The impact of heat gain schedules on summer overheating in typical insulated dwellings

Abstract

Summer overheating is usually caused by a combination of factors, such as building location, orientation, fabric, ventilation and occupancy behaviour. People by their behaviour influence overheating through the internal heat gain mode and window opening ventilation mode. The article describes several types of occupancy profiles according to their behaviour taken from the literature: the profile of the worker, the child, the pensioner and the adventurer. From them, it is possible to disable the heat gain schedule for the whole household or apartment house. Heat gains from appliances are updated according to the modern lifestyle and current household appliances. The effect of heat gains in combination with other factors, which caused overheating, is further evaluated through the building simulation program.

The Impact of Ventilation and Shading Control on the Result of Summer Overheating Simulation

“…That means this is not an example of modern solar architecture with large glazed areas. The internal heat gains schedules correspond to the schedules previously published in previous works [25]. These were relatively higher values of profits (from people and facilities), which represented active living of the space by a family of 4 (2 adults and 2 children).…”

“…The windows were considered with low-E triple glazing with a glass U-Factor value of 0.9 W/m 2 •K and a total solar heat gain coefficient (SHGC) of 0.51 (-). Most of the windows were to the west direction oriented.The internal heat gains schedules correspond to the schedules previously published in previous works[25]. These were relatively higher values of profits (from people and facilities), which represented active living of the space by a family of 4 (2 adults and 2 children).…”

“…Another important reason is the creation of data sets for the comparative case studies, HAM simulation validation of measurement etc. In this area of research, department has long-term experience [5][6][7][8].…”
