Now there are a lot of architectural "cold alley" design as well as thesis, but very little can be very much a definition of it!

Cold alley refers to the layout of the compound, the use of wind formation principle, the arrangement of relatively low-temperature space, creating a breeze circulation, in order to achieve the purpose of cooling, mostly seen in Lingnan residential buildings, known as its essence. Personally, I thought the effect of open cold alleys at the village level was obvious. Its energy-saving level at most equivalent to save the fan with electricity.
