WiththerapiddevelopmentofChina'sconstructionindustry,buildingenergyconservationhasalwaysbeenoneoftheimportantstudysubjects.Despitegreateffortinthisresearchfield,buildingenergyconsumptioninChinaremainedconspicuouscomparedwiththedevelopedcountries.Inrecentyears,bothnationalandlocalauthoritieshavemadenormsandstandardsforthebuildingenergyefficiency,whichhasplayedacertainroleintheprotectionandsupportintheenergyconservationofexistedandnewbuildings.However,westilllackenergy-savingstandardsforthespecialkindofbuildingssuchashighwayserviceareas.Characteristicbyhighpopulationconcentrationandbigheatingenergyconsumption,theexpresswayserviceareainseasonalfrozenregionsrequiredmoreattentiontoitsenergyconservation.Basedonthestudybackgroundandthereasonsabove,IperformedmypaperworkwiththeprojectofJILINProvincialCommunicationDepartment.,Istudiedthekeytechniquesforbuildingenergyefficiencyofhighwayserviceareainseasonalfrozenregions,exploredtheoptimizationofthebuildingenvelopesystemforenergy-saving,andputforwardtothestrategyoftheapplicationofthe65%energysavingtechnologiesfortheGongzhulinghighwayserviceareainSipingbureau,thebranchofthehighwayadministrationinJilinprovince.
