Comparison of various measures to reduce the temperature in the attic room in summer

Popis výsledku v původním jazyce

This paper presents the results of the comparison of various measures to reduce the indoor air temperature in the attic room in summer. The building with attic rooms in Brno in the Czech Republic was chosen for this research. The building was modeled in the DesignBuilder software and compared with the measured results in the given period to optimize the model. After verifying the correctness of the model, six different alternatives of shading measures were one by one added in the model, and simulations were run. One alternative changed the conventional glazing to the electrochromic glazing system. In two alternatives, the conventional clay roof tiles were changed to innovative types of roof tiles. The first roof tiles are cool light-colored clay roof tiles with a high albedo, and the second ones are ventilated roof tiles with 3 cm of an air gap. In the last three alternatives, different indoor and outdoor shading devices were added to the skylight. For this case, indoor slatted blind, indoor shade roll, and outdoor shade roll were used. The results of each alternative were compared with the results of the simulation without any measure. The chart shows the different temperature course of each alternative during the given period. The main indicator of the effectiveness was the reduction of peaks of indoor air temperature in the attic room in the given period. The results were compared, and the best measures of tested ones are the outdoor shade roll and the electrochromic glazing system. In conclusion, the results of all alternatives are discussed.
