With the continuous development of economy and the improvement of peoples living standard, the shortage of resources is becoming more and more obvious, which is a major problem that all human beings need to face together. As an important livelihood project, construction projects can provide great convenience for peoples daily production and life. Water is the source of life. At the same time, water supply and drainage project, as an important part of construction projects, its energy conservation and environmental protection will directly affect the overall use effect of buildings. Therefore, under the concept of low-carbon economy, it is necessary to actively carry out energy-saving research on building water supply and drainage, so as to promote the sustainable development of green and environment-friendly buildings and strengthen the construction of ecological civilization. 展开更多
