Excel Calculation Tool

According to ISO 9972, a natural pressure difference of 5 Pascal must be maintained for a standard-compliant BlowerDoor measurement. To estimate the natural pressure differences at the building envelope due to thermal effects, we have developed a great Excel calculation tool for you and made it available in the

Wind effects on the building envelope

How do the forces of wind affect the building envelope? What differences can be observed on one or more of the outer walls? How can the measurement setup for long-term measurements looks like? We have pursued these questions and have compiled them for you in a short

Get the TEC Auto Test App now!

The TEC Auto Test app allows you to wirelessly connect with a DG-1000 oder DG-700 pressure gauge to conduct an automated airtightness test of a building according to ISO 9972.

How to measure very airtight buildings

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 measuringprocedure and patience. In her article Dipl.-Ing. Stefanie Rolfsmeier explained how the measuring procedure looks like in such cases and gives recommendations on how to achieve reliable and repeatable measurement results. The article is available to our customers in the
