Abstract
In South Korea, the evaluation criteria for installing shading devices are defined by regulations, but the standards of design methods are not clearly established. The installation of shading devices has become mandatory for some public buildings due to revised regulations. Therefore, a design of horizontal shading device is required, and indoor environmental problems which may occur due to their installation should also be taken into consideration. This research aimed to propose a design which takes into account the energy consumption which may occur if the horizontal shading device is installed and suggests an improved design method of horizontal shading devices when they are installed. Consequently, it was confirmed that as the protrusion of the horizontal shading device becomes longer, the incoming daylight is reduced and the indoor intensity of illumination becomes lower, and thus more lighting energy may be consumed in a room where the shading device is installed than in the one where it is not. Therefore, annual energy consumption was calculated by applying the lighting control and it was found that the total energy consumption decreased by the reduction of air-conditioning and fans and lighting energy consumption.
Highlights
In 2013, the government of South Korea revised the “Framework Act on Low Carbon, Green Growth” in order to reduce such energy consumption, thereby establishing the requirements for composition of green architectures
By these results of analysis, this paper proposed an elementary chart of design of horizontal shading device installation
The same results were obtained for west and south windows, and the installation of the horizontal shading device blocked the incoming solar radiation which increased the cooling load of the room and made it possible to get the Energy Performance Index scores
Summary
In 2013, the government of South Korea revised the “Framework Act on Low Carbon, Green Growth” in order to reduce such energy consumption, thereby establishing the requirements for composition of green architectures. The horizontal shading device has a simple concept and easy installation procedure, considered to be efficient in energy saving in building heating and cooling energy consumption. The calculated figure of the protruding length of each horizontal shading device was applied, the indoor energy consumption was calculated by means of simulation, and the results were analyzed. By these results of analysis, this paper proposed an elementary chart of design of horizontal shading device installation
