Why do I need an Energy Management System?

Get on top of rising energy costs and the best place to start is with an Energy Management System (EMS).


As technology continues to evolve at a rapid pace, there are a vast array of new technologies on the market. As a result, identifying the most efficient ways to run a commercial building can become somewhat challenging with so much choice…

Many buildings have a BMS in place which is great. However, what many building owners and managers fail to recognise is that the primary purpose of a BMS is the real control of the building’s plant. The systems are not capable of dealing with historic data or reporting and analysing data.

Therefore, a BMS is just the start of the journey in achieving energy efficiency. In order to make meaningful changes to a commercial building, which are sustainable over the long term, simply acquiring the data through the BMS is not enough. The data must be processed and interpreted to facilitate a change in behaviour and in turn energy savings.

An example of this would be to think of the BMS as the steering wheel which allows you to determine the direction of your car but you still need to make regular checks on the dashboard to ensure that everything is working correctly. Therefore, the EMS is the car dashboard which allows you to see all of the controls and accurately direct your car based on the information which you are given.

An EMS provides detailed analysis of this information in your commercial building. It is then presented in a clear and understandable format for the building owner or manager to determine and prioritise areas for future improvement.

By accessing this data, an effective control strategy can be tested and implemented to better understand energy consumption which is pivotal in maximising potential savings.

The key objective of an EMS is therefore to collect data from the building using an energy monitoring solution in order for the building owner or manager to understand when, and how a building uses energy and develop a detailed plan of action to reduce energy.

For building owners and managers who are unsure of which direction to take to sustainably reduce their energy costs, an EMS is the ideal solution because a visible and effective energy management strategy can only be introduced from gathering, analysing and using the information collected from your building.

So, instead of implementing one-off energy initiatives or upgrades, companies need to focus on sustaining and improving energy use over time and this requires continuous monitoring, analysis and reporting of building performance. By having access to such information within an EMS, it allows you to make informed decisions and decide on the next course of action.

Perhaps it’s time you took the next step into achieving energy efficiency and reduced costs in your commercial building by implementing an EMS. Find out more with our CPD guide to the role of EMS or email us to discuss your requirements.
