Energy Management System
Product Details
System Brief Introduction
The Energy Management System is built on the latest service-oriented, cloud-computing and mobile architecture. By collecting energy-consumption data from various monitoring points (substation and distribution, lighting, air conditioning, water supply and drainage, gas, key equipment), it performs professional data analysis and processing to produce statistical analysis of energy consumption by category, item, time and area. This gives enterprises full visibility into energy use, intuitively reveals optimization opportunities, and helps them optimize energy use, reduce overall energy consumption and achieve energy-saving and efficiency gains.

Business Background
As energy becomes scarcer and the environment deteriorates, obtaining economical, convenient and environmentally friendly energy has become an urgent issue for human survival and sustainable development. Finding ways to improve energy efficiency has become a shared responsibility of society — from households to enterprises and governments. Water, electricity and gas equipment and classified energy consumption form a major part of industrial facilities and social infrastructure; a sensible layout of energy facilities and control functions can significantly improve facility and energy efficiency and reduce costs. For enterprises, rising energy costs are a real development challenge. Building a safe, stable, reliable, economical and efficient energy management system with high-tech information technology is of great significance for reducing enterprise costs and improving product market competitiveness.
Application Scenarios
The Energy Management System can be widely used in industrial enterprises, commercial buildings, public buildings and other energy-consuming sites, helping owners fully understand energy-use information, identify unreasonable energy use, and receive energy-saving optimization suggestions, ultimately achieving safe, economical and green energy use.
