Fine-Grained Access to Smart Building Energy Resources

Smart city ecosystems provide fundamental resource services such as water and electricity through an intelligent management system. Here, the authors focus on energy resources for smart grids and smart buildings, investigating how a smart grid infrastructure accesses the energy resources in a smart building to obtain or control data. The energy service interface (ESI), which plays a communication gateway role at the boundary of a customer building, hasn´t received much study. The authors examine its design principles for enabling fine-grained access, implement and deploy an ESI prototype, and illustrate interactive energy services between the grid infrastructure and smart buildings.
