This　paper　aims　to　estimate　energy　use　and　CO2　emission　of　university　dormitories　in　sub-　Tropical　China,　as　part　of　a　sustainability　assessment　of　the　university　campuses　in　China.　This　study　is　conducted　by　use　of　a　simplified　economic　input-output　life　cycle　assessment　(EIO-LCA).　The　front　ground　date　are　tenders　information　of　university　dormitories　built　in　the　Fuzhou　university　town　during　2007-　2011　and　energy　bills　of　those　building　over　past　5　years.　The　background　data　stem　from　Chinese　environment　Input-output　table　2007.　The　results　indicate　that　1)　the　use　stage　is　the　dominate　part　of　the　life　cycle　energy　use　and　CO2　emission　of　university　dormitories.　2)　The　consumption　of　electricity　constitutes　the　main　elements　causing　the　life　cycle　CO2　emission　of　university　dormitories.
