Abstract

Veranda serves as a shading and heat protection area for homes in hot and humid regions, connecting indoor and outdoor spaces. However, there is limited literature on precise veranda design for climate regulation. This research focuses on the impact of veranda scale and form on thermal protection, aiming to establish design guidelines for a better indoor and veranda thermal environment. Local residential buildings on Hainan Island are analyzed to study veranda types and layouts. Simulation models, based on local meteorological data and Autodesk CFD software, are used to compare and evaluate different veranda scales and forms. Increasing the overhang from 1.5 m to 3.0 m can improve the thermal comfort of the veranda on first floor by 9.3 %. The number of verandas increased from one side to four sides, reducing the APMV values of the first and second level verandas by 0.26 and 0.1, respectively. The study proposes effective design guidelines for verandas in residential buildings, beneficial for sustainable development in hot and humid areas.

廊道尺度和形式对热防护性能的影响

阳台作为湿热地区家庭的遮阳和热保护区域，连接室内外空间。然而，关于精确的阳台设计用于气候调节的文献有限。本研究着眼于阳台尺度和形式对热防护的影响，旨在建立更好的室内和阳台热环境的设计准则。以海南岛当地民居为研究对象，研究阳台类型和布局。利用基于当地气象数据和Autodesk CFD软件的模拟模型，对不同阳台尺度和形式进行了比较和评估。将悬垂从1.5 m增加到3.0 m，可使一楼阳台的热舒适性提高9.3%。走廊数量由一侧增加到4侧，使一层和二层走廊的APMV值分别降低0.26和0.1。该研究为住宅建筑的阳台提出了有效的设计准则，有利于湿热地区的可持续发展。
