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

Abstract

The most suitable methods for increasing the climate resistance of buildings on hot summer days are intensive ventilation and effective external shading. However, it is possible to discuss what kind of approach used, while simulating the control of these two elements in energy simulation programs, to make the result as much representative as possible. We created and compared three different control modes for this purpose. The basic mode represented models created from monitoring of habits of building users, while the second mode represented an automatic system based on sensory control. The third mode represented models that provide an early warning system against a series of hot days. They intervene in windows and blinds control for a several days in advance. The base mode using the schedules reached more than 2 °C higher maximum indoor air temperature than the two others in a direct comparison of these three systems by simulating a simple building. It also has been shown that with a relatively simple early warning system, it would be possible to replace an even more complex automatic system.

Indoor Environment, Lighting Conditions and Productivity in the Educational Buildings

“…The linear fitting (red line) is quite straightforward, as can be anticipated -humans work and learn better when they are satisfied with their indoor environment. Despite a large number of factors influencing human sensations and perceptions, thermal environment and heat transfer issues might be considered as a dominant force [15][16][17][18][19][20][21]. However, an important element is also noise [22] and future studies might be focused on this aspect due to its possible impact on the general sensations and productivity.…”

The Effect of External Blinds on Selected Parameters of the Indoor Environment of an office Building

“…The results showed that the influence of external climatic conditions [14] significantly affects the state of the indoor environment of the room under study. For buildings built in passive standard, the dominant season is not the heating season, but the cooling season with higher financial requirements for the operation of the building [15].…”

Methods of Preliminary Estimation of Total Solar Energy Transmittance (TSET) on a Sun Protected Window with Climatic Chamber and Hot Box Apparatus

“…Based on the results, it is a common partial conclusion that the tested concept of the retrofitting of the transparent system has shown a high potential in connection with the elimination of heat gain from solar radiation. However, the shading element of the window should be movable, as being fixed it would cause excessive space cooling in summer [24].…”
