Step-by-Step Guide

1. Conduct a Comprehensive Energy Audit

The foundation of any successful energy reduction strategy is understanding where energy is being used—and wasted. Begin by scheduling a professional energy audit. Many Pennsylvania utilities, including PECO, Duquesne Light, and Pennsylvania Power & Light (PPL), offer free or subsidized audits for commercial customers. These audits use specialized tools like blower doors, thermal imaging cameras, and power meters to detect air leaks, inefficient lighting, aging HVAC systems, and phantom loads.

If a professional audit isn’t immediately feasible, perform a preliminary self-assessment. Walk through your office during peak hours and note:

• Which lights remain on in unoccupied rooms
• Whether thermostats are set higher or lower than necessary
• If computers and peripherals are left running overnight
• Whether windows are sealed properly and if drafts are noticeable
• How often HVAC filters are changed

Document your findings and compare them against your utility bills over the past 12 months. Look for spikes in usage during extreme weather and correlate them with operational patterns. This baseline data will help you prioritize improvements and measure future progress.

2. Optimize Heating, Ventilation, and Air Conditioning (HVAC)

HVAC systems account for nearly 40% of energy use in commercial buildings in Pennsylvania. In winter, inefficient heating can cause energy bills to skyrocket; in summer, poor cooling leads to overworked compressors and higher demand charges.

Start by upgrading to a programmable or smart thermostat. Models like the Ecobee or Nest for Business allow you to set different temperatures for occupied and unoccupied hours, adjust remotely via mobile app, and receive alerts for maintenance issues. Set your thermostat to 68°F (20°C) in winter and 78°F (26°C) in summer—these are the recommended benchmarks for energy efficiency without sacrificing comfort.

Ensure your HVAC system is properly sized. Oversized units cycle on and off too frequently, wasting energy. Undersized units run continuously, straining components. Consult an HVAC professional to evaluate your building’s load requirements based on square footage, insulation levels, window orientation, and occupancy patterns.

Replace air filters every 1–3 months, depending on usage and air quality. Dirty filters restrict airflow and force the system to work harder. Seal ductwork with mastic sealant (not duct tape) to prevent up to 30% of conditioned air from escaping through leaks. Insulate ducts in unconditioned spaces like attics or basements with R-6 or higher insulation.

3. Upgrade Lighting Systems

Lighting contributes 15–25% of a typical office’s energy consumption. Replacing outdated fluorescent tubes and incandescent bulbs with LED fixtures is one of the fastest ROI energy upgrades available.

LED bulbs use up to 75% less energy and last 25 times longer than incandescent bulbs. In Pennsylvania, many utility companies offer rebates of $1–$5 per LED fixture installed. For example, PECO’s Commercial Lighting Program provides up to $20,000 in incentives for qualifying upgrades. Combine LED retrofits with occupancy sensors and daylight harvesting systems.

Occupancy sensors automatically turn lights off in rooms that haven’t been used for a set period—ideal for conference rooms, restrooms, and storage areas. Daylight harvesting uses photosensors to dim or turn off electric lights when natural sunlight is sufficient. Install these systems near windows and in open-plan workspaces. Pair with light-colored walls and reflective surfaces to maximize natural illumination.

Turn off all non-essential lighting after hours. Implement a “lights out” policy and designate an energy steward in each department to ensure compliance. Use signage to remind staff to switch off lights when leaving a room.

4. Manage Plug Load and Phantom Energy Drain

Phantom loads—energy consumed by devices in standby mode—are often overlooked but can account for up to 10% of an office’s total electricity use. Computers, printers, coffee makers, phone chargers, and monitors left plugged in 24/7 continue drawing power even when “off.”

Combat this by deploying smart power strips. These strips cut power to peripherals when the main device (like a desktop computer) is shut down. For example, when a printer is turned off, the power strip automatically disconnects the scanner, external hard drive, and paper tray. Replace older power strips with ENERGY STAR® certified models.

Establish a policy for shutting down all non-essential electronics at the end of the workday. Encourage employees to unplug personal devices like phone chargers and desk lamps. Provide labeled outlet strips near workstations for easy management.

For shared equipment like copiers and fax machines, enable sleep mode and set timers to power down after 15–30 minutes of inactivity. Consider replacing older models with newer, Energy Star-certified versions that consume 30–50% less energy in standby mode.

5. Improve Building Envelope and Insulation

A poorly insulated building allows conditioned air to escape and unconditioned air to infiltrate—forcing HVAC systems to work harder. Pennsylvania’s cold winters make this especially problematic.

Start by sealing air leaks around windows, doors, electrical outlets, and plumbing penetrations. Use weatherstripping for doors and windows, and caulk gaps in baseboards and trim. For older buildings, consider installing storm windows or low-emissivity (Low-E) window film to reduce heat loss in winter and solar gain in summer.

Check attic, wall, and floor insulation levels. The U.S. Department of Energy recommends R-38 to R-60 for attics in Pennsylvania. If your insulation is below R-30, consider adding blown-in cellulose or fiberglass. For walls, retrofitting may require professional installation, but it can yield long-term savings of 10–20% on heating and cooling costs.

Install insulated curtains or thermal window coverings in offices with large windows. These can reduce heat loss by up to 25% during winter nights. In summer, use reflective blinds or shades to block solar heat gain.

6. Optimize Equipment and Appliances

Office equipment—from refrigerators and microwaves to water coolers and vending machines—can be significant energy drains. Replace outdated appliances with ENERGY STAR-certified models. For example, an ENERGY STAR refrigerator uses about 15% less energy than a non-certified model.

Place refrigerators and freezers away from heat sources like ovens, direct sunlight, or HVAC vents. Ensure they have adequate ventilation space behind them to prevent overheating. Clean condenser coils every 3–6 months to maintain efficiency.

Consider replacing traditional water coolers with bottleless filtration systems that connect directly to the water line. These eliminate the need for plastic bottles and reduce energy use associated with cooling large volumes of water in inefficient units.

For kitchenettes, use energy-efficient microwaves and induction cooktops instead of electric stoves or toaster ovens. Induction cooktops heat food faster and use 20–50% less energy than traditional coil burners.

7. Implement Remote Work and Flexible Scheduling

One of the most effective—but often underutilized—strategies for reducing office energy use is reducing the number of people physically present. Encourage hybrid work models where employees work remotely 2–3 days per week. Fewer occupants mean less demand for lighting, HVAC, and plug loads.

When implementing remote work, ensure your IT infrastructure supports secure, efficient connectivity. Use cloud-based collaboration tools like Microsoft Teams or Google Workspace to minimize the need for large conference rooms and high-power projectors.

For offices that remain partially occupied, implement staggered schedules. If only 60% of staff are in the office on any given day, condition only the occupied zones. Use zoning controls in HVAC systems to heat or cool specific floors or wings based on real-time occupancy.

8. Monitor and Track Energy Use in Real Time

What gets measured gets managed. Install a commercial-grade energy monitoring system to track electricity, gas, and water usage in real time. Systems like Siemens Navigator, Schneider Electric’s EcoStruxure, or even simpler plug-in monitors like Sense or Emporia can provide granular data on consumption patterns.

Set up dashboards accessible to facility managers and department heads. Identify anomalies—such as unusually high usage on weekends or after hours—and investigate the cause. Use this data to fine-tune schedules, adjust thermostat settings, and justify capital investments.

Many Pennsylvania utilities offer free or discounted energy data services. For example, PPL’s Business Energy Dashboard allows customers to view hourly usage, compare performance to similar buildings, and receive alerts for high consumption events.

9. Engage Employees in Energy Conservation

Technology alone won’t reduce energy use—behavioral change is essential. Launch an internal “Green Office” campaign with clear goals, recognition, and incentives.

Train staff on energy-saving practices during onboarding and quarterly refreshers. Create posters, email newsletters, and digital signage highlighting tips like “Turn it off when you leave,” “Use natural light,” and “Unplug your charger.”

Introduce friendly competitions between departments. Offer small rewards—for example, a catered lunch or extra PTO—for the team that reduces its energy use the most over a quarter. Track progress on a public leaderboard.

Appoint “Energy Champions” in each department. These volunteers serve as peer advocates, remind colleagues to conserve energy, and provide feedback on what’s working—and what’s not.

10. Leverage Pennsylvania-Specific Incentives and Programs

Pennsylvania offers a robust array of financial incentives to help businesses reduce energy use. Take full advantage of these programs to offset upfront costs.

• Pennsylvania Department of Community and Economic Development (DCED): Offers grants and low-interest loans through the Clean Energy Fund for energy efficiency and renewable energy projects.

Work with your utility provider early in the planning process—they can help you navigate requirements and maximize funding.

Best Practices

1. Prioritize High-Impact, Low-Cost Measures First

Not all energy-saving initiatives require large capital investments. Start with low-hanging fruit: adjusting thermostats, turning off lights, sealing leaks, and enabling sleep modes. These actions can yield 10–20% savings immediately with minimal cost.

2. Adopt a Lifecycle Approach to Equipment Purchasing

When replacing equipment, don’t just consider upfront cost. Evaluate total cost of ownership (TCO), including energy use, maintenance, and lifespan. An ENERGY STAR-certified printer may cost $200 more than a standard model, but if it saves $50/year in electricity and lasts 5 years longer, the long-term savings are substantial.

3. Schedule Regular Maintenance

Preventive maintenance is critical. Clean HVAC coils, replace filters, lubricate motors, and calibrate sensors quarterly. Neglecting maintenance can increase energy use by 15–30%. Create a digital maintenance calendar and assign responsibilities.

4. Use Natural Ventilation Strategically

In spring and fall, when temperatures are mild, open windows and use fans to cool offices naturally. This reduces reliance on air conditioning. Install window sensors that automatically shut off HVAC systems when windows are opened to prevent energy waste.

5. Design for Flexibility

Use modular furniture and movable partitions to reconfigure spaces based on occupancy. This allows you to condition only the areas in use. Avoid fixed layouts that force you to heat or cool unused zones.

6. Integrate Renewable Energy

Once you’ve minimized consumption, consider generating your own clean energy. Pennsylvania’s net metering laws allow businesses to install solar panels and receive credit for excess electricity sent back to the grid. Many commercial properties have unused roof space ideal for solar arrays. Pair solar with battery storage to maintain power during outages and reduce demand charges.

7. Benchmark Against Peers

Use the EPA’s ENERGY STAR Portfolio Manager to benchmark your building’s energy use against similar office buildings in Pennsylvania. The tool assigns a 1–100 score—75 or higher qualifies for ENERGY STAR certification. Certification enhances your brand and can increase property value.

8. Document and Communicate Results

Share energy savings milestones with employees and stakeholders. For example: “Our office reduced energy use by 22% in 2023—equivalent to taking 12 cars off the road.” Transparency builds pride and reinforces sustainable behaviors.

9. Plan for Seasonal Adjustments

Adjust your energy strategy seasonally. In winter, focus on sealing drafts and optimizing heating. In summer, prioritize shading, ventilation, and cooling efficiency. Update your checklist quarterly to reflect changing conditions.

10. Stay Informed on Policy Changes

Pennsylvania’s energy regulations are evolving. The state’s 2023 Clean Energy Plan includes new requirements for public buildings and incentives for private-sector decarbonization. Subscribe to updates from the Pennsylvania Public Utility Commission (PUC) and the Department of Environmental Protection (DEP) to remain compliant and leverage new opportunities.
