Analysis of Heating Energy of Ventilation and Underground Heat Exchanger in North European Passive Houses (original) (raw)
The paper is taking under consideration the two non-residental passive house buildings built in North Europe in Estonia. The first building is a community center of village Palamuse and the second monitored building is a kindergarten "Kaseke" in Valga city. Both buildings were planned and designed according to the Austrian passivehouse standard requirements. In current paper energy consumptions of building services systems and thermal indoor climate parameters were measurements. According to these, the building services systems did not work properly and problems occured. Both buildings consumed considerably more energy in reality than indicated in energy simulations accomplished before the actual construction. Also it was discovered that the relative humidity levels in both buildings were considerably lower than recommended in Estonian standards. Besides the risk of condensation for the supply air in underground supply pipes in Nordic conditions was analysed. The analysis ...
