Green roofs offer environmental benefits, which can improve urban elasticity to climate change. In European countries, 36% of total greenhouse gas emissions is assign to the buildings. Commercial buildings for heating, cooling and lightening purposes consume a significant portion of energy. Energy saving, thermal insulation, shading and evapotranspiration features highlight the key role of green roofs in overall thermal performance of buildings. Green roofs and facades are key solutions to moderate building related energy consumptions and greenhouse gas emissions. The study based on literature survey with Library, seminar papers, Journals, Internet reports and research society. The main advantages of green roofs are their energy savings and environmental benefits. Green roofs become financially advantageous compared to flat roof constructions with only uncertain reductions in their current installation cost. Many policy makers and governments take significant measures to systematical reduce carbon emissions and energy use in buildings.
