Functions-focused Building Energy Management Systems: A Review

Building energy management systems (BEMSs) perform essential tasks to enhance energy-use performance. BEMSs play an important role in energy savings because it affects energy management related functions needed by a building. An efficiently designed BEMS would affect building energy efficiency and energy-use. There are several key functions each building might perform one or more than a function to contribute to energy-use depending on the purpose of BEMS embedded in that building. Some BEMSs might perform that a function to come up with a semi-optimal level in energy efficiency and energy-use. This review paper presents several function-purposed BEMSs. Monitoring of energy-use, measurement, analysis, estimation and optimization are some examples of functions BEMS performs. This review paper aims to give readers suggestions on which more suitable and adequate design of BEMS is preferable for a type of buildings than other systems to achieve a better energy management. In this review paper several top-tier researches' publishers e.g., Elsevier, IEEE, and ACM have been used from which papers are collected. This paper has considered papers published since 1982 to cover an extensive trend of research studies used for BEMS.
