What is an energy management system (EMS)?

EMS defined

An energy management system is an integrated suite of tools, technologies and processes designed to monitor, control and optimise energy use in buildings.

By collating energy usage data, automating key processes, analysing usage patterns and providing actionable insights, an EMS helps energy and facilities management teams maximise operational efficiency while minimising energy waste.

Key types of energy management systems

Energy management systems all support the same overarching objectives, but they can take on various forms to meet the specific needs of different industries:

• Utility EMS (UEMS): Tailored for large-scale energy operations, such as utility providers or grids.
• Building EMS (BEMS): Designed for commercial, residential and institutional buildings to optimise energy use and control HVAC, lighting and more.
• Home EMS (HEMS): Focused on residential energy consumption, enabling homeowners to monitor and control their own energy use.
• Industrial EMS (IEMS): Specialised for industrial settings, including warehouses and manufacturing plants to manage complex energy needs effectively.

 

Key benefits of implementing an EMS for your business

Implementing an EMS can be a lengthy and complex process. However, a well-managed EMS can drive ROI across a wide range of business areas:

Cost reduction and financial savings

Energy management software systems allow businesses to track and monitor their energy consumption at a granular level, identifying suboptimal usage trends and inefficiencies that drive up costs. By optimising operations such as heating, cooling and lighting companies can significantly reduce their energy expenses. For example, studies show that energy-efficient upgrades like LED lighting can cut electricity costs by up to 25%, while awareness campaigns to drive behavioural change within buildings can reduce usage by as much as 10%.

Enhancing sustainability and reducing carbon footprint

Improving energy efficiency through an EMS directly reduces greenhouse gas emissions, supporting organisations in achieving their environmental, social and governance (ESG) objectives and Net Zero goals. In doing so, businesses can not only reduce their environmental impact for the good of the planet but can also profit in the form of improved brand reputation. Sustainability and Net Zero have become key real estate sustainability trends in recent years and are only set to become more important as they become key priorities for customers and investors, giving brands that can demonstrate a robust approach a significant competitive advantage.

Real-time monitoring and control

A key benefit of an EMS is that it offers real-time monitoring capabilities, enabling organisations to analyse energy consumption patterns, detect inefficiencies and make data-driven adjustments faster than they could otherwise. This not only helps to improve efficiency by identifying signs of wastage sooner but can also help drive other savings. For instance, temperature sensors monitoring the performance of HVAC equipment can provide an early indication of potential problems, enabling proactive scheduling of maintenance work and preventing unnecessary wear or outages.

How do energy management systems work?

The technical mechanics of energy management systems (EMS)
Energy management systems (EMS) are powered by a suite of modern technologies that work in tandem to monitor, analyse and optimise energy consumption. These systems combine hardware and software to provide actionable insights that enhance efficiency and reduce costs.

Sensors and meters: The foundation of data collection

Sensors and meters are core components of any EMS. These tools provide precise data on energy usage at a site, building, room and even asset level, allowing detailed analysis to identify inefficiencies and target areas for improvement. Advanced sensors also measure variables like temperature, humidity and equipment performance to offer a holistic view of energy use.

AI and machine learning: Predictive intelligence

Cutting-edge EMS platforms leverage artificial intelligence (AI) and machine learning algorithms to predict energy demand, identify trends and flag inefficiencies. These technologies also forecast energy consumption patterns, enabling smarter decision-making.

Smart controls: Automation for efficiency

Smart controls play a pivotal role in optimising energy use. These automated systems adjust lighting, HVAC and other energy-intensive processes in real time, based on data collected by sensors. For instance, lighting can be dimmed during daylight hours, or HVAC systems can be calibrated to maintain ideal conditions with minimal energy waste.

User-friendly interfaces: Actionable insights

EMS platforms provide user-friendly interfaces, including dashboards, reports and alerts, to empower decision-makers. These tools transform raw data into actionable insights, allowing users to track KPIs, evaluate energy-saving initiatives and make informed adjustments. By visualising energy usage and efficiency metrics, businesses can easily monitor their progress toward sustainability goals.

By integrating these technologies, an EMS enables businesses to transition from reactive energy management to proactive optimisation, driving both cost savings and environmental benefits.

Integration with other business systems

EMS platforms often integrate with facilities management software to centrally control HVAC, lighting and automation processes.  For example, MRI Software’s EMS solutions integrate with its facilities management tools, allowing energy data to trigger automated work orders for improved efficiency.

How to implement an energy management system

Successfully implementing an energy management system (EMS) involves a systematic approach to ensure maximum efficiency and value. Here’s a step-by-step guide:

Step-by-step process

1. Assessment

The assessment phase involves understanding whether an EMS is necessary for your business. Start by gathering a top-level overview of current energy usage across your operations and map out any current energy infrastructure, including metering and submetering, renewable generation or particularly energy-intensive equipment or processes. Consider what technology, such as sensors and software features, would be required to meet your needs and any business processes or resources you may need to support these.

2. Select an EMS platform

Choosing the right energy management software (EMS) platform is crucial to achieving your energy management objectives. Compare platforms based on features, scalability and compatibility with your existing systems. Key considerations include user-friendly dashboards, advanced analytics capabilities and real-time monitoring tools.

3. Installation and integration

Install sensors, smart meters and IoT devices to monitor energy usage in real time.  During this phase, ensure that the EMS integrates smoothly with existing infrastructure, including building management systems (BMS) and tenant billing platforms. Proper integration allows the EMS to capture granular data from HVAC systems, lighting and other equipment, laying the groundwork for automation and actionable insights.

4. Monitor and optimise

Once operational, use the EMS to continuously track performance metrics, identify trends and detect inefficiencies. Real-time data enables swift adjustments, whether it’s optimising HVAC settings, reducing peak demand or implementing energy-saving schedules. Review reports from the EMS regularly to verify the achievement of targets and take proactive measures to sustain or enhance performance.
