[AIVC, Air infiltration and ventilation glossary, 1992]:building airtightness levels can be measured by using a fan, temporarily installed in the building envelope (a blower door) to pressurize the building. Air flow through the fan creates an internal, uniform, static pressure … Continue reading →
[AIVC, Air infiltration and ventilation glossary, 1992]:a blower door is fitted to a building, induced air flow through the fan creates an artificial, uniform static pressure within the building. Internal and external pressure taps are made, and a manometer is … Continue reading →
[AIVC, Air infiltration and ventilation glossary, 1992]:the building’s own mechanical ventilation system can be used to provide the required pressure differential from within. The supply fans are operated while al1 return and exhaust fans are turned off, and all return … Continue reading →
