Performance evaluation of solar shading systems EVALUATED
This dissertation is composed of two parts: Part A and Part B. In Part A, a user-friendly method of how to evaluate the performance of different solar shading systems during an early design phase of a building is illustrated. The method is based on the use of WIS and BuildingCalc/LightCalc simulation tools. The solar shading systems integrating a building may be dynamically controlled and the energy and daylight performances of the building may be evaluated. A case study of a landscaped office building in which different solar shading systems were tested is presented. The building was studied for two different climates (Copenhagen and Lisbon). It is clear the difference when comparing different solar shading systems and different climates. The glass lamellas are a promising type of solar shading system that demands for more precise daylight evaluation using raytracing tools. In Part B of this dissertation, daylight measurements for glass lamellas systems performed in the experimental rooms of the Daylight Laboratory at SBi (Danish Building Research Institute) were compared with IESve/Radiance simulations. Results show that IESve/Radiance may be used to evaluate the daylight performance of glass lamellas systems in most situations.
