This work is part of a research project on optimization of façades of commercial buildings in the early design stage. Shading devices are utilized to control solar gains and simultaneously provide adequate daylight to the interior. A method for quantifying the effects of shading patterns on interior conditions and overall building energy performance is presented. Integrated performance indices are obtained by the continuous interaction between transient thermal and lighting simulation. Fenestration and shading systems have a major impact on visual and thermal comfort in perimeter spaces but also on energy consumption, peak loads, and possibly HVAC system sizing. Moreover, automated operation of shading devices in conjunction with dimmable electric lighting systems and HVAC system components could lead to minimization of energy consumption for lighting, heating, and cooling. An integrated approach should be followed when designing and controlling fenestration and shading systems in order to obtain optimal solutions.
