MEP Associates, LLC (MEP) provided mechanical, electrical, plumbing, and geothermal engineering design services to Carleton College during its Utility Master Plan and Building Conversion project.
MEP worked with the campus to develop its 2016 utility master plan, which assessed the existing systems and made recommendations for new technologies to help the college reach its long-term goal of carbon neutrality. These recommendations are being implemented in a multi-year, multi-phased campus conversion project.
By the design of MEP, the existing gas-fired boilers and high-pressure steam distribution piping will be replaced with a 120°F heating hot water system, served by a new geothermal system comprised of a water-to-water heat pump and a series of geothermal borefields located throughout campus. The new geothermal system is capable of providing simultaneous heating and cooling and will be sized to meet the campus’ continuous heating and cooling demand. New high efficiency gas fired boilers will be installed to address the peak heating demand, and the existing chiller will remain in service to address the peak cooling demands.
In its 2011 Climate Action Plan, Carleton College pledged to become a carbon free campus by 2050. It will be the first college campus to completely transition off steam and will be the first college campus to install a district-energy scale geothermal system.
