Blower Door Test Measurement

Understanding blower door test results.

Blower door test measurement. The excellent quality of the building envelope or the apartment envelope with air exchange rates of 0 6 h 1 and smaller are new challenges for measuring teams during the performance of the air permeability measurement which can be mastered with knowledge of the measuring procedure and patience in her article dipl ing stefanie rolfsmeier explained how the measuring procedure looks like in. A blower door test is used on buildings in order to quantify the amount of air leakage through its enclosure. Door fan test for determining of minimum hold time according to iso 14520. The blower door test.

We specialize in blower door test as well as duct work testing for new construction and existing dwellings. 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. During this test a calibrated fan is installed in an otherwise sealed door or window while all the other openings to the exterior are closed. There are three primary components to a blower door.

Blower doors consist of a frame and flexible panel that fit in a doorway a variable speed fan a pressure gauge to measure the pressure differences inside and outside the home and an airflow manometer and hoses for measuring airflow. The window and door measurement system allows you to determine the joint permeability of building components in a simple and accurate way. Last year we built an energy star home for a customer and we used a blower door test to evaluate the houses air infiltration performance. Cfm50 is the airflow measured in cubic feet per minute from the blower door fan needed to create a change in building pressure of 50 pascals.

A blower door is a machine used to measure the airtightness of buildings. 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. Blower door test results can determine the airtightness of the building and can be presented in a number of different formats.

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 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. 1 a calibrated variable speed fan capable of inducing a range of airflows sufficient to.
