As summer temperatures rise, so do energy bills—especially for commercial spaces that rely heavily on HVAC systems, lighting, and equipment during peak hours. For building owners and property managers, keeping electrical costs under control without sacrificing comfort or productivity is critical. Here are smart, practical strategies to cut energy usage and save money during the hottest months of the year.
1. Optimize HVAC Efficiency
Air conditioning can account for 40% or more of a commercial building’s summer electrical bill. To reduce that burden:
- Schedule regular maintenance: Dirty filters, clogged coils, or outdated systems work harder and waste energy.
- Upgrade thermostats: Smart thermostats automatically adjust temperatures based on occupancy and peak hours.
- Seal air leaks: Prevent cool air from escaping with proper insulation, weather stripping, and sealed ductwork.
2. Switch to LED Lighting
Replacing fluorescent or incandescent bulbs with LED lighting can reduce energy use by up to 75%. LEDs also produce less heat, which indirectly lowers cooling costs.
- Use motion sensors and timers in bathrooms, breakrooms, and hallways to avoid unnecessary lighting.
- Daylight harvesting systems can automatically adjust interior lighting based on natural sunlight.
3. Implement Energy Management Systems
Modern energy management systems (EMS) give you real-time data on where your building is using power inefficiently. With this insight, you can:
- Identify peak load times
- Reduce demand charges from your utility provider
- Adjust equipment schedules to avoid using everything at once
4. Consider Off-Peak Scheduling
Many commercial electric rate plans charge more during peak hours (often 11 a.m. to 7 p.m.). By shifting heavy energy use to early morning or late evening:
- Run large equipment before or after peak times
- Stagger start-up of HVAC systems on multiple floors
- Encourage staff to shut down unused electronics midday
5. Upgrade Electrical Infrastructure
Older systems often lack the efficiency of modern equipment. An investment in:
- High-efficiency HVAC units
- Variable frequency drives (VFDs) for motors and pumps
- Power factor correction systems
can lead to long-term savings and fewer service disruptions during extreme weather.
6. Schedule an Energy Audit
An energy audit from a licensed commercial electrician can uncover hidden inefficiencies and opportunities for savings. At White Light Electric, we help building owners analyze usage patterns, recommend upgrades, and even assist in applying for utility rebates.
Final Thoughts
Cutting electrical costs in summer doesn’t have to mean sacrificing productivity or comfort. With the right strategies and smart planning, commercial buildings can stay cool—and cost-effective—all season long.
