Experience
The Maryland Transportation Authority (MDTA) operates all of the bridges, tunnels
and toll plazas across the state of Maryland. Since 1971, the MDTA has been
responsible for constructing, managing, operating and improving the State’s toll
facilities, as well as for financing new revenue-producing transportation projects.
The MDTA’s eight toll facilities, two tunnels and four bridges help keep traffic
moving in Maryland.
The MDTA selected Energy Systems Group (ESG), a specialized energy services
and performance contracting company (ESCO), to complete over $8.6 million of
infrastructure upgrades and comprehensive energy conservation measures to 46
buildings at eight locations statewide. These measures and improvements will
result in energy savings of $640,000 annually and a reduction in maintenance
costs of $184,000 annually.
Strategies & Solutions
The energy conservation measures and infrastructure improvements
developed by ESG include advanced-technology LED lighting which will replace
existing sign lights throughout the State, including the Bay Bridge. The facility
improvements include:
• New Boilers
• Expanded HVAC DDC Controls
• Upgraded Lighting and associated controls
• PV System – Solar Heating
• Water Conservation
• Building Envelope Upgrade
Environmental Benefits
This sustainable project will result in 30% reduction in energy usage in
facilities; 69% reduction in energy usage in sign lights and will provide annual
environmental benefits equivalent to the removal of emissions from more than
850 cars or generating enough electricity to power more than 645 homes.
