The IEA Task 13 Advanced Solar Low-Energy Houses of the
International Energy Agencys Solar Heating and Cooling
Programme was established to promote international
co-operation in the design testing and use of buildings
and components that make use of solar energy. The
objective is to minimise the amount of purchased energy
and at the some time to achieve a good indoor climate.
The Finnish IEA Task 13 demonstration house, IEA5 Solar
House, has been designed within the framework of the
international collaboration. The objective of the IEA5
Solar House is to minimise the energy consumption using
present technology or new technology on recognized
construction principles in Finnish climatic conditions.
In this report the building process has been presented.
The energy saving solutions of the house and the
designing process has been reported.
The objectives set for the building envelope were well
achieved. The airtightness of the envelope was 0.87 ACH
at 50 Pa pressure difference. According to results from a
short time test, the building heat loss coefficient is 85
W/K which is 10 - 15 % lower than calculated valve. The
estimated yearly consumption of purchased energy is 27
W/m² which is about 10 % of the consumption of a typical
Finnish small house.
