on field inspections. Use of fan pressurization together with infrared scanning is one-of the best methods to pin-point air leakage sites in building envelopes. The applications of such methods in a variety of buildings – will be discussed in order to demonstrate the utility of the methods in the evaluation of building tightness, including seasonal variations; effectiveness of envelope sealing; and the location of problem areas in the building envelope.
