建筑经济CONSTRUCTIONECONOMY第44卷第S1期2023年7月Vol.44No.S1Jul.2023摘要：川西上里古镇的韩家大院是典型的木结构四合院民居。通过软件对建筑室内外的热环境、风环境进行数值计算分析，以围护结构、空间布局以及窗墙比等方面为切入点，探讨川西四合院民居的被动式节能优化策略，并证明优化策略具有一定的经济性。结果显示：增强围护结构的热工性能，冬季室内平均温度能提高1.1℃。增加南北向墙的开窗面积并控制窗墙比，能增大室内的平均风速。被动式节能优化策略在6.7a周期后，改造成本能够得到完全回收。关键词：川西；传统四合院；热环境；模拟分析；被动式策略中图分类号：TU822；TU18文献标识码：A文章编号：1002-851X（2023）S1-0391-06DOI：10.14181/j.cnki.1002-851x.2023S1391SimulationStudyonPassiveEnergySavingBenefitsofCourtyardResidentialBuildingsinWesternSichuanLAIQin1，LIUWei1，2，LIXing3，DONGXinyi1（1.SouthwestMinzuUniversity，Chengdu610207，China；2.TsinghuaUniversity，Beijing1000083，China；3.SichuanUniversity，Chengdu610065，China）Abstract：HanfamilycourtyardinShangliAncientTowninwesternSichuanisatypicalwoodenstructurecourtyardhouse.Throughthesoftwareanalyzesthebuilding’sindoorandoutdoorthermalenvironment，windenvironmentnumericalcalculation，withtheenvelopestructure，spacelayout，andwindowwallratioastheentrypoint.Thispaperdiscussesthepassiveenergy-savingoptimizationstrategyofwesternSichuancourtyardresidentialbuildings，andprovesthattheoptimizationstrategyhasaspecificeconomy.Theresultsshowthattheaverageindoortemperatureinwintercanbeincreasedby1.1℃byenhancingthethermalperformanceoftheenclosurestructure.Theaverageindoorwindspeedcanbeincreasedbyincreasingthewindowareaofthenorthandsouthwallsandcontrollingthewindowwallratio.Afterthe6.7acycle，apassiveenergy-savingoptimizationstrategycanfullyrecoverthereconstructioncost.Keywords：westernSichuan；traditionalcourtyard；thermalenvironment；simulationanalysis；passivestrategy被动式建筑节能技术是利用非机械电器设备的介入来减少建筑能耗的节能技术，它可以通过建筑自身围护结构的保温隔热性能、利用自然通风的门窗设计等减少建筑采暖、制冷、通风的能耗。川西四合院民居...
