Building Energy Management System: A Review

With an increasing need for reduction in energy consumption level and continuing growth of energy use by commercial buildings has created a need to develop innovative techniques to reduce and optimize building energy use. Recently Building Energy Management System (BEMS) have gained popularity because of increasing interest in building energy conservation and savings. Building Energy Management System has the ability to control and monitor the building's energy needs. Building Energy Management System not only provides indoor thermal comfort but also creating a safe and healthy environment within residential buildings including institutional, commercial and industrial buildings and able to reduce energy consumption. In order to improve the overall energy efficiency and save electricity expenditure of the Building lead to electricity saving. The Objective of this paper is to review different methods or techniques suggested by the researchers for controlling and monitoring the energy consumption patterns in buildings. Additionally, it highlights various developed software in Building Energy Management System Especially BEMOSS (Building Energy Management Open Source Software) and also discuss benefits of Building Energy Management System.
