Through the application of technology in buildings, we can save over 50 of a building’s energy consumption and demand. The International Energy Agency’s Technology Roadmap for Energy-efficient Building Envelopes states that, The quality and energy efficiency of building envelopes are the most important factors that affect the energy consumed by heating and cooling equipment.4. The roadmap concludes with a set of near-term actions that stakeholders will need to take to achieve the roadmap’s vision. Donovan Energy provides best-in-class, proven technologies, solutions, and strategies to reduce energy consumption in buildings. The International Energy Agency (IEA) has released a report titled Technology Roadmap: Energy Efficient Building Envelopes, which illustrates how improving primary thermal barriers of buildings can cut buildings total energy consumption by nearly 20. ![]() It finds that urgent action is required if the building stock of the future is to consume less energy and result in lower CO2 emissions. The Global Roadmap for Buildings and Construction sets out targets and timelines towards achieving zero-emission, efficient and resilient buildings and construction between 20. The Energy-Efficient Buildings: Heating and Cooling Equipment Roadmap sets out a detailed pathway for the evolution and deployment of the key underlying technologies. It is based on the International Energy Age. Most of these technologies – which include solar thermal, combined heat and power (CHP), heat pumps and thermal energy storage – are commercially available today. This webinar presents detailed strategies and actions for transforming the way buildings are constructed by 2050. Energy-efficient and low/zero-carbon heating and cooling technologies for buildings have the potential to reduce CO2 emissions by up to 2 gigatonnes (Gt) and save 710 million tonnes oil equivalent (Mtoe) of energy by 2050. Currently, both space heating and cooling, as well as hot water, are estimated to account for roughly half of global energy consumption in buildings. Residential: R-10 VT>0.6 Commercial: R-7 VT>0.4 Comparable weight and thickness to currently installed base. Projected installed cost premium over 2010 installed base: Residential: 6/ft2 Commercial: 3/ft2. ![]() The roadmap will combine efforts in such fields as energy efficient building shells, lighting, windows, heating and cooling and sophisticated controls. 2025 Cost Target 2025 Performance Target. Buildings account for almost one-third of final energy consumption globally and are an equally important source of CO2 emissions. Energy-efficient technologies and practices reduce energy consumption, resulting in lower utility bills and operational expenses. Recent developments include completion of the Building Envelope Technology Roadmapand implementation of the Window Industry.
