Integrating Solar Photovoltaics in Residential Buildings: Towards Zero Energy Buildings in Hail City, KSA

In recent years, most cities have faced great demand for electricity supply due to rapid population growth and industrialization. Supplying sufficient electrical energy, while reducing greenhouse gas emissions, is one of the major concerns policymakers scientists all over world. Saudi Arabia, local authorities are increasingly aware necessity environmental impact nonrenewable energy by exploring alternative sustainable sources improving buildings’ efficiency. Recently, building-integrated photovoltaic (BIPV) technology has been regarded as a promising generating instantaneous buildings. To achieve substantial contribution regarding zero buildings, solar should be widely used in residential buildings within urban context. This paper examines how an appropriate model integrating photovoltaics on rooftop Hail city provide sources. The estimated areas city, utilizable PV application were calculated. Using PV*SOL simulation software, performance ratio system efficiency, well annual output several tilt angles, determined presented. amount expected when using effective roof area was also CO2 emissions that could reduced result estimated. results show significant suitable which exceeds 9 million square meters. On other hand, efficiency affected angle module, where increases with higher angle, this module temperature, where, decrease temperature its increases. indicate 30° produced highest whereas 75° records smallest although it achieves best possible There from use rooftops Hail, there reduction emissions. It research would develop innovative building design strategies specifications allowing better climate well.
