Blower door test metodo a.

A blower door test is a machine used to calculate airflow between the interior and exterior of a structure measure the airtightness of buildings and identify spots where air is leaking through a building envelope. Reducing energy consumption due to air leakage. Tests using the blower door enable the builder remodeler to assess the tightness of a building eliminating guesswork regarding leakage and air tightness the test methodology is widely accepted and is used as one of the predictors for energy efficiency in homes. How a blower door works.

5 1 2 relation to test method e779 these test methods are specific adaptations of test method e779 to orifice blower doors. A temporary blower door equipped with a powerful fan is fitted into the frame of an. It can also be used to measure airflow between building zones to test ductwork airtightness and to help physically locate air leakage sites in the building envelope. A blower door is a machine used to measure the airtightness of buildings.

Simply put a blower door is a diagnostic tool used to measure how much air infiltration air leakage occurs in a house. When the fan is turned on it creates a pressure difference between the outside and the inside. 5 2 single point method use this method to provide air leakage estimates for assessing improvements in airtightness. A blower door test is used on buildings in order to quantify the amount of air leakage through its enclosure.

Blower door tests are performed by certified energy auditors to determine to what degree a home is airtight. This test ensures a certain level of energy performance and is often used when a project team is aiming for a performance based. These are some reasons for establishing the proper building tightness. Performing a one point test no software gather data record five 10 second average minimum baseline readings to determine the level of accuracy perform blower door test using the baseline and cfm50 functions.

Professional energy auditors use blower door tests to help determine a home s airtightness. Our energy saver 101 infographic explains the importance of a blower door test during a home energy audit. For nonorifice blower doors or for buildings too large to use blower doors use test method e779.
