Potential of solar shading solutions for reducing overheating while maintaining acceptable levels of daylight in a refurbished Danish apartment building from the period 1950-1970

Abstract

Refurbishment of existing buildings is essential for significant energy savings. Addition of thermal insulation and tightening of the envelope lead to energy savings for heating, but a limited infiltration can cause elevated indoor temperatures during periods with high solar radiation. An excess indoor temperature has been proven to negatively affect health, well-being and productivity.
The paper presents a study focused on the potential of solar shading solutions to reduce overheating without compromising daylight conditions in a typical Danish apartment building from 1950-1970 after refurbishment. The study used coupled thermal and daylight simulations in IDA ICE. The results show that it is possible to obtain acceptable indoor temperatures and maintain daylight levels with use of external solar shading as awning blinds and marquisolette. In case of external or internal venetian blinds, the slat angle and the blinds’ colour strongly affect the efficiency of the shading devices regarding overheating as well as the daylight condition in the rooms.
