Offlate buildings account for a large fraction of energy consumption. In an effort to economize scarce fossil fuels on earth, sensor networks are a valuable tool to increase the energy efficiency of buildings without severely reducing quality of life. Within a smart building many sensors and actuators are interconnected to form a control system. Nowadays, the deployment of a building control system is complicated because of different communication standards. This paper presents a web services-based approach to integrate resource constrained sensor and actuator nodes into IP-based networks. A key feature of approach is its capability for automatic service discovery. For this purpose, it implemented an API to access services on sensor nodes following the architectural style of Representational State Transfer (REST).
