Blower door test results

Last year we built an energy star home for a customer and we a blower door test uses the houses air infiltration evaluate performance. A differential pressure is simply put a diagnostic tool used to measure, how much air infiltration (air leakage) occurs in a House. The blower door organization allows Tester a consistent and measurable pressure it apply, so that houses compared accurately.How can be A blower-door-works

As you can see in the photo the blower door is in an outer door installiert.Die equipment consists of a variable speed fan fan controller, adjustable door frame to seal the opening and a number of pressure gauge, the pressure difference between inside and outside the House to measure speed.

The tester then calibrated devices and set a standard pressure.In our case, the tester put pressure on 50 Pascal, we determine a ACH50 rating scanned.the ACH50 review was used as part of the energy star rating received this particular House. ACH changes per hour refers to air.

Once a print which is diagnostic measurement equipment able to the volume of air through the fan with the desired pressure pressed to measure.This is used to air exchanges per hour at a certain pressure to charge and therefore our ACH50 value.The real test takes only about 15 minutes after everything is set up.

Once the blower door test is important to understand the results what is bedeuten.Es. This article focused strictly many guidelines to the values and what they mean for your home is ACH50 results, we can for this test house erhalten.Viele States and building officials are also look the CFM/50 results as a way of determining whether a House is too narrow or too drafty.

According to the Pennsylvania housing research center the following basic guidelines for ACH50 results are:

ACH50 less than 5.0-tight HouseACH50 between 5.0 and 10.0 - moderate HouseACH50 above 10.0 - leaky House

Following a full table from your publication, ACH50, CFM/50 and ENIR policies displayed.
