What is LoRaWAN and How is it Used in Energy Management?

Energy usage

Energy usage

 

As organisations look for smarter, more efficient ways to monitor and control energy usage, new technologies are reshaping the industry. One of the most effective and scalable solutions is LoRaWAN — a wireless communication technology that makes it possible to connect hundreds of devices and sensors across large sites without the need for complex cabling or expensive infrastructure.

But what is LoRaWAN, how does it work, and why is it becoming so important in energy management?

What is LoRaWAN?

LoRaWAN stands for Long Range Wide Area Network. It is a low-power, wide-area networking protocol designed to connect devices over long distances while consuming very little energy. Unlike Wi-Fi or cellular networks, LoRaWAN can transmit data several kilometres, making it ideal for large industrial, commercial, or campus-style environments.

The system is built around three main components:
• End devices (sensors/meters) – Installed on-site to collect data such as electricity, gas, or water usage.
• Gateways – These receive signals from the devices and pass them on to the network server.
• Network server and platform – Manages the data, ensuring it reaches the correct application for monitoring, analysis, and reporting.

How Does LoRaWAN Work in Energy Monitoring?

When used for LoRaWAN energy monitoring, sensors placed throughout a building or site automatically transmit data on energy consumption to a central platform. Because LoRaWAN has such long-range capabilities, a single gateway can cover an entire building or even a multi-building site.

This makes it possible to collect highly accurate, real-time data without installing extensive cabling or relying on costly SIM-based solutions. The information is then analysed in an energy management platform, giving managers visibility of consumption patterns and inefficiencies.

Why Use LoRaWAN in Energy Management?

The adoption of LoRaWAN systems for energy management is growing rapidly because it addresses many of the challenges businesses face in monitoring energy use:

• Wide Coverage – Ideal for large facilities, campuses, and industrial sites.
• Low Power Consumption – Sensors can run for years on a single battery, reducing maintenance costs.
• Scalable – Easily add new devices as monitoring requirements grow.
• Cost-Effective – Minimal cabling and infrastructure needed compared to traditional metering systems.
• Real-Time Insights – Data is collected continuously, helping organisations respond quickly to inefficiencies.

For businesses aiming to improve efficiency, reduce costs, and hit sustainability targets, LoRaWAN energy management provides a flexible and future-ready solution.

Reducing Energy Costs in Large Office Blocks and Multi-Site Businesses

Energy management system

For many businesses, energy is one of the largest controllable overheads — and in large office blocks or across multiple sites, the collective cost can be substantial. From heating and cooling to IT systems and lighting, energy consumption in office environments adds up quickly. With a well-designed energy management system, businesses can identify where their energy is being used, highlight areas of waste, and implement strategies that deliver meaningful savings.

A typical office building consumes energy across a wide range of systems. Heating, ventilation, and air conditioning (HVAC) are often the single largest users, as they are responsible for maintaining a comfortable working environment throughout the day. Lighting is another significant factor, with office spaces, meeting rooms, reception areas, and car parks requiring constant illumination.

IT infrastructure adds further demand, with hundreds of computers, printers, and servers running daily — and many left on standby overnight. Catering facilities such as kitchens and staff break areas, along with shared spaces like lifts and circulation areas, also contribute to the overall energy load. Without accurate monitoring, it is difficult for businesses to pinpoint which of these areas represents the greatest opportunity for savings.

Deployment of Energy Management Systems

By deploying Elcomponent’s advanced energy monitoring systems, businesses gain a clear and granular view of consumption across all their office spaces. This level of insight allows them to track how different departments or buildings use energy, spot anomalies such as equipment running overnight, and benchmark performance across multiple sites.

The data not only reveals inefficiencies but also highlights where investment should be focused to deliver the highest return, helping decision-makers turn energy into a managed cost rather than an uncontrollable overhead.
There are also a number of practical steps that office-based businesses can adopt to reduce bills once they understand their energy profile.

Upgrading to LED lighting with occupancy sensors can deliver immediate savings, while optimising HVAC systems ensures heating and cooling schedules match actual building use. IT policies can be introduced to ensure PCs, printers, and monitors are fully powered down outside working hours, and hybrid working patterns can be taken into account by adjusting energy use to reflect lower occupancy levels. Beyond this, engaging employees in energy-saving behaviours can help embed a culture of efficiency across the organisation.

Integrated Energy Monitoring Across Multisite Operations

For businesses with offices spread across the country, an integrated energy management installation provides central oversight of every site through one system. This makes it possible to view total business energy consumption at a glance, identify underperforming sites, and share best practices between locations. It also provides a platform to coordinate progress towards sustainability and net zero targets on a company-wide scale.

Large office buildings and multi-site businesses have enormous potential to reduce their energy bills. With Elcomponent’s energy management solutions, organisations gain the insight needed to cut waste, optimise performance, and reinvest savings where they matter most.

Reducing Energy Consumption in Schools, Colleges and Universities

Energy Consumption

Energy Consumption

 

Energy is one of the largest overheads for schools, colleges, and university campuses. With multiple buildings, extended operating hours, and high demand from staff and students, costs can rise quickly if consumption isn’t monitored and controlled.

A well-designed energy management system gives education establishments the tools they need to understand exactly where energy is being used — and where it’s being wasted. With this insight, schools and universities can cut costs, reduce their carbon footprint, and reinvest savings back into frontline education.

Where Education Establishments Use the Most Energy

The daily operation of a campus relies on a wide range of energy-intensive systems. High-consumption areas typically include:

• Heating and Hot Water – Essential for classrooms, halls, and accommodation blocks, especially during colder months.
• Lighting – Covering classrooms, corridors, sports halls, libraries, and external spaces.
• IT and Equipment – Hundreds of computers, printers, projectors, and lab equipment running throughout the day.
• Catering Facilities – Kitchens, dining halls, and canteens with ovens, refrigeration, and ventilation.
• Specialist Facilities – Science labs, swimming pools, and sports centres, all of which require substantial energy.
Without detailed monitoring, identifying the biggest opportunities for savings can be challenging.

The Role of Energy Management Systems

By deploying Elcomponent’s advanced energy monitoring systems, schools and universities can collect real-time, granular data on their consumption. This allows them to:

• Pinpoint inefficient heating or lighting schedules.
• Track high-demand areas such as kitchens, IT suites, and labs.
• Compare usage across departments or buildings.
• Highlight anomalies such as equipment left running overnight or during holidays.
• Measure the impact of energy-saving initiatives over time.
This level of visibility turns energy from a fixed overhead into a controllable cost.

Simple Solutions for Education Sector Savings

Alongside monitoring, there are practical steps education providers can adopt to reduce their bills:

• Lighting Upgrades – Replacing outdated bulbs with LED technology and using motion sensors in corridors or toilets.
• Heating Controls – Adjusting thermostats, zoning heating by building, and ensuring boilers are maintained.
• Holiday Shutdowns – Powering down IT suites, lab equipment, and catering facilities when not in use.
• Engagement Programmes – Involving staff and students in energy-saving initiatives to encourage behavioural change.
• Smart Scheduling – Using real-time data to align energy use with building occupancy.

When supported by a comprehensive energy management system, these measures deliver measurable savings.

How Businesses Can Reduce Their Energy Bills with Smarter Management

Business Energy Bills

With energy costs remaining a major pressure for UK organisations, the question of how to reduce business energy bills is more relevant than ever. From adopting simple efficiency measures to deploying advanced monitoring technology, there are a range of ways companies can take control of their consumption and achieve long-term savings.

Options for Reducing Business Energy Bills

Businesses today have several options available to reduce energy costs:

• Behavioural Changes – Encouraging staff to switch off unused equipment, adjust heating/cooling, and optimise working hours.
• Efficient Equipment – Upgrading to LED lighting, energy-rated appliances, and optimised HVAC systems.
• Renewable Integration – Using solar PV or on-site generation to reduce reliance on the grid.
• Time-of-Use Shifting – Running energy-intensive processes during off-peak hours to lower tariffs.

While these actions deliver measurable benefits, they are most powerful when guided by accurate data. That’s where a comprehensive energy management installation makes the difference.

The Role of Energy Management Installation

A properly designed energy management installation combines sub-metering, smart meters, and monitoring platforms to provide businesses with granular, real-time data on how energy is used. This gives decision-makers the insight needed to identify hidden inefficiencies and implement targeted savings strategies.

With Elcomponent’s energy monitoring systems, businesses can:
• Pinpoint high-consumption processes and equipment.
• Track the impact of energy-saving initiatives.
• Accurately allocate costs across departments or sites.

This is not just about cutting bills — it’s about building an evidence-based approach to sustainable energy management.

Business Energy in the UK — The Bigger Picture

According to government data, UK businesses consume over 200 terawatt-hours (TWh) of electricity each year — that’s more than 200 billion kilowatt-hours (kWh). Much of this is essential to daily operations, but a significant portion is wasted through inefficiencies.

If the UK’s business community could collectively reduce consumption by just 10%, it would equate to savings of around 20 billion kWh annually. That’s enough energy to power more than 6 million UK homes for a year — while also cutting millions of tonnes of carbon emissions.

Supporting Net Zero with Energy Monitoring

For the UK to reach its net zero targets by 2050, businesses must take a proactive role in reducing consumption. Deploying robust energy management solutions is one of the most effective ways to achieve this.
By turning data into actionable insight, organisations can:

• Reduce operating costs.
• Lower their carbon footprint.
• Demonstrate measurable progress towards sustainability commitments.
• Contribute to a collective national reduction in business energy usage.

Energy use per m² in the UK: how offices, factories and other workplaces compare

Energy intensity

 

 

Why kWh/m² matters

Energy intensity (kWh per m² per year) lets you compare very different buildings on a like-for-like basis. UK government datasets now report median electricity and gas intensities by building use, so you can benchmark offices against factories, warehouses, shops and hospitality. GOV.UK

This article focuses on reliable sources of data, to help you understand the typical usage and costs related to business sectors and building spaces usage, from factories to retail.

Headline benchmarks

Recent official stats (ND-NEED 2024, covering 2022 metered use in England and Wales) and the government’s BEES survey (2014-15) give a clear picture of typical ranges:

  • Hospitality: median electricity intensity 168 kWh/m²; median gas intensity 296 kWh/m². Among the highest per m² due to long hours and catering loads. GOV.UK
  • Factories: median electricity intensity 28 kWh/m²; median gas intensity 72 kWh/m². Low per m² because sites are large, even though total consumption is high. GOV.UK
  • Warehouses: median gas intensity 55 kWh/m²; among the lowest per m² overall. GOV.UK
  • Offices: BEES shows median non-electrical intensity ~90 kWh/m² and office electrical intensity typically <100 kWh/m² in mixed-fuel offices; all-electric offices showed a median electrical intensity 124 kWh/m²GOV.UK
  • Retail/shops: BEES median electrical intensity ~118 kWh/m² with non-electrical around 50 kWh/m²GOV.UK

Two structural effects to remember:

  1. Smaller buildings use more per m². In 2022 the smallest premises had median electricity intensity ~97 kWh/m²vs ~46 kWh/m² for the largest. GOV.UK
  2. Total demand is concentrated. A small share of sites drives most consumption; for example, 80% of electricity is used by the top 7% of buildings. GOV.UK

Converting kWh/m² into £/m² (illustrative)

To turn intensity into cost per m²:
£/m² = (electricity kWh/m² × electricity p/kWh) + (gas kWh/m² × gas p/kWh).

Using indicative 2024-25 non-domestic price ranges from DESNZ/ONS (electricity roughly 20–30 p/kWh, gas roughly 5–8 p/kWh; actual contracts vary), here are example annual costs: GOV.UKOffice for National Statistics

  • Office, mixed-fuel (say 90 kWh/m² electricity, 90 kWh/m² gas):
    £22.50–£27.00 for electricity + £4.50–£7.20 for gas ≈ £27–£34 per m².
  • Factory (28 kWh/m² electricity, 72 kWh/m² gas):
    £5.60–£8.40 + £3.60–£5.76 ≈ £9–£14 per m².
  • Warehouse (illustrative BEES mix 53 kWh/m² electricity, 41 kWh/m² gas):
    £10.60–£15.90 + £2.05–£3.28 ≈ £13–£19 per m².
  • Hospitality (168 kWh/m² electricity, 296 kWh/m² gas):
    £33.60–£50.40 + £14.80–£23.68 ≈ £49–£74 per m².

These are benchmarks not quotes; procurement timing, load profile, standing charges and Climate Change Levy all move the final bill.

The collective bill for UK businesses

In 2022, non-domestic buildings used about 122 TWh of electricity and 156 TWh of gas in England and Wales. At the broad price ranges above, that implies an economy-wide annual energy spend on buildings on the order of £32–£49bn. (Electricity total inferred from ND-NEED’s cumulative table showing 122 TWh; gas total explicitly ~156 TWh.) GOV.UK+1

What this means for action

  • Target the big hitters in each building: offices focus on HVAC, ICT and lighting; factories on process heat and compressed air; warehouses on heating and lighting; hospitality on kitchens, hot water and long hours. BEES end-use splits back this up. GOV.UK
  • Expect quick wins from controls and scheduling. Government surveys consistently find strong savings potential from better controls, lighting upgrades and metering. GOV.UK
  • Measure by meter, manage by m². Track kWh/m² by site and normalise for hours and occupancy so you can compare buildings fairly and prioritise the worst performers. ND-NEED shows intensity has been falling over time, so continuous benchmarking matters. GOV.UK
