Fuzzy logic as a useful tool for managing resources in multi-energy buildings

The present paper focuses on using fuzzy logic as a useful tool to manage energy resources in buildings and to reduce their energy impact. To that purpose, one requires the design and the implementation of efficient and readily adaptable control schemes. As everyone knows, fuzzy logic allows taking advantage of the flexibility offered by linguistic reasoning. With this kind of approaches, both the specific use of a building and the specificities of a proposed energy management strategy can be easily considered when designing or adjusting the proposed control schemes. First, a hybrid PID-fuzzy scheme is used for managing resources in multi-energy buildings, as the combination of two usual control structures based on PID and fuzzy controllers: the "parallel" structure and the "fuzzy supervision" of a PID controller. Next, fuzzy logic is used to define scenarios dealing with building occupancy and to control the ventilation system of a building, with the aim of reducing its energy impact on the grid.
