UNH implements a systematic and integrated energy policy that emphasizes health and integrity, climate protection, efficiency, cost-effectiveness and stability, fairness for all University constituents, and consistency with priorities set by the UNH Strategic Plan and UNH Campus Master Plan.
For over 25 years, the University of New Hampshire has explored and demonstrated renewable energy, energy efficiency, and climate adaptation strategies by engaging students, faculty, staff, and community members in a sustainable learning community. Faculty, staff, and students at UNH serve on the Energy Task Force (ETF) – created in 2005 to help guide reductions in energy use, energy costs, and greenhouse gas emissions on campus.
We're proud of UNH's track record on energy consumption and low carbon energy.
Energy is a critical part of our WildCAP plan. We are currently seeking comment and input on the elements of WildCAP 2021.

Our Energy Initiatives
UNH's combined heat and power facility, or cogeneration (COGEN), is the primary source of heat and electricity for the six-million-plus square foot Durham campus. COGEN retains waste heat normally lost during the production of electricity and instead uses this energy to heat buildings, in turn reducing sulfur dioxide and nitrous oxide emissions.
- Cost savings: UNH's COGEN, including a chilled water plant, cost an estimated $28 million - all self-financed - with an anticipated payback within 20 years. These savings incorporate the avoided costs of investing in the existing plant for needed renovations.
- Emissions savings: the installation of the COGEN plant resulted in an estimated reduction in greenhouse gas emissions of 21% in Academic Year (AY) 2006 compared to AY 2005.
In 2009, UNH began using processed landfill gas from the ECOLine project, a landfill gas-to-energy project that uses methane gas from a nearby landfill as the primary fuel for the COGEN plant, which provides electricity and heat for the main campus buildings
In partnership with Waste Management of New Hampshire, Inc., UNH launched ECOLine to pipe enriched and purified gas from Waste Management’s landfill in Rochester to the Durham campus. Coming from Waste Management’s Turnkey Recycling and Environmental Enterprise (TREE) facility in Rochester, NH; the landfill gas replaces commercial natural gas as the primary fuel in UNH’s cogeneration plant. Construction began in 2007 on the landfill gas processing plant in Rochester that purifies the gas and on the 12.7-mile underground pipeline that transports the gas from the plant to the UNH Durham campus.
UNH is the first university in the country to use landfill gas as its primary fuel source. When fully operational, ECOLine provides up to 85% of the campus energy.
- Cost savings: ECOLine cost an estimated $49 million - all internally funded - with an anticipated payback within 10 years of the project. Both the COGEN plant and the landfill gas projects were financed by the campus through borrowing.
- Renewable energy credits: In 2009, UNH began to sell the renewable energy certificates (REC's) associated with ECOLine's electricity generation to help finance the capital costs of the project and to invest in additional energy efficiency projects on campus. By selling RECs, UNH demonstrates fiscal as well as environmental responsibility.
- Emissions savings: When combined with the COGEN plant, ECOLine stabilizes energy costs, provides energy security, and demonstrates environmental responsibility. ECOLine and selling RECs are part of UNH’s aggressive climate action plan called WildCAP, which outlines how the university will lower its emissions to basically zero and secure its leadership position in climate protection as part of its broader sustainability commitment.
Renewable Energy Procurement
In 2015, UNH partnered with Community Hydro to purchase approximately 20% of the electricity that we purchase. In 2016, put arrangements in place to ensure that 80-100% of the electricity that we purchase comes from renewable sources like small NH-based hydro facilities, solar, wind or biomass.
UNH is proud to be a partner with the Department of Energy's Smart Labs Accelerator Program. By participating in this program, we commit to reducing energy use in labs by at least 20% over the next 10 years and implementing no-or low-cost measures in the shorter term.

Launched in 2009 with a $650,000 grant from the American Recovery and Reinvestment Act (ARRA), UNH’s Energy Efficiency Fund (EEF) has already seen more than $500,000 in energy savings “returns,” including over $250,000 in FY12 alone. The UNH Energy Task Force (ETF) estimates that after a decade, the university will realize about $3 million in energy savings and prevent more than 8,500 metric tonnes of greenhouse gases from being emitted - the equivalent of over 1,600 passenger vehicles or 19,000 barrels of oil.
How the EEF Works
The EEF is a “revolving” fund: savings from the energy efficiency projects are estimated using a combination of sub-metering and engineering estimates that follow the International Performance Measurement and Verification Protocol. Savings are captured through a System’s Benefit Charge (SBC) included in the utility costs charged to campus units. Thus a slightly higher rate offsets lower consumption due to the energy efficiency improvements and the net impact of funding the EEF on-campus units is cost neutral. Gas and electric utility companies recover similar costs from their customers using similar system benefit rate structures. The UNH Energy Office targets an average five-year payback on projects funded. Project selections are approved by the UNH Energy Task Force, which is comprised of administrators, faculty, staff and students from across campus.
The EEF has already invested in many projects, including:
- Efficient lighting retrofits across campus.
- Digital lighting controls in the main library.
- Insulating steam distribution piping.
- Upgrading a lab ventilation system in the engineering building. The building will also see one of the next investments, a passive solar heating system.
- Updated equipment in UNH's cogeneration plant.
- A retro-commissioning program which targets 5 to 20-year-old energy-intense buildings where we believe returning HVAC systems to peak performance can result in significant efficiency improvements.
History of EEF
Through the early 2000’s, steady investments in energy efficiency improvements had been made as the campus leveraged its own funds with rebate programs offered by the local utility companies. However, these programs became more restrictive concurrent with UNH investing in a combined heat and power plant to better utilize on-site energy, but which essentially eliminated any remaining eligibility for rebate programs. While renovation and new construction projects continued to require high-efficiency lighting, motors and HVAC systems, investment in pure energy efficiency projects stopped and campus energy use intensity (total energy per GSF) started to climb; an unacceptable trend for a campus with a strong culture of being “green.”
Campus energy managers, members of the Sustainability Institute, and the campus Energy Task Force (ETF) recognized that a dedicated funding stream for energy efficiency improvements was needed if the trend was to be reversed and the concept of an Energy Efficiency Fund (EEF) was developed. The fund would invest in energy efficiency improvements and the value of the estimated annual energy savings would be returned to the fund through a surcharge on the utility rate charged to campus units (UNH utilities operate as a cost center and charges campus units for utilities consumed.) This would replenish the fund and allow further investments. However, an initial source of funds needed to be found. After several unsuccessful initiatives, in 2009, UNH was able to secure a $650,000 grant of American Recovery and Reinvestment Act (ARRA) funds and the EEF was launched.
Several million dollars have been invested in retrofit projects across the UNH Durham campus, including high-efficiency lighting, motor, heating, and cooling, control systems; window upgrades; conversion of electric clothes dryers to natural gas dryers in residence halls; and conversion of domestic hot water conversions from electricity to natural gas.
- UNH uses LED lighting (Section 16510 Interior Luminaries of the UNH Planning, Design and Construction Guidelines). Choice of fixtures are made with the following considerations:
- Energy efficiency and sound rating
- Quality of lighting
- Ease of installation and installation flexibility
- Ease of maintenance
- Suitability for the specific application
- Replacement parts availability
- Consideration of potential abuse
- UNH has moved away from exterior metal halide fixtures and has identified LED replacements as the new choice for walkway, street, and building exterior fixtures.
- UNH uses VendingMiser® technology in vending machines. Maintenance savings is generated through reduced running time of vendor components, estimated at $40 - $80 per year, per machine. Energy consumption is reduced an average of 46% -- typically $150 per machine annually.
Electric hand dryers in restrooms are our campus standard for new construction and renovation. UNH is also working to escalate retrofits from paper towels to hand dryers where feasible.
