3.4 Testing of a building indoor environment during the warm period 85 Based on the results of the simulation we can affirm that: • Intensive cooling with outside air at night, protection facade shields and window shades located on the internal side do not secure thermal comfort during more than half of the warm period, • The window shade with the high reflection surface mounted outside and near the fenestration guarantees the best protection of gains resulting from solar radiation during the summer. First of all, the relatively high inside operate air temperature is the result of a large fenestration area of each segment and also of internal heat gains. Apart from that, the high thermal insulation of the windows limits heat transfer when the outside air temperature is lower than the inside temperature. We can observe the lowest level of thermal comfort in apartments OG2 and OG3. The PMV index reaches about 3 in June and September. Comparatively good conditions of comfort are present in segments OG1 and OG4. Due to effective external shading devices and night cooling, the internal air temperature stays below 28°C. The next simulations were conducted to compare the designed fenestration area with the optimal windows area in summer conditions. Results of the analysis are presented in the figures below.
