Résumé
The sun provides more energy in one hour than all of humanity uses, in all forms in a single year. We need this solar energy to provide solution to energy problems. This thesis investigates the difference between passive, active and hybrid solar energy systems, to develop design strategies for optimally net zero energy solar homes. Optimal design refers to the integration of renewable energy technologies (mainly active and passive solar energy) with a high-quality building envelope as well as efficiency and conservation measures, to achieve substantial reductions in energy consumption and afford home’s need by PV systems. Effective implementation of these strategies requires an integrated design approach. Furthermore, solar passive and active concepts must be an essential part of the integrated design of a home to improve energy performance and ensure occupant comfort. The thesis reviews how solar energy can be used in lighting, heating, domestic hot water and cooling in a passive way and how and also in electricity production. Design and operation strategies of a Three case studies, international projects, are presented. Features of these homes include passive solar design, a building-integrated photovoltaic system. It was useful to review design approaches and how these homes could achieve energy efficiency, and how the designer used solar energy to afford nearly all the energy needed with applicable designed solar homes. Also the thesis highlights the situation in Egypt in dealing with solar energy in homes scale. This thesis investigates the strategies for optimally or near-optimally designed solar homes. Optimal design refers to the integration of renewable energy technologies (mainly active and passive solar) to achieve balance between energy consumption and electrical energy produced by PV. Furthermore, solar energy design strategies must be an essential part of the integrated design of any home to improve energy performance and ensure occupant comfort. Weather forecasts along with an understanding of the building’s thermal dynamics enable predicting and managing loads and solar energy availability. Design strategies of a typical home, the simulation model home, are presented. Features of this home include passive solar design, a building-integrated photovoltaic/thermal (BIPV/T) system. In this simulation, this thesis reviews how can the designer make some changes in orientation, building envelope, opening size, insulation and shading, to reduce energy consumption and in the same time achieve human comfort. After reducing energy consumption, we still need integrated building photo voltage BIPV system to satisfy electrical energy needs, which can be used in devises operation and also to have light at night
