Hakka Tulou is a famous local earth construction, which is included in the UNESCO list of World Heritage buildings. To the best of our knowledge, there is a lack of thorough research into the microclimate characteristics of Hakka Tulou. In this study, we investigated the microclimate characteristics in the Hezhou Hakka Tulou. The indoor thermal sensation of the enclosure in warm circumstances was approximately equal to that of cool circumstances. However, the indoor thermal environment of Hakka Tulou could be improved by outer guard structures. In summer, the corridor structure allows for cooling down of the indoor air temperature, while the patio structure has the advantage of dehumidification. However, in winter, the building envelope has the advantages of thermal insulation and moisture-proofing. The location of higher wind speed in summer was mainly orientated from the center of the Hakka Tulou; however, this center appeared in the patio space. Such special environmental factors may be useful for the purpose of warmth in winter and coolness in summer. Furthermore, the patios of the Hakka Tulou effectively improved the lighting coefficient and illumination in the courtyard. However, the daylighting capacities of the inner rooms were considerably lower than those in the outer rooms.

著名住宅的小气候特征:以河州客家土楼为例

客家土楼是当地著名的土方建筑,被联合国教科文组织列为世界遗产。据我们所知,缺乏对客家土楼微气候特征的透彻研究。在这项研究中,我们调查了贺州客家土楼的小气候特征。在温暖的环境中,外壳的室内热感大约与凉爽的情况下相同。然而,客家土楼的室内热环境可以通过外部防护结构来改善。在夏季,走廊结构可降低室内空气温度,而露台结构具有除湿的优势。但是,在冬天,建筑围护结构具有隔热和防潮的优点。夏季较高风速的位置主要是从客家土楼的中心定位的。但是,这个中心出现在露台空间中。这些特殊的环境因素对于冬季保暖和夏季凉爽的目的可能是有用的。此外,客家土楼的天井有效地提高了院子的采光系数和照明度。但是,内部房间的采光量大大低于外部房间的采光量。
