Reducing energy consumption in commercial buildings is an essential goal for businesses that want to minimise costs and support a sustainable future. The International Energy Agency (IEA) states that buildings are responsible for over a third of global energy consumption and emissions.
From office blocks to retail centres, factories, and warehouses, every commercial space consumes energy, and that energy often comes at a high price. Whether it’s through heating and cooling systems, lighting, or equipment, finding ways to be more energy-efficient can lead to substantial cost savings and environmental benefits.
In this guide, we’ll explore practical ways to reduce energy usage in commercial buildings, covering everything from lighting systems and lifts to energy management strategies that help save on energy bills and make a noticeable impact.
Understanding Your Building’s Energy Consumption
The first step in reducing energy consumption is understanding where it’s going. Conducting an energy audit is a crucial starting point for any energy-saving strategy. This audit helps identify areas where your building is using the most energy, where energy waste is occurring, and what can be done to improve the overall building energy performance.
An energy audit might uncover that older heating and cooling systems are consuming more energy than necessary or that outdated lighting setups are causing unnecessary energy consumption. With this knowledge in hand, you can develop a plan to tackle the biggest energy drains and work towards substantial energy savings.
8 Ways to Reduce Energy Consumption in Commercial Buildings
Lift Systems and Energy Efficiency
For buildings with lifts, like office towers or residential complexes, lift systems can play a major role in power consumption. Modern lifts are designed with energy efficiency in mind, featuring advanced motors, regenerative braking, and smart energy management systems. However, many older lifts still in operation may lack these features, leading to unnecessary energy consumption.
One key solution is lift modernisation and to upgrade lifts to energy-efficient models that use technologies like variable frequency drives (VFDs) to optimise power usage. Additionally, building management systems (BMS) can monitor lift operations, ensuring they are only in use when needed and even providing data on energy usage patterns. This approach not only cuts energy waste but also contributes to the overall building efficiency.
If replacing lifts isn’t feasible, regular maintenance can also help improve their performance. Proper lubrication, alignment, and adjustments to speed controls can make existing lifts more energy efficient, reducing the strain they place on your energy bills.

Lighting: Switching to LEDs
One of the easiest ways to achieve immediate energy savings in a commercial building is to switch from traditional lighting to LED lighting. LED bulbs use a fraction of the electricity required by older incandescent or fluorescent lights, while also having a much longer lifespan.
For large spaces such as warehouses, shopping centres, and office blocks, the savings can be significant. Not only does this reduce energy consumption, but it also lowers maintenance costs due to the longer lifespan of LEDs.
LED lights can save up to 90% less energy than incandescent bulbs and 60% less than fluorescent bulbs.
Pairing LED lighting with motion sensors or daylight harvesting systems can take things a step further. Motion sensors ensure lights are only used when people are present, while daylight harvesting adjusts lighting levels based on the natural light entering the building. Together, these solutions can help eliminate energy waste.
Optimising Heating and Cooling Systems
Heating, ventilation, and air conditioning (HVAC) systems are often one of the largest energy consumers in a commercial building. A poorly optimised system can waste a great deal of energy, leading to inflated energy costs. However, by investing in an efficient system and implementing proper maintenance routines, it’s possible to reduce energy costs while maintaining a comfortable environment for employees and visitors.
First, ensure your HVAC system is regularly serviced. Filters need changing, and the system should be checked for leaks, faulty components, and other issues that could be affecting its performance. An energy-efficient system will operate more smoothly, consuming less power and offering a quick return on investment in the form of reduced energy bills.
You can also consider installing smart thermostats. These devices can be programmed to control temperatures based on occupancy and time of day, ensuring you’re not heating or cooling spaces unnecessarily. By aligning the HVAC system’s output with the actual needs of the building, you can save energy and achieve substantial energy savings without compromising comfort.
Building Management Systems (BMS)
A Building Management System (BMS) can be an invaluable tool for overseeing and optimising the energy consumption of a commercial building. These systems use sensors and automated controls to manage HVAC, lighting, lifts, and other energy-consuming equipment.
The key advantage of a BMS is its ability to monitor real-time data on energy usage and make adjustments automatically. This means that energy consumption can be optimised continuously, reducing waste without the need for manual intervention.
A BMS can also detect when energy consumption patterns change, such as an unexpected increase in heating or lighting use, and help facilities managers act quickly to correct the issue. Over time, this reduces energy costs and ensures that every part of the building is operating as efficiently as possible.

Reducing Energy Waste Through Behavioural Changes
While upgrading systems and equipment is important, addressing energy consumption habits is equally vital. Simple behavioural changes can make a big difference in the energy efficiency of a commercial building. This includes encouraging employees to switch off lights, computers, and other equipment when not in use and promoting the responsible use of heating and cooling systems.
Educational programs or campaigns within the workplace can help reinforce the importance of energy efficiency. By fostering a culture of saving energy, businesses can achieve substantial energy savings with minimal investment.
Energy-Efficient Building Design and Retrofitting
For businesses looking to make a bigger impact, energy-efficient building design is an effective way to reduce energy consumption. If you’re constructing a new commercial building or retrofitting an existing one, there are several design elements that can enhance building energy performance.
This might include using high-quality insulation to prevent heat loss, installing double-glazed windows, or incorporating green roofing systems to regulate temperatures more effectively. These measures reduce the need for excessive heating or cooling, translating into energy savings.
Retrofitting can also include upgrading old appliances and systems to more energy-efficient models. From replacing old boilers with modern, energy-efficient ones to upgrading lift systems, every small change adds up in terms of energy savings.
Renewable Energy Solutions
For businesses serious about long-term energy reduction, incorporating renewable energy solutions can be a game-changer. Solar panels, wind turbines, and even geothermal heating can significantly reduce dependency on traditional energy sources, leading to lower energy bills and promoting a sustainable future.
Though the upfront cost can be high, the long-term savings and environmental benefits are worth considering. Some businesses may also be eligible for government incentives or grants, further reducing the financial burden of switching to renewable energy.
Monitoring and Continuous Improvement
Finally, energy efficiency is an ongoing process. Regularly monitoring your energy consumption and reviewing your energy management strategies is essential for maintaining efficiency over time. Using energy-monitoring software can help track progress, identify areas for further improvement, and ensure you continue to achieve energy efficiency.
