Fairfax County is celebrating Energy Efficiency Week from October 1 to 7, encouraging residents, businesses and community organizations to adopt simple, cost-saving practices that reduce energy waste and lower monthly utility bills.

Improving energy efficiency does not require major renovations, according to the county. Practical upgrades such as LED lighting, better insulation, high-efficiency HVAC systems and heat pump technologies can make a big difference.

The county offers a range of programs to help, including Fairfax Energy Compass for homeowners, the Energy Conservation Assistance Program for nonprofits, the Sustain Fairfax Challenge, Weatherization Assistance for qualifying households, and resources for businesses through Green Business Partners.

Fairfax County said it has already reduced electricity use in government operations by 13% since 2018 and expanded its portfolio to 49 LEED-certified buildings. During Energy Efficiency Week, the community is encouraged to explore available tools and take meaningful steps toward a cleaner, more sustainable future.

As colder weather approaches, the county is also urging homeowners to prepare their homes and keep energy costs under control. A quick, do-it-yourself energy audit can reveal simple fixes, such as sealing air leaks around doors, windows and outlets, adding insulation in attics, basements and exterior walls, replacing furnace filters monthly, and using heat wisely by opening shades during the day and closing them at night.

Fairfax Energy Compass offers free guidance to help homeowners identify practical upgrades, compare options, and find available incentives and qualified contractors.
