THE EFFECT OF WINDOW POSITION AND WINDOW SIZE ON THE ENERGY DEMAND FOR HEATING, COOLING AND ELECTRIC LIGHTING
The amount of sunlight and daylight through the facade is a key factor in new facade design. Designing a new facade, based on the idea that a facade should be able to function and perform mostly autonomously (i.e. requiring as little input such as warm/cold water, air and electricity from the building as possible), the amount of sunlight and daylight through the facade influences the yearly energy demand for heating, cooling and electric lighting. In this paper it is shown that it is possible to calculate the yearly energy demand for heating, cooling and electric lighting as a function of window position, window size and window shape for an office environment in the Netherlands. This result should enable the design of improved autonomous facades for office buildings.
