The development of human society is a non-stop gear, and the way we use energy is about the future. How to use resources reasonably and effectively is the pressure we face. The increase in population is the problem of resource allocation—insufficient inventory of traditional energy sources. Economic development is a double-sided blade, and ecological environmental protection is our focus. Research and development of new energy and renewable energy is a way to block dependence on traditional energy sources. It is the inevitable way for human beings to coexist harmoniously with ecology in the future. The development of the construction industry has also brought about a greater proportion of energy consumption. Building heating, ventilation, air conditioning and lighting account for about one-third of the total energy consumption. The carbon dioxide emissions of the construction industry account for more than half of the total emissions, which has a great impact on the environment. The broad definition of building energy conservation is proposed, and the significance of using new energy to building energy conservation is expanded from the perspective of macro environment, including the use of integrated energy, solar energy, and energy islands to achieve zero energy consumption in building energy conservation. The construction has effectively promoted the development of zero energy consumption in terms of the life cycle and environmental protection.
