Application of Passive Building Technology Based on Embedded Pipes in Walls

In China, there is an uneven distribution of energy resources, and building energy consumption remains high, necessitating urgent energy conservation and emission reduction. In recent years, with the continuous development of passive buildings in our country, the attention to building energy-saving technology has increased. Therefore, a passive building plan that combines wall pre-buried piping with a ground-source heat pump system can replace the traditional heating and cooling systems. This dual-system approach can reduce the heating index by 8 W/m2 and the cooling index by 4 W/m2 during the heating and cooling periods, respectively, bringing building energy consumption to a lower level. In the context of increasing concern over energy and environmental issues, this provides a reference for the development of passive buildings in China and the realization of zero-carbon goals.
