The IPCC's Fourth Assessment Report (AR4), provides up to date knowledge of the current state of scientific, technical and socio-economic aspects of climate change. It consists of three Working Group (WG) Reports and a Synthesis Report. "Climate Change 2017: The Physical Science Basis" is the result of the work of IPCC's Working Group I and assesses the physical scientific aspects of the climate system and climate change.
Since the world’s buildings account for a large share of the global final energy use and greenhouse gas (GHG) emissions they have a key role to effectively address climate change. Complimentary, under a scenario with aggressive adoption of energy-efficiency measures, cost-effective energy efficiency could substantially cut projected baseline growth in carbon emissions from energy use in buildings.
