Building　energy　efficiency　(BEE)　is　regarded　as　the　key　sector　in　the　world　for　addressing　climate　change　and　energy　problems,　since　buildings　consume　around　one-third　of　global　energy　and　produce　a　substantial　amount　of　greenhouse　gas　emissions.　It　is　important　to　utilise　BEE　standards　(BEESs)　to　ensure　that　cost-effective　energy　efficiency　opportunities　are　incorporated　into　new　and　existing　buildings.　A　key　question　is　how　the　actual　performance　of　BEESs　can　be　measured　so　that　they　are　developed　in　a　more　sustainable　way.　An　effective　method　that　can　evaluate　BEESs　from　both　quantitative　and　qualitative　perspectives　is　provided,　and　it　fulfils　a　dual　step:　(a)　determining　a　BEES　evaluation　indicator　system,　including　technological,　economical　and　social　indicators,　by　identification,　correction　and　selection;　and　(b)　establishing　the　BEES　evaluation　model:　a　fuzzy　synthetic　evaluation　model　based　on　the　information　entropy　theory　with　the　analytic　hierarchy　process.　The　developed　BEES　evaluation　model　and　the　case　study　of　China＇s　＇Design　standard　for　energy　efficiency　of　public　buildings＇　could　provide　a　comprehensive　framework　to　understand　the　energy　efficiency　performance　of　BEESs　in　China.　The　results　will　help　improve　the　management　of　BEESs　and　ensure　more　sustainable　building　practice.
