Energy & Water
Denison recognizes that energy and water conservation are key to becoming a more sustainable campus. The college is currently in the process of installing smart meters on its buildings so that current energy use can be monitored, giving the Facilities Department and building occupants opportunities to reduce energy use.
As buildings and spaces are renovated, Denison makes every attempt to install energy & water-saving technologies such as light and motion sensors, Energy Star appliances, energy-efficient HVAC systems, low flow plumbing fixtures, dual flush toilets, and waterless urinals.
Renewable energy also has a prominent role on campus. Denison’s alternative living site, the Homestead, has been using solar panels for decades to produce power for the 12 student residents that live there year-round. In 2007, through a gift from John Hunting ’54, Denison installed a solar array on the roof of the Library.
Doane Library Solar PanelsThanks to the generous donation from Mr. John Hunting (1954), founder of the Beldon Fund, and the monies granted by the Office of Energy Efficiency at the Ohio Department of Development, solar panels have been successfully installed on the roof of the William Howard Doane Library at Denison University. They can be seen from the south-facing window of the reading room on the fifth floor of the Stacks in the Library and from the west-facing windows on the top floor of the Fellows Building.
The photovoltaic panels, or solar panels, were installed by a company contractor, Third Sun Solar and Wind Power, in April 2007 but were not fully functional until August. As part of the green renovations to Barney-Davis completed in 1998, a conduit connecting the Barney-Davis electrical circuit to the Doane Library was established in an effort to plan for future solar panel additions. Since the electrical conduit was set in place, Barney-Davis was ready to accept energy generated by the Library solar panels once they were operational.
The array of solar panels can generate up to 6,440 direct current Watts of energy. In November 2007, the panels produced a maximum of 27.5kWh/day of energy. Between August and December, the total system output reached 1,343.4kWh preventing 2,712 lbs of carbon dioxide emission.
Our students also are involved with energy conservation through annual intercollegiate sustainability challenges:
Water WarsEach year, during the Fall, Denison students living in the residence halls participate in a friendly campus competition called Water Wars. This water conservation competition pits dorm vs. dorm to see which can reduce its water use the most. The Green Team, a campus environmental organization, and the Physical Plant sponsor the competition.
The main reasons behind water conservation and this competition are threefold:
- Economic -– In the 2011-2012 school year, Denison used over 37 million gallons of water at a cost of $362,265.
- Environmental -– Clean water is a valuable resource to both the local and global community. As the effects of climate change are realized, the demand for fresh water will increase and put a strain on both ecosystems and communities.
- Personal -– Learning about water conservation and one’s individual environmental impact is a critical step in making positive personal behavioral changes that can benefit everyone.
The best way to get involved is to work with the Green Team campaign to reduce our environmental footprint. To volunteer, contact the Green Team.

Greenhouse Gas Inventory
Denison recently conducted a greenhouse gas inventory using the Clean Air - Cool Planet model. This inventory creates baseline data from 2005 that will allow Denison to track its emissions and to develop strategies to reduce emissions of greenhouse gases in the coming years.
