Based　on　a　building　energy-consumption　model,　the　building　energy　consumption　from　2002　to　2011　in　China　was　figured　out.　Analysis　on　building　energy　consumption　trends　showed　that　the　building　energy　consumption　would　increase　inevitably　and　drastically.　Meanwhile,　the　analysis　on　green　building　presented　its　well　energy-efficient　performance.　The　results　indicate　that　green　building＇s　development　is　an　urgent　task　in　China.　©　(2014)　Trans　Tech　Publications,　Switzerland.
