INVESTIGATION OF LIGHTING, DAYLIGHTING AND SHADING DESIGN OPTIONS FOR NEW CONCORDIA UNIVERSITY ENGINEERING BUILDING

Athanassios Tzempelikos, Andreas Athienitis

Abstract: This paper presents a simulation study of façade design options for the new Engineering building of Concordia University in Montreal. Optimal shading and daylighting configurations are determined, based on hourly illuminance distributions calculated with a radiosity-based simulation method. Simulations include the estimation of the performance of motorized shading devices in conjunction with controllable electric lighting systems using two lighting control options. Hourly simulations were also performed for an atrium façade facing southwest. Other daylighting concepts are also considered, such as natural illumination of corridors adjacent to the perimeter offices. Simulation results showed that, using an optimum combination of shading devices and controllable electric lighting systems, the energy savings in the perimeter spaces due to reduction in electricity consumption for lighting may exceed 80%. Moreover, the illuminance conditions are significantly improved, resulting in a high quality and pleasant visual environment.
