is of great importance in the building field toreconsider the building structure and exploit
renewable energy systems, which can minimize theenergy expenditure and improve thermal comfort.
Solar energy is abundant and clean; it ismeaningful

forconventional energy. Solar energy therefore has animportant role to play in the building energy
system. Recently, solar water collectors haveundergone a rapid development; they are installedwith the main purpose of preheating domestic hotwater and / or to cover a fraction of the spaceheating demand. However, this application mainlyfor obtaining hot water through solar energy is notvery consistent with the order of nature. In winter,
it is convenient to combine hot water system withspace heating system just through increasing thecollector area. Whereas, for summer with highsolar radiant intensity and high ambient airtemperature, the demand for air-conditioning andrefrigeration is in preference to hot water. Basedon this background, the research on solar thermaltechnologies, especially solar cooling technology
will be introduced.[1] The main contents include 1)
design of solar thermal systems, 2) performance ofsolar thermal systems based upon experimental
investigation, 3) cases of solar thermal systems in
