Energy Management Systems: What You Need to Know

Energy management systems (EMS) are becoming more and more important in today’s world. These systems help companies control and reduce their energy use. In this article, we will talk about what an EMS is, the benefits of using one, things to consider before investing in one, the typical features of an EMS, and how to choose the right EMS for your company.

What is an EMS?

An Energy Management System (EMS) is a tool that helps companies monitor, control, and save energy in their buildings. It gathers data on energy use and provides important information to the people who manage the company. This data helps them make better decisions about how to save energy and money.

Benefits of using an EMS

  1. Save money: By reducing energy use, companies can save money on their energy bills. This is good for the company and its clients.
  2. Help the environment: Using less energy means creating less pollution. This is good for the planet and helps companies be more environmentally friendly.
  3. Better control: An EMS gives companies more control over their energy use. They can see how much energy is used and where it is used. This helps them make better choices about how to save energy.
  4. Good image: Companies that use an EMS are seen as responsible and forward-thinking. This can help attract new clients and keep existing ones happy.
  5. Improve efficiency: An EMS can help companies identify areas of inefficiency and implement measures to optimize energy usage, leading to better overall performance.

Typical features of an EMS

  1. Data collection: An EMS collects data about energy use from different sources, such as electricity, gas, and water meters. This data is essential for understanding how and where energy is used.
  2. Real-time monitoring: EMS can display energy use in real-time, allowing companies to quickly identify and address any issues or inefficiencies.
  3. Analytics and reporting: EMS can analyze energy use data and generate reports, which help companies understand their energy consumption patterns and find ways to improve.
  4. Alerts and notifications: Some EMS can send alerts or notifications when certain energy use thresholds are reached, helping companies take action to avoid excessive consumption.
  5. Energy-saving recommendations: Many EMS provide recommendations on how to save energy based on the collected data and analytics.
  6. Integration with other systems: A comprehensive EMS can integrate with other building management systems, such as HVAC, lighting, and security, for a holistic approach to energy management.

What to consider before investing in an EMS

  1. Cost: Investing in an EMS can be expensive. Companies need to think about the cost of the system and the installation. However, the savings on energy bills can often make up for these costs over time.
  2. Compatibility: Not all EMS are the same. Companies need to find one that works well with their existing systems and equipment.
  3. Training: To use an EMS properly, the people who manage the company need to learn how to use it. This may take time and effort, but it is important for getting the most out of the system.
  4. Support: It is important to have good support from the company that provides the EMS. This includes help with installation, training, and any problems that may come up.
  5. Scalability: As a company grows, its energy management needs may change. An EMS should be scalable and able to grow with the company.

How to choose the right EMS for your company

  1. Identify your needs: Before selecting an EMS, it is important to determine what your company’s specific needs are. Consider factors such as your building size, the type of equipment you use, and your overall energy goals. This will help you choose an EMS that is well-suited to your requirements.
  2. Research and compare: Once you have a clear understanding of your needs, research different EMS providers and their products. Compare features, pricing, compatibility, and customer reviews to narrow down your options.
  3. Ask for demonstrations: Reach out to EMS providers and request demonstrations or trials of their systems. This will give you a hands-on understanding of how each system works and help you determine which one best fits your needs.
  4. Evaluate customer support: Customer support is a crucial aspect of implementing an EMS. Ensure that the provider you choose offers reliable and responsive support, including assistance with installation, training, and ongoing maintenance.
  5. Consider future needs: When choosing an EMS, think about your company’s future needs. Opt for a system that is scalable and can be easily upgraded or expanded to accommodate growth and evolving energy management goals.


An Energy Management System (EMS) can be a great investment for companies that want to save money and help the environment. By understanding what an EMS is, the benefits of using one, what to consider before investing in one, the typical features of an EMS, and how to choose the right EMS for your company, you can make an informed decision about whether an EMS is right for you. Remember, the key to success with an EMS is proper training and support from the provider. With the right system in place, companies can enjoy lower energy bills, improved efficiency, and a better image in the eyes of their clients.
