Blower Door Testing

Blower doors allow us to determine the tightness of a building envelope. The blower door pressurizes or depressurizes the building and allows us to calculate the envelope leakage rate. If the envelope leakage rate is unacceptable the leaks in the envelope are found with thermal imaging and smoke tests. As these areas are located they can then be evaluated and repaired to provide a seal from the exterior elements and interior space.

U-Value Measuring

One Stop energy Services use state of the art technology to measure the actual u-value of a wall assembly. This becomes valuable in both the commissioning of new buildings and evaluation of existing buildings. For new construction it provides verification that the actual construction of the walls meets that which was specified. In existing buildings it allows the actual U-value to be determined and areas where the u-value should be increased. In both situations it provides the building owner with accurate and reliable data about the building construction.
