Abstract

Appropriate shading application is considered a promising way to reduce building energy consumption. In this paper, an experiment is conducted to study the actual performance of interior blind in office building of Hong Kong. During a clear sunny day, an 8.7% reduction can be expected while the blind tilt angle is set at 90°. While the tilt angle is set at 45°, the reduction can be over 18%, the peak cooling load can also be reduced. After interior blind is applied, the difference of air status among different area within the room is also obviously reduced. The measurement result is then compared with an EnergyPlus simulation. A generally good agreement is achieved between experiment and simulation. Result indicates that in Hong Kong interior blind can significantly reduce window heat gain and maintain a more comfort indoor environment while retain the sight view of high-rise commercial building.
