For businesses relying on air conditioning to keep people, products or machinery cool, rising summer temperatures can put extra pressure on energy usage and bills.
In this blog, and as part of Groundwork’s wider Beat the Heat summer campaign, we’re highlighting smart energy efficiency measures and behaviour changes that can help businesses cut costs, reduce their environmental impact, and stay productive throughout the summer.
1. Understand Your Energy Use
The first step towards improving energy efficiency is to understand existing usage. Our team are qualified to undertake energy audits to identify inefficiencies in your building or systems. In addition, depending on your type of business, it may be worth installing smart meters or sub-meters for high-use areas and monitoring your energy usage during peak hours to find cost-saving opportunities.
By understanding your energy profile, you can prioritize improvements that will have the biggest impact.
2. Optimize HVAC Systems
Cooling systems account for up to 60% of energy use in many commercial buildings during the summer. Keeping them in peak condition is critical. Here are some things to consider:
- Maintain HVAC units: Clean filters and coils, check refrigerant levels, and inspect ductwork. Remember, if your AC unit has an installed cooling capacity of 12 kW or more, you are required to have a TM44 inspection every 5 years. Contact us for more information on this service.
- Use smart thermostats to schedule cooling based on occupancy and working hours.
- Adjust thermostat settings: Just 1–2 degrees warmer (e.g., 75–78°F or 24–26°C) can result in significant savings.
- Use ceiling fans to circulate cool air more efficiently, reducing the need for AC.
3. Upgrade Lighting and Office Equipment
Older lighting systems and constantly running equipment can increase internal heat and your energy bills. Consider:
- Switching to LED lighting, which generates less heat and uses less power.
- Installing motion sensors and daylight sensors to turn off lights when they’re not needed.
- Encouraging staff to power down unused devices and equipment after hours.
- Investing in Energy Star-rated appliances for kitchen areas, printers, and monitors.
These steps not only reduce cooling loads but also lower electricity consumption overall.
4. Improve Windows & Doors
Small improvements to your building’s structure can pay off quickly.
- Seal windows and doors with weather stripping or caulk to prevent air leaks.
- Install reflective window film or interior solar shades to block radiant heat.
- Consider a cool roof coating or lighter-coloured roofing to reflect sunlight.
- Add exterior shading such as awnings, pergolas, or landscaping for passive cooling.
These physical changes can dramatically lower the amount of heat your building absorbs -reducing the load on your AC.
5. Engage Employees in Energy Efficiency
Efficiency, whether for staying cool or warm, is a team effort. Getting employees involved creates a culture of sustainability and shared responsibility.
- Create visible reminders of your expected behaviours near light switches, thermostats, or communal equipment.
- Offer incentives or competitions for departments that reduce energy the most.
- Share real-time energy use dashboards to keep progress visible and motivating.
If you’re struggling to engage your employees in this initiative, dedicated environmental training such as Carbon Literacy may be required to change hearts and minds.
Conclusion
Summer brings challenges but also opportunities. With a proactive approach, your business can reduce energy use, lower costs, and contribute to a more sustainable future.
