BEMS Architecture and Service Modules for Realizing Sophisticated Algorithms

Abstract

There is a growing interest to introduce energy-saving algorithms which balance energy efficiency with residents' comfortability into a Building Energy Management System (BEMS). However, the following issues hinder penetration of the energy-saving algorithms into markets: difficulties both in embedding the algorithms into the BEMS, and in turning the algorithms suitably to fit varieties of installed equipment in each building. In this paper, A BEMS on micro-service architecture, and software service modules for the BEMS, were proposed. The micro-services architecture improves flexibility to introduce newly developed energy-saving algorithms into the BEMS and software service modules manipulate whole roles (Modeling, Planning, Doing, and Action) required for tuning the algorithms on-line to fit the algorithms to each building. Each software service module was implemented and integrated as elements of BEMS on micro-service architecture. The BEMS on micro-service architecture was applied to an actual building for evaluation, and its availability was confirmed through the field test.
