This　paper　proposes　design　strategies　for　renovating　traditional　communities　in　Beijing　based　on　measured　microclimate　and　thermal　comfort　and　preserving　historical　authenticity　to　empower　residents　to　make　autonomous　decisions　about　the　renovation　process.　Based　on　the　collected　data　from　11　hutongs　and　102　courtyards　in　Dongcheng　District,　4　representative　courtyards　and　2　representative　hutongs　are　summarized.　Microclimate　data　were　collected　in　the　representative　months　of　January　and　September　2022.　The　design　guidelines　for　4　courtyards　and　2　hutongs　design　guidelines,　including　20　renovation　modes,　are　proposed　through　on-site　measurement　and　thermal　comfort　analysis.　Due　to　the　difference　in　microclimate,　the　proposed　design　guidelines　can　only　be　applied　to　the　public　space　of　traditional　communities　in　Beijing　but　not　to　the　public　space　in　traditional　villages　in　the　suburbs.　The　application　of　the　results　also　faces　two　challenges:　the　willingness　of　the　public　to　participate　in　the　renovation　work　and　the　demolition　of　illegal　buildings.　This　study　emphasizes　human　comfort　as　a　factor　to　be　considered　in　renovation　projects.　This　study　provides　a　standardized　method　for　public　space　renovation　in　historic　districts　through　microclimate　analysis　and　thermal　comfort　assessment.　©　2023　Elsevier　Ltd
