Abstract

The paper describes the first results from a large Danish project regarding measurements of energy performance and indoor environmental quality in 10 Danish Passive Houses. The project includes both qualitative and quantitative analyses. This paper describes the first results from the quantitative part.

The house considered in this paper has an air change rate (ACR) of 0.34 h-1 and the results from the first few months of measurements show excellent results when relative humidity (RH) and CO2-levels are considered. When the temperatures are assessed problems with slight overheating are found. One of the main reasons for this is the low solar angles during spring combined with the lack of solar shading and a low ACR. Solar shading and increased ventilation should be able so solve the problem. The energy consumption for room heating show a very low consumption as expected whereas the energy used for heating domestic hot water is very similar to conventional houses.
