Interaction of Daylight Distribution And Thermal Comfort in Attic Spaces During Summer Period

Attic spaces belong among the most popular forms of housing or working. The most common reasons why people prefer this form of living are for example the efficient utilization of the land, lower costs of utility connection, better contact with environment and that it has a very positive impact on the human well-being. Thanks to the sloped window plane the daylight distribution inside of these spaces is very specific. In addition, they are critical regarding to overheating during summer period, so it is also necessary to analyse them in terms of thermal comfort. In our case, a daylight distribution on the working plane of a simple attic office room with different roof slope was determined. The thermal comfort was analysed by means of simulation program Design Builder, where the exact virtual model of the above-mentioned room was created. The aim of this contribution is to compare the results of daylight distribution above the working plane at different roof slope and orientation and to evaluate the effect of the window plane slope on the thermal comfort inside of the room during summer period.
