Solar　concepts　show　potentially　an　improved　cost-performance　(energy)　ratio　when　applied　as　the　integrated　parts　of　building　renovations.　This　paper　reported　a　compact　solar　thermal　facade　(STF)　module　with　the　internally　extruded　flow　channel　suiting　for　solar　renovation　concept　in　buildings.　A　few　of　impact　factors　were　considered　for　the　parametric　study　in　order　to　optimize　the　STF＇s　configuration　for　various　applications　through　the　validated　simulation　model.　The　overall　research　results　are　expected　to　be　useful　for　further　improvement　in　the　thermal　performance　of　solar　renovation　measures.　(C)　2016　The　Authors.　Published　by　Elsevier　Ltd.
