摘　　要：广东地区新建农宅有向多层发展和天井消失的趋势,室内热环境因此而变化。为了解广东地区新建农宅室内热环境现状,选取有天井现代农宅、无天井现代农宅和传统农宅各一栋进行现场实测,在对比分析的基础上发现现代农宅室内热环境存在优化的空间。针对广东地区现代农宅存在的问题,借助计算机辅助分析的手法提出适宜的优化措施,屋面遮阳、增大天窗高度及天窗开口置于下风向是改善有天井多层农宅夏季室内热环境的有效措施,无天井现代农宅通过局部架空和窗口遮阳改善室内热环境效果显著。New-built rural residential buildings in Guangdong province have the tendency of multilayer and courtyard disappearance,resulting in the change of the indoor thermal environment.Three typical buildings are selected to measure the parameters of indoor thermal environment in order to understand the status quo of indoor thermal environment in new-built rural residential buildings in Guangdong.It＇s found that there are several defects count against indoor thermal environment on the basis of comparative analysis.Thus,optimizations were made for design strategies such as shading,insulation and natural ventilation in low-rise buildings with/without patios.There are effective measures to improve the indoor thermal environment in summer of low-rise buildings with patios like the shading roof,increasing height of skylight and skylight placed under the wind direction.Numerical analysis was conducted to quantify the energy and comfort performance of these design strategies.Stilt floor was found to be a good way to build semi-open spaces in low-rise buildings without patios.
