I. INTRODUCTION Construction sector consume our natural resources and have a wide range of environmental and social impacts. These environmental concerns are a key driver behind the sustainable design movement. The built environment makes a significant contribution to environmental degradation. Buildings including construction, operations and deconstruction impacts, use approximately 15% of the world’s fresh water resources, 40% of the world 's energy and produce approximately 30% of the world 's greenhouse gas emissions. The analyst forecast global market to grow at a CAGR of 9.6% during the period 2016-2020.To prevent the worst effects of global climate change and minimize other negative environmental impacts, it is therefore important to address the environmental impacts of buildings. In fact, energy efficiency reductions in the construction and operation of buildings, offers one of the single most significant opportunities to reduce man’s impact on climate change. Globally most of the energy used is produced from fossil fuels like coal, oil, natural gas, and a direct consequence of using these fuels is that greenhouse gasses are released into the atmosphere, with one of the most significant being carbon dioxide (CO2). These gasses emitting infrared radiation, contribute to global warming and climate change. In response to this threat, governments across the world have committed to reducing greenhouse gas emission and increasing renewable energy production. The
