Objectives:
- To measure the typical air change rates (at 50 Pa) of different recently built detached houses with massive structures and flats in multi-storey buildings, and to compare them with the results of the Moisture-proof healthy detached house study.
- To determine the typical air leakage distributions of detached houses and blocks of flats with different envelope structures (timber-framed and massive frame detached houses as well as concrete- and timber-framed blocks of flats).
- To establish critical/recommended values for airtightness of detached houses and blocks of flats while also considering energy consumption, moisture convection, pressure conditions of the building and the sense of draught.
- To develop the principles for a procedure to check airtightness.
- To give design guidelines for improving airtightness of different structures and joints.
- To determine the mechanical ventilation rate and ventilation sound pressure levels of detached houses with massive structures and flats in multi-storey buildings, and to compare them with the results of the previous stage.
- To determine the need to develop ventilation and to give instructions for achieving clean and functional ventilation, especially in multi-storey residential buildings.
- To determine the moisture production of apartments and a design value for moisture supply as a function of outdoor air temperature in flats in multi-storey buildings.
- To examine the impact of building envelope on the indoor air moisture and temperature conditions.
- To determine temperature stability during heating season and the occurrence of excessive temperatures in detached houses with massive structures and flats in multi-storey buildings.
