Green Building

Environmental Executive defines green building as “the practice of (1) increasing the efficiency with which buildings and their sites use energy, water, and materials, (2) reducing building impacts on human health and the environment, through better siting, design, construction, operation, maintenance, and removal-the complete building life cycle.” “Green buildings” are called “ecological buildings” and “sustainable buildings” in European countries, “environmental symbiosis buildings” in Japan, and “green buildings” in North American countries. Performance of green building can be assessed by the international well-known methods such as BREEAM, LEED, GBTool, EEWH, and ESFGB evaluation systems. Energy-Efficient building can be made by passive energy-saving buildings, energy efficient measures, IOT applications, and integrated design process (IDP). On the other hand, the developed green construction materials and technology should be in conjunction with the principles of natural ecology, energy efficiency, waste reclamation, and human health protection. In order to achieve the carbon reduction target of the Climate Change Act, the government should formulate a zero-carbon building policy and actively implement it. The zero-carbon building can be achieved by adjusting energy use, minimizing material energy efficiency and introducing, renewable energy and combined district heating systems. In addition, it is necessary to construct the decarbonizing supply chain for carbon neutrality by integrating upstream, midstream and downstream industry players and users to ensure the net energy-saving benefits and environmental benefits of renewable building materials.
