This paper reports the final results of a research project, which aims to achieve better control modeling in building performance simulation by integrating distributed computer programs. The paper focus on developing Web-services based SOAP/XML to run-time couple control and building performance simulation. Data exchange via Webservices allows system components to be loosely-coupled, rather than combined into an integrated building control systems. The paper also details an example apllication using this technology to configure a distributed simulation through an open protocol, like BACnet or LonWorks and so on. Particularity, this paper concerns the relevance and reliability of integrating Web-services with run-time coupling of control and building performance simulation environments over TCP/IP protocol suite. In addition, this approach provides a reusable patterns either for other similar projects or for real automated building applications
