The energy consumption in Algeria has a fast growing rate 1% per year. The actual reserves of natural gas and oil will be only covering the demand of the Algerian population for the next 50 years in the case of oil, and for the next 70 years in the case of natural gas as Algeria is considered the 3rd country in the world for the natural gas reserve, and in addition to that fossil fuel use is associated with significant environmental impacts such as global climate change, air pollution. Therefore the integration of renewable energies is a vital priority for the third world countries such Algeria. The aim of this paper is to apply and explore a methodology of solar integration in the urban planning in order to reach zero energy buildings (ZEB) target. To achieve the objective several analyses has to be made such as a solar potential, urban and environmental analysis.
