The effectiveness of different configurations of vertical louvers on energy performance in office buildings in Cairo

Abstract EN

This paper aims to identify the effect of solar control devices - vertical sun louvers - in an open-plan office space with a western full glazing facade in order to test the optimization level of energy performance within office buildings in Cairo through controlling the different configurations of the vertical louvers.

An action experimental research is used to investigate annual cooling loads (representing energy performance).

Environmental simulation software (Design Builder for thermal and energy + for analysis) are used during this testing research to investigate the effect of changing rotation angle of vertical louvers on annual cooling loads.

It is concluded that energy performance can be enhanced while applying small and large values of rotation angles of vertical louvers.
