Building and ductwork airtightness in the Czech Republic: national trends and requirements

The AIVC is preparing a series of VIP on national regulations and trends in airtightness for various countries (numbered VIP 45.XX), detailing for both building and ductwork airtightness: 

• the national requirements and drivers (regulations, incentives, justifications and sanctions)
• whether it is taken into account in the energy performance calculations and how;
• the test protocol (testers qualifications, national guidelines, requirements on measuring devices);
• the tests already performed and whether there is a results database;
• key documents.

This presentation focuses on the airtightness trends in the Czech Republic. More information can be found in VIP 45.3.
