Energy Management Systems Reduce Energy Costs for Stores

Electricity supply is fundamental in all business and production processes, such as in department stores where they are expected to maintain their lighting, cash registers and other equipment that are critical to store operation. However, in order to make sure your store is energy efficient, it is important to have an energy management system in place to monitor energy usage for equipment, sectors in the store, HVAC units, compressors etc.

Monitoring energy usage in commercial applications is a field that has arisen due to the need for industry to have a knowledge of the  machinery that is being used, and know exactly what the real power consumption is for each process and equipment. An energy management system is better than hiring energy consultants because it is a system that monitors 24/7 and does not have human error. In addition, once a consultant has finished their review of your facility, he leaves and you have a big pile of statistics and recommendations that seem overwhelming. With an energy management system, you choose the reports you want to see, what loads you want to compare, dates, locations, square footage of facility etc. You only get a report on what is critical for that day and information that is useful for the project you are undertaking.

The advantages of using a monitoring systems to control electricity consumption, is to know what equipment is consuming more energy, if any equipment is malfunctioning, as well as automatic control of HVAC, refrigeration, etc.
A technology based company called Energy Controls has years of experience implementing energy management systems in grocery stores. These systems interface with a Building Management System (CPC, Danfoss, Microthermal etc.) and monitors energy usage on up to 25 loads in a facility.

Example of loads that can be monitored in a store are:

Low Temp. Compressors
Med Temp Compressors
Main HVAC (Heating / Cooling)
Deli Department
Bakery Department
Sales Lighting
Décor Lighting
Cooler Lighting / Fans
Sales Floor Lighting
Parking Lot Lights
Main Ovens
Water Consumption
Gas/Oil Consumption

The Energy Management System fro EG Energy Controls has  the capabilities to do demand control and energy monitoring in 1 system. The Energy Surveillance System  is a web-based system capable of monitoring and providing control of up to 2,500 facilities within the corporate network.

How Does the Energy Management System Work?

The system gathers information from the transducers that can measure the energy use in all electrical loads such as: load compressors, lighting, main meter, heating load, air conditioning load etc.
Custom designed email messages can alert the Energy Manager of abnormal energy usage or a pending motor failure.
The system contacts the weather station to collect weather information such as wind speed, temperature, humidity, etc to decide what is “normal” energy usage. In compiling this data, the energy management system can predict the energy use for the next day. This ensures that the user only receives an email about the use of abnormal power.

All this makes it possible for companies small or large to obtain a large decrease in electricity consumption and maintenance costs.
