Analyzed　and　calculated　the　energy　savings　of　heat　reflective　coatings　applied　on　multi-storied　residential　buildings　and　high-risen　commercial　buildings　in　Beijing.　Some　advices　about　the　application　of　heat　reflective　coatings　in　northern　cold　region　are　given.　Energy　saving　effect　was　evaluated　with　the　building　energy　simulation　in　winter　and　summer　while　the　heat　reflective　coating　is　applied　on　the　surface　of　residential　buildings　and　commercial　buildings.　Calculating　results　showed　that　the　energy　saving　is　the　most　optimal　to　the　multi-storied　buildings　when　the　cool　roof　coatings　is　coated　on　the　roofs　and　the　glass　heat　reflective　coating　is　applied　on　east　and　west　windows.　With　the　high-risen　commercial　building,　the　energy　saving　is　noticeable　when　the　glass　curtain　wall　is　coated　with　glass　heat　reflective　coatings.　The　energy　saving　rate　can　reach　a　maximum　of　13%.　©　(2014)　Trans　Tech　Publications,　Switzerland.
