Abstract:
The research in this report demonstrates that it is possible to design and construct a low-energy house with an airtight and vapour permeable envelope. To realise a moisture physically safe structure, the vapour permeable envelope mus be airtight and the water vapour diffusion resistance must be greater on the warm side of the insulation than on the cold side. Measurement and simulation results show that moistue transfer between indoor air and a porous building envelope can reduce the maximum indoor humidity in the summer by about 20% RH and increase the minimum indoor humidity in the winter by about 10% RH when the ventilation rete is near design. This is important because the titerature review presented in this report shows that decreasing the humidity by 20% RH can possibly double the number of occupants satisfied with the indoor climate.
