The blower-door system includes three components: a calibrated fan, a door-panel system, and a device to measure fan flow and building pressure. The blower-door fan is temporarily sealed into an exterior doorway using the door-panel system and the whole test is divided into three steps:
1、Identify Air Leaks
2、Seal the Leaks
3、Verification
After the completion of the Blower Door Test, Michael Meyer-Olbersleben, the construction airtight expert, and Christine Reumschüssel, Hamburg House architect from Dittert & Reumschüssel Architects give the Chinese media a detailed explanation about test and Hamburg House construction. By witnessing the Blower Door Test and listening to the architect and airtight expert’s explanation, it is not difficult to find out that it is the careful selection of the construction materials and strict supervision and verification of the construction process that contributes to Hamburg House’s high energy efficiency.
