Development of Low-Cost Renewable Cooling and Heating Systems for Egyptian Buildings



The energy-efficient summer cooling of residential buildings in Egypt is problematic due to rising electrical costs coupled with insufficiently insulated roofs which leads to high cooling loads. With our research project we want to contribute to the development of low-cost collectors able to provide heating, cooling and domestic hot water for buildings located in hot and dry areas such as Egypt by taking advantage of long-wave radiation from roofs towards the sky. The effect is based on a lower counter radiation of the sky and can be experienced on cold desert nights. Until now this effect has never been utilized for a technical cooling process in buildings. The project could therefore launch a new technical concept for cooling houses in arid regions



NightCool is a cooperation of GUC, Faculty of Architecture and Urban Design, Department of Building Technology and Design, HFT/ ZAFH.NET University of Applied Sciences, Stuttgart, Institute of Applied Research and Centre for Sustainable Energy Technology and MEFA Energy Systems, Germany. »NightCool« is GERF funded by BMBF (Germany) and STDF (Egypt).
