One of the more efficient and cost effective passive methods for reducing the cooling (heating) load of a building is with the use of solar insulating materials. CSEM-UAE has performed a theoretical study of different cost-effective and thermally efficient solutions regarding the solar insulating materials for buildings. The preliminary laboratory scale calorimetric study on solar insulating materials showed that energy savings of 20-30% can be obtained with different solar insulating and reflective materials. To perform a real outdoor test of the savings obtained with solar insulating materials, a solar calorimetric test facility has been designed. The present design is aimed at determining the energy savings of different measures with similar indoor conditions, with and without solar insulating materials for the same ambient conditions. The design and simulation results of the test facility with various solar insulating materials are presented in this paper.
