SolarBau - Gebaeudethermographie - Verwaltungsgebaeude DB Hamm

Thermographic measurements and blower door measurements were carried out on two days in winter between 18 and 22 hours (inside) and between 6.30 and 12.30 (outside and inside). The outside temperature was 5 C; the first day was dry and calm while the second day was dry and windy. Strong rain had fallen in the night between the first and second day. The blower door was used for generating excess pressure or partial vacuum inside the building in order to detect leaks.SIGLEAvailable from TIB Hannover: F03B1505 / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Bildung und Forschung, Berlin (Germany)DEGerman

Bestimmung der Luftdichtheit von einzelnen Gebaeudeteilen mit Hilfe der Blower-Door-Methode - DB Hamm

The blower door measuring system consisted of a variable frame with airtight foil and integrated speed-controlled blower, a volume flow meter and differential pressure manometer. It was not possible in all cases to generate sufficient volume flow for achieving the desired pressure gradient, both in the atrium and the building as a whole. In these cases, only the volume flow for a pressure gradient was measured. The curve was approximated using typical curves, and an n_5_0 value was extrapolated which is not a real n_5_0 value but an estimated value based on the values measured for low pressure gradients. Extensive measurements were carried out on different parts of the building.SIGLEAvailable from TIB Hannover: F03B1506 / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Bildung und Forschung, Berlin (Germany)DEGerman
