An airtightness test, also known as a blower door test, is a method to check how much air escapes from a building when a pressure difference is created. This helps identify and fix leaks in the building envelope.
Why Airtightness is Important:
- Energy Efficiency:Prevents heat loss and reduces energy costs.
- Comfort: Improves indoor climate by reducing drafts.
- Health: Prevents moisture problems and mold growth.
- Environment: Contributes to lower CO2 emissions through reduced energy consumption.
- BENG: Airtightness is a crucial component of BENG standards.
Airtightness is a critical aspect of meeting the BENG requirements, specifically BENG 1 and BENG 2. Good airtightness means less heat loss due to unwanted air leaks, leading to lower energy consumption for heating and cooling. This directly impacts the energy demand (BENG 1) and primary fossil energy consumption (BENG 2).
