Chinese National Standards for Application of Solar Thermal Technology in Civil Buildings

In building energy consumption, water heating, space heating and air-conditioning account for a large proportion. Chinese government has been released about four national standards for the application of solar thermal technology in civil buildings, covering aspects of solar water heating, solar space heating and solar air-conditioning, to regulate the design, installation and acceptance of solar thermal systems, so as to ensure the project quality. This paper briefly introduced common features of these four national standards as well as their main contents, individual features and particular function for each standard.
