As　multi-agent　meets　characteristics　of　distributed　control　architecture　and　lots　of　nodes　in　intelligent　building,　and　the　construction　is　expected　to　overcome　existing　problems　as　well.　Introduce　agent-based　approach　into　intelligent　building　control　is　of　great　significance.　We　propose　a　model　of　intelligent　building　control　system　based　on　multi-agent　which　owns　a　pure　distributed　architecture.　The　different　functions　and　different　levels　of　agents　in　the　model　are　described.　At　the　same　time,　we　discuss　the　intentional　cooperation　method　used　in　intelligent　building　control　through　an　example　which　was　based　on　multi-agent.　Finally,　we　finish　temperature　and　illumination　control　experiments　on　a　Windows　CE-based　embedded　platform.　©2008　IEEE.
