Zero Energy and Low Water Schools: Case Study- Building of Garaboulli Engineering Faculty-Libya

The current paper presents the design methodology for reducing the water consumption to reach a zero energy building. The building of the Garaboulli Engineering Faculty (GEF), Libya was chosen as a case study. The required energy will be supplied by renewable energy. In order to meet the required loads, solar energy is used in the design to generate heating, cooling, and electric power by using different techniques such as solar thermal collectors and photovoltaic panels. Moreover, rain water is used as a source of water supply for the building. To reach the low water and Zero Energy aims, different techniques such as recycling of greywater and solar cooling were adopted. Finally, the proposed system will be feasible for a long term of operation.
