The Dartmouth
Summary
Last spring, College President Sian Leah Beilock announced the Dartmouth Climate Collaborative — a $500 million campus-wide decarbonization project which aims to reduce carbon emissions by 60% by 2030 and achieve carbon neutrality by 2050. Related construction projects are now sweeping Dartmouth’s campus.
Senior vice president for capital planning and campus operations Josh Keniston said the College has been “transitioning from the design and planning phase [of the Dartmouth Climate Collaborative] to the construction phase.” Decarbonization projects — such as the installment of a new hot water heating system in front of New Hampshire Hall and Topliff Hall — were underway this summer and some projects will continue to impact campus this fall.
Instead of distributing steam heated through fossil fuel combustion, geo-exchange uses hot water for heating and chilled water for cooling, according to O’hern. To switch to this energy source, the College must build a central plant equipped with heat pumps that convert hot or chilled water into energy, he said. The energy is then distributed across campus through the new piping.
