The impact of façade designs: orientations, window to wall ratios and shading devices on indoor environment for naturally ventilated residential buildings in Singapore

چکیده
The impacts of building envelope designs are significant on indoor thermal environment, especially for naturally ventilated buildings. Parametric façade studies were investigated for various orientations, window sizes and shading devices by using building simulation (ESP-r) and CFD (FLUENT) coupling program to predict indoor thermal environment in an accurate and quick way. Two typical weeks were selected in May and October as the representatives of dry season and raining season in Singapore. Thermal comfort was chosen to be the criteria to evaluate different façade designs. The results suggest that the increase of window to wall ratio to 0.24, indoor thermal comfort could be largely improved and 600mm horizontal shading devices are needed for each orientation in order to improve thermal comfort in further.

Nowadays, the increase of fossil fuel consumption intensifies the crucial role of architects. As buildings consume over one-third of the used energy, the society of architects is held responsible for this consumption. Therefore, the amount of energy used by a building is directly related to its design; meaning that reduction of energy consumption should be targeted at the design stage. In this ...
