Total energy consumption (all sources, excluding transportation fuels), performance year :
Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
A brief description of on-site renewable electricity generating devices :
23.8 kW photovoltaic system on Sophia Gordon Hall, installed in 2006. This is the one solar installation for which Tufts retains or has retired the associated environmental attributes. 85.3 MMBtu is equivalent to 25,000 kWh that is estimated to be generated annually by this solar installation.
In addition, we have the following on-site renewables, for which we do not retain the renewable energy certificates (RECs):
- 99 kW photovoltaic system on Dowling Hall, installed in 2014.
- 2.5 MW DC PV system built on eight acres south of the Bernice Barbour Wildlife Medicine Building on Grafton campus.
- Approximately 1.27 MW DC PV system on four acres near Grafton Science Park, both Grafton projects installed in 2017.
Sunbug Solar, the company that installed the Dowling solar panels, also provided $10,000 to fund the construction of a student-designed solar installation on campus that can charge portable electronics. This project was installed on Hodgdon Hall during fall semester 2018 with help from the Green Fund.
In 2018, Tufts entered into power purchase agreement with Solect to install solar panels on Lewis Hall, the Science & Engineering Complex, and potentially some other sites. The agreement assigns the RECs to Solect in order to provide a lower electricity cost to Tufts.
Non-electric renewable energy generated on-site, performance year:
A brief description of on-site renewable non-electric energy devices:
Sophia Gordon Hall hosts a roof mounted solar thermal system to supplement the gas-fired domestic hot water system used in the residence hall.
Schmalz House has two solar thermal panels for supplemental domestic hot water and a small photovoltaic panel to run the system pump.
There is no meter on either system. We are simply burning less fossil fuels to create hot water.
Total clean and renewable electricity generated by off-site projects that the institution catalyzed and for which the institution retains or has retired the associated environmental attributes, performance year:
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
Total third-party certified RECs, GOs and/or similar renewable energy products (including renewable electricity purchased through a utility-provided certified green power option) purchased during the performance year:
A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:
Purchased RECs from 3 Degrees on 8/17/2009 for LEED projects.
