MAA ESCO Support & Technical Services

Location: Maryland Client: Maryland Aviation Administration

JMT provided technical engineering support associated with review of an ESCO Proposal for BWI and Martin State Airport for implementation of energy reduction measures utilizing an Energy Service Company (ESCO).

The Maryland Aviation Administration (MAA) is the owner and operator of Baltimore/Washington International Thurgood Marshall Airport (BWI) and Martin State Airport.  An Energy Service Company (ESCO) provided MAA with a report and proposal for various energy conservation projects at both airports to improve their energy efficiency and provide cost savings.

JMT was hired to review the reports submitted by the ESCO to confirm that all claimed savings were credible and cost beneficial.  Technical work included Peer Review of calculations, independent cost estimating and systems analysis for functionality, controllability and maintainability.  JMT closely examined all energy savings solutions proposed by the ESCO and provided feedback on the feasibility of achieving the claimed energy savings.  Programs reviewed included a 6.6 megawatt cogeneration system, chiller optimization, controls systems optimization, commissioning efforts, boiler upgrades and improvements, air handling improvements for all zones, lighting controls, application of high efficiency lighting fixtures and a 400 KW Photovoltaic Solar Panel Design.

JMT's findings brought about a considerable change in the ESCO's proposal as we identified that the vast majority of the investment; the cogeneration system, had made too many assumptions that subsequently marred the projected cost savings to a point of a wash.  Although JMT identified a reduced projection in savings for the optimization of chiller and boiler controls, the cost savings were still beneficial as was the case with the lighting controls and the installation of the high efficiency lighting fixtures.
