Energy Conservation Assistance Program Success Stories

The Energy Conservation Assistance Program started in fiscal year 2016 and has approved $211,932 in grants in support of 34 energy projects either completed or in progress, as of January 2026. In total, these projects will result in nearly $1.1 million in energy efficiency upgrades. 

These projects span various Fairfax County districts, addressing a range of energy needs and priorities. The following charts provide a breakdown of the completed projects by project type, project category and district.

From upgrading lighting systems to installing energy-efficient HVAC systems, several featured projects showcase the diverse ways this program has made a difference across the county. Learn more about the featured projects below:

Featured Projects

  • Project Type: Heat Pump
  • Project Category: Category 2 - Energy Efficiency and Conservation Projects
  • District: Providence

A reimbursement grant of $4,094 was used to replace their air conditioning/gas furnace with a high-efficiency heat pump system. A load calculation indicated a reduction in the size of the system, further contributing to the energy cost savings for this project. A smart thermostat was also installed to enhance the energy savings from pre-set heating and cooling settings based on building occupancy and use. The annual cost savings is expected to be $770.

  • Project Type: LED Lights
  • Project Category: Category 2 - Energy Efficiency and Conservation Projects
  • District: Franconia

A reimbursement grant of $2,704 supported the installation of eight LED parking lot lights and supporting infrastructure in 2024. This project will result in an 87% reduction in energy use and an estimated annual savings of $901 per year. The payback period for this project is only 6 years.

Installation of outdoor LED lighting

  • Project Type: Solar Energy
  • Project Category: Category 3 - Clean/Renewable Energy
  • District: Springfield

A reimbursement grant of $10,000 supported the installation of a 31.99 kW photovoltaic solar system on the roof in 2024. This will provide a 100% offset of their annual energy use. The project is also eligible for the federal Inflation Reduction Act (Direct Pay) tax credit. As a result, the payback period for this project is less than 8 years given an estimated energy cost savings of $4,000 per year and the balance remaining after the grant and tax credit.

  • Project Type: HVAC
  • Project Category: Category 2 - Energy Efficiency and Conservation Projects
  • District: Springfield

A reimbursement grant of $3,750 helped offset the cost of an ASHRAE Level 2 energy audit in 2023. A second reimbursement grant of $10,000 helped fund two (twinned) high-efficiency condensing natural gas furnaces that were installed in 2024 based on a recommendation from the audit.  The new furnaces have an Annual Fuel Utilization Efficiency (AFUE) rating of 95% and are ENERGY STAR® qualified. Replacement of both furnaces with efficient condensing furnaces will provide an annual savings of $429 per year.
