The present thesis is directed to the analysis of the indoor environmental conditions and the energy performance of two energy-efficient apartment houses in Vienna. The first of which is a passive house and the second one is a low-energy house. Both are located in Dreherstrasse, Vienna and were developed simultaneously by the same companies. Building materials and dimensions are comparable; floor plans deviate insignificantly. The main difference between the two blocks (other than the higher degree of thermal insulation in the passive building) lies in the ventilation system: passive buildings deploy controlled ventilation, whereas the low-energy buildings rely mostly on user-operated natural (window) ventilation. Thus, it is reasonable to compare these two buildings with respect to indoor climate and energy performance without the influence of paramters which are difficult to be introduced to the calculations such as different wall materials or different weather situations.

From all factors affecting indoor climate temperature [...]
