6. Solar Thermal
• 24 Evacuated solar tube collectors
• Operational Sept 2015
• Located on natatorium roof
• Designed to allow either pool or
DHW to be heated
• Drain-back system prevents overload
of system
• In the first two months the system
saved over 600 Therms
• Projected to save 2,500 Therm
savings per year.

7. Combined Heat and Power (CHP)
• Microturbines

natural gas
• Generate alternative energy credits

8. Geothermal Energy
• Heating and cooling of new LEED
Platinum building
• Provides 120 ton of heating and
cooling
• Building uses natural gas for
domestic hot water and radiant floor
only
• 48-well, vertical, closed loop system
• Uses chilled beam technology

9. Hydrokinetic Energy
• Research program to test
hydrokinetic designs
• Uses the Cape Cod Canal are “fuel”
or power source
• Constant flow of ~5 mph
• Will generates electricity for
buildings on and near the pier
• Collaboration with public and
private entities
• Educational resource to several
energy courses

10. Center for Responsible Energy

• Water Conservation
• Aquaculture programs

11. “As a wide variety of adverse environmental factors continue to
affect quality of life and our ability to provide a quality education,
we will need to embrace the goals of sustainability and
accountability both as individuals and as an institution.
We will encourage the efforts of student organizations that raise
environmental awareness and initiate new techniques for achieving
environmental sustainability.
With a focus on these issues, we can make Massachusetts Maritime
Academy known for the quality of our environmental stewardship,
thereby attracting students committed to living in a resource
conscious manner and cultivate a willingness to involve all campus
members in the process of achieving greater campus sustainability.”
