Door Fan Test (Blower Door) for energy saving of building.(Energy Rating)
Door Fan Test (Blower Door) for buildings is intended to characterize the air permeability of the building envelope or parts thereof. It can be used:
a) to measure the air permeability of a building or part thereof for compliance with a design airtightness specification;
b) to compare the relative air permeability of several similar buildings or parts of buildings;
c) to identify the leakage sources; and
d) to determine the air leakage reduction resulting from individual retrofit measures applied incrementally to an existing building or part of building.
