Monitoring and control of energy consumption in buildings using WoT: A novel approach for smart retrofit

Interoperability issues on networks of heterogeneous devices create a relevant and complex challenge. The Word Wide Web Consortium (W3C) develops series specifications, called the Things (WoT), to address this WoT is focused integrating smart things into application layer system using technologies. Thus, expected have great impact retrofit buildings once data from existing future planned systems are able be gathered analysed seamlessly. In paper, we (i) analyse W3C core Building Energy Management System (BEMS) enable universal integration both private public systems; (ii) propose novel architecture for BEMS based specifications; (iii) present real-world architecture. covered in paper allows gathering sensors with standard commands, enabling analysis simple collecting process. By applying these building can benefited from: ability merge scale different devices; easiness access data; reduction development maintenance costs; (iv) offering interfaces BEMS.
