In　recent　years,　the　intelligence　and　automation　of　building　systems　have　gained　further　development　with　the　development　of　communication　technology.　Based　on　the　characteristics　and　research　progress　of　the　intelligent　building　system,　this　paper　analyzes　some　existing　problems　in　the　existing　intelligent　building　system,　and　then　puts　forward　intelligent　building　universal　control　platform　architecture　based　on　the　multi-agent　system　and　communication　middlew　are,　which　shows　significant　adaptability　and　advantages　in　many　aspects,　including　the　heterogeneous　devices　connection,　collaborative　control,　human-computer　interaction　and　user　self-management.　This　system　can　greatly　improve　the　energy　efficiency　of　building　systems　and　provide　a　new　route　for　the　intelligent　building　research.
