Application significance and present situation of green energy-saving technology

green energy saving is the development direction of modern building engineering. The ultimate goal of green building energy saving is to reduce the utilization of energy and resources through reasonable design, thus reducing the pollution caused by resource exploitation and utilization. Can use itself and the surrounding environment to form a harmonious and unified organic circulation system, can be in harmony with the surrounding environment, and realize the sustainable development of modern architecture. In this paper, the low-carbon energy-saving design of green buildings is selected as the research object. On the basis of briefly introducing the design principles, the necessary discussions are carried out from the aspects of lighting, ventilation and environmental design, aiming at effectively promoting the related work.
