Passive cooling influencing factors and formation mechanism analysis of the street space in Huizhou traditional dwellings

Received: 10 March 2018 Accepted: 1 August 2018 The passive cooling strategy adopted in the street space of Huizhou traditional dwellings boasts great ecological value. This paper probes into the influencing factors of passive cooling and the formation mechanism of these factors. It is concluded that sun-shading should be utilized and wind pressure ventilation should be suppressed in daytime to reduce the heat gain; the space interface should be utilized to boost the accumulation of cold; the thermal pressure ventilation at day should be combined with wind pressure ventilation at night to speed up radiation. Field test and analysis was adopted to probe into the influencing factors of these factors. The mutual influence between these factors helps to maintain a good thermal environment in the street space in summer. And the findings of this study may serve as guidelines for outdoor environment design of traditional residential buildings.
