Webster Outlying Field at Naval Station Patuxent
In 2014, the U.S. Navy awarded CEG a federal ESPC project for Naval Air Station Patuxent River at the Webster Outlying Field Annex, a secure research facility and active airfield. CEG will upgrade 72 buildings across Webster Outlying Field and will implement five major energy conservation measures.
CEG will install new control systems and Ground-Source Heat Pumps to replace existing oil-fired boilers and air-source chillers in five of the largest buildings at the base. Across the base, CEG will upgrade the interior and exterior lighting, building controls, domestic water fixtures, and building envelopes.
This groundbreaking project is expected to reduce energy consumption in the Webster Outlying Field retrofit buildings by 38% and generate over $875,000 of annual utility and maintenance savings in the first year of performance. These energy savings will help the Navy achieve its goal of reducing total energy consumption and providing improved energy security. The project will also reduce carbon dioxide emissions by over 5 million pounds per year, by largely eliminating use of fuel oil at the base. This is equivalent to the average annual emissions from 536 passenger vehicles or 232 homes.
Many of the buildings included in scope contain secure laboratories and testing spaces, mechanical and repair shops, and industrial facilities. CEG has worked closely with the Navy to develop safety and implementation plans that will ensure safety requirements are met and implementation does not interfere with building occupants or mission requirements. CEG also worked closely with the Navy to develop a custom approach to O&M and R&R for each individual ECM that ensures continued performance of all ECMs while also controlling costs for the project.
Estimated Savings: $29,300,000
- Annual Savings Over $875,000
- Electricity Savings of 2.6 million kWh/year
- Fuel Oil Savings of 83.5 kGal/year
- Water Savings of 2,800 kGal/year
