description | High-rise residential estates are characterized by high floor area ratios, many floors, and similar green area ratios. Beijing is hot in summer, and shading is an important strategy to improve the outdoor thermal environment of residential estates in summer. With respect to the morphological characteristics of high-rise residential estates, three types of shading were summarized, and their relationships with air temperature were quantified and analyzed. The three types of shading are building–tree integrated shading, building shading, and tree shading. Two residential estates that can represent the morphological characteristics of high-rise residential estates in Beijing were selected for field measurements, and the cooling effects of the three types of shading were obtained by analyzing the measured data. In the same residential estate, the daytime air temperature difference between shaded and un-shaded areas can be 0.5 °C or more. It was found that building–tree integrated shading has the most significant cooling effect, with building shading and tree shading second. The cooling effect of shading decreases with time, with morning shading having the greatest effect, and afternoon shading having the least effect. |
