* The lowest temperatures are found at the glass edge seal and at the base board of the lower corners of the building. The temperatures at the base are almost one degree less than the calculated temperature. This is due to drying processes taking place in the external wall that is damp from previous years. | * The lowest temperatures are found at the glass edge seal and at the base board of the lower corners of the building.

- | There were surprisingly good results of the airtightness tests. Inspection with a building pressure test in the completed state gave a value of n50 = 0.35 h-1. No serious leaks were detected. The care taken in the case of wooden beam ceilings proved to be very essential. | + | There were surprisingly good results of the airtightness tests.
