Building Energy Management Systems
Building Energy Management Systems (BEMS) is an integrated system of software, hardware and services that controls energy use through information and communication technology.
It monitors, automates, and controls building systems such as heating, ventilation, air conditioning, thermostats, and lighting to increase building energy efficiency and improve comfort in a very wide application area.
A BEMS can monitor, control, and use alarm operations regarding energy issues, indoor conditions, power needs on a real time basis data coming from many various sources.

Building Energy Management Systems
The market of BEMS is growing day by day so the need to gather, control, and interpret all collected data.
EMS revenue is expected to grow to $10.8 billion by 2024.

Achieve Energy savings of 15-20% for heating, cooling, ventilation while energy savings for lighting can be as high as 50-60%.
Reduce energy costs and therefore lower operating costs.
Automatic load cut and peak load management incurred decreased energy costs.
Improve the quality of the indoor environment.
Greater building functionality and economy.
