Exergy analysis and life cycle assessment of solar heating and cooling systems in the building environment

► Exergy Analysis and Life Cycle Assessment of the use of Renewable Energy sources in a Building. ► The use of solar energy systems in the building sector, can lead to energy savings and lower environmental impacts. ► The solar cooling system has the greatest environmental impact followed by the system of solar space heating. ► Exergy analysis showed a relatively low efficiency for the renewable energy systems but environmental impacts are very low.
