These days, the limited reserves of fossil and the Pollution resulting from the consumption of these fuels are a very serious threat to society and this situation put the global energy to a critical stage. Where as refer to circumstance approach around half of the whole energy and row materials in the world just belong to building as consumers. So, its very essential to enter the reproducible energy topics in order to find some solutions for climate changes and also reduce environmental pollution. This study is the result of Library Studies about the latest human achievements in the field of construction and also the impact of the photovoltaic systems on energy efficiency and analyze their role in order to reduce the environmental pollution. It seems that the use of these systems could be the solution key of environmental pollution and Increasing energy demand.
