In　recent　years,　with　the　rapid　increase　of　office　buildings　and　the　requirements　to　improve　the　office　environment,　office　building　energy　consumption　has　increased　significantly.　That　has　brought　great　pressure　to　the　user,　environment　and　city　power　supply　and　demand.　The　electric　energy　consumption　of　office　building　conservation　is　the　most　important　way　to　reduce　the　energy　consumption.　Simulation　is　a　major　method　to　understand　about　office　building　power　consumption.　At　present　domestic　and　foreign　computer　software　simulation　technology　cannot　work　without　a　lot　of　professional　parameters.　And　the　obtained　results　is　so　professional　that　cannot　give　the　management　decision　auxiliary.　This　paper　presents　a　holistic　statistical　distribution　instead　of　complex　thermodynamic　iterative　computation　model,　and　the　analysis　method.　Using　the　mode　＇facing　to　the　whole＇　for　analysis　of　power　energy　consumption　of　office　buildings,　without　more　intricate　parameters,　and　can　be　iterative　adjusted　according　to　the　difference　between　measured　data　and　the　prediction.　©　2016　SERSC.
