Building Airtightness


An airtight building has several positive impacts when combined with an appropriate ventilation system (whether natural, mechanical, or hybrid):

  • Lower heating bills due to less heat loss, with potentially smaller requirements for heating and cooling equipment capacities.
  • Better performing ventilation system.
  • Reduced chance of mould and rot because moisture is less likely to enter and become trapped in cavities
  • Fewer drafts and thus increased thermal comfort 

A number of studies have shown substantial energy savings by tightening building envelopes.


So how do we know or measure the airtightness of the buildings in Cyprus?

The answer is with the blower door test which is a machine used to measure the airtightness of buildings.

It can also be used to measure airflow between building zones, to test ductwork airtightness and to help physically locate air leakage sites in the building envelope.

Blower door test in Cyprus is a well-known procedure which is applied by many leading engineers and architects who trust our company’s expertise in performing these tests.
