Climate & Energy

Capital Partner Solar Project

GW was the first school in Washington D.C. to sign the American College and University President’s Climate Commitment (ACUPCC). As a signatory of the ACUPCC, GW is committed to reducing its carbon footprint and to measuring its greenhouse gas (GHG) emissions. The university released its Climate Action Plan in May 2010 and in the plan targets carbon neutrality by 2040, and a 40 percent reduction in its cumulative carbon emissions by 2025 relative to a 2008 baseline via a mix of energy reduction & conservation projects, utility supplier fuel mix changes, on-site renewable energy generation, transportation reduction initiatives, and sustainable procurement practices.

GW's Climate Action Plan uses the framework of “Reduce, Innovate and Partner” to address carbon emissions. The links below provide access to more information about how we aim to reduce our greenhouse gas emissions and achieve carbon neutrality.

Climate and Energy

Renewable Energy

As an urban university in downtown Washington, D.C. with limited rooftops and open space, GW had to get creative in sourcing a large amount of renewable energy. The university developed an innovative solution to improve the environmental impact of its electricity consumption – Capital Partners Solar Project. The project generates approximately half of GW’s electricity from solar farms in GW’s grid. This accelerates GW’s pace towards reaching its 2025 carbon reduction goal by nearly 25% compared to the 2008 baseline.
 
GW created the Capital Partners Solar Project in partnership with American University and the George Washington University Hospital, with support from CustomerFirst Renewables. Duke Energy Renewables developed 500 acres of solar farms in northeastern North Carolina. The farms are split across three sites but are located in proximity to one another. The system size was based on the partners’ joint request for 121,000 megawatt hours (MWh) of solar photovoltaic (PV) electricity annually – roughly the amount of energy used by 8,900 U.S. homes every year.
 
The solar farms’ cumulative 53.5 MW capacity represents one of the larger solar PV projects east of the Mississippi. Together, the partners will purchase more than 2.3 million MWh of solar power over a 20-year period. GW is the largest purchaser, buying approximately 70% of the system’s solar energy output. For GW, this will result in an estimated 30% reduction of its carbon footprint. 
 
The project's total combined purchase size, as well as that of GW’s portion alone, was the largest non-utility power purchase agreement for solar power in the country (as measured by total contracted MWh over the length of the term) at the time of signing in 2014 according to the U.S. Environmental Protection Agency’s Green Power Partnership.

Closer to home on its Foggy Bottom campus in Washington, D.C., GW also installed four solar thermal hot water systems on campus residence halls: Shenkman Hall, 2031 F Street, 1959 E Street and Dakota Hall. These systems offset natural gas consumption and provide hot water heating to student residents. GW continues to explore other sites for renewable generation on both existing and new buildings. As part of its Climate Action Plan, GW is committed to using its campus as a test bed for new technologies that will help reduce our carbon footprint.

 

Energy Efficiency

To help achieve its Climate Action and GWater Plan goals, GW will rely on comprehensive energy and water efficiency plans. To date, GW has launched four, large energy and water efficiency projects known as the Eco-Building Program. In Fall 2011, the university's Innovation Task Force, a committee launched by President Steven Knapp in 2009 to identify cost savings and new revenue for reinvestment in the university’s top academic priorities, accepted the idea for the Eco-Building Program. The university’s Facilities Services and Office of Sustainability are implementing and managing the Eco-Building Program in phases, a few campus buildings at a time.

 

The Eco-Building Program has been installing more modern and efficient equipment in selected buildings to reduce energy and water use, operating costs, and greenhouse gas emissions.  These initiatives include: more efficient use of potable water; upgrading old HVAC equipment like boiler controls, chillers, and air-handling units; adding new HVAC equipment like variable-speed drives and variable-air-volume boxes; retro-commissioning older HVAC equipment; and installing more energy-efficient lighting and controls.  These projects are being developed using a holistic view of savings opportunities across campus.  Phase 1 focused on the Gelman Library block of buildings.  Phase 2 focused on the Lisner Hall block of buildings.  Phase 3 focused on Rice Hall, Marvin Center, and Funger and Duquès Halls.  Phase 4, which is about to begin, will include four buildings at the Virginia Science and Technology Campus.  The Eco-Building Program includes implementing a SCADA system for the Foggy Bottom Campus, including the Central Utility Plant, and an energy dashboard.

 

GW also leverages the annual Eco-Challenge to help unite the student community in conservation. In summer months, GW also participates in demand response programs to help alleviate pressure on the electric grid during peak usage hours.

 
 

 

Solar Walk

Solar Walk links Exploration and Innovation Halls on GW's Science & Technology Campus (VSTC) in Ashburn, VA, through innovative solar technologies including a trellis with photovoltaic panels that supplements electricity for lighting. An installation of ‘walkable’ solar panels is also being tested. Landscape elements include 100% native plant materials, multiple rain gardens, permeable pavements, bioswale, and rainwater collection from trellis roofs. The Solar Walk is part of the VSTC's expansion of its academic programs and physical presence.
