After more than 10 years of war, Syria is experiencing a severe energy crisis, particularly in the electricity sector. This has led residents to turn to solar energy as an alternative to the public grid by installing solar panels on buildings. However, their integration into the built environment poses a problem for the architectural quality of the city’s urban landscape. Due to the individual and random use of this energy, roofs become an overlapping network of solar panels (photovoltaic and thermal), regardless of the visual deformation they cause, in addition to the lack of regulations governing the distribution of these installations in Syrian cities. The key role of building-integrated solar active systems in the architectural design of buildings is increasingly becoming evident, especially in Syria where high values of annual solar energy are recorded. This chapter provides an overview of the current status of solar energy use in Syria and its impact on the urban landscape of cities. It discusses solar energy and building integration technologies and their applications in residential buildings and proposes solutions that allow these systems to be accommodated in the design of the fifth residential façade as a step toward sustainability within Syrian residential architecture. The research also proposes a process for planning the integration of a solar energy system into residential buildings in Syria.
