This campus greenhouse is powered by the sun—and student innovation

This campus greenhouse is powered by the sun—and student innovation Lauren Reuscher Wed, 04/23/2025 - 13:11 Body Gardening season is here, and those with green thumbs are preparing their planting strategy for the season. In any garden, plants need basic essentials to grow: sunlight, soil or nutrients, air, and water.  Through a new solar array at George Mason University’s Fairfax Campus, the sun will play double duty in the successful growth of plants. Solar energy will power the Presidents Park Greenhouse with the electricity it needs to support the plants growing inside.

A team of 10 George Mason student researchers applied for support from the Patriot Green Fund, an annual sustainability fund provided by Facilities and Campus Operations to make George Mason’s campuses more sustainable through infrastructure improvements. The Patriot Green Fund covers $20,000 of the total $185,000 project cost. The remainder of the budget is provided by Facilities and Campus Operations. “This student-led project is designed to reduce electricity costs, lower greenhouse gas emissions, and provide educational and volunteer opportunities for the George Mason community,” said Demin Zhu, Patriot Green Fund program manager with University Sustainability. The Presidents Park Greenhouse operates year-round and produces approximately 1,000 pounds of fresh lettuce and salad greens annually, which are served on campus at Ike's dining hall. Other fruits, vegetables, and herbs are donated to the George Mason community through free produce pickups.

They have the opportunity to learn about the greenhouse’s hydroponic and aquaponic food production systems. “The electricity from the solar panels will feed into the greenhouse to power our fans, pumps, cooling system, and grow lights,” said Doni Nolan, greenhouse and gardens program manager with University Sustainability. “The electrical equipment helps us grow lettuce, baby greens, tomatoes and more in the greenhouse to provide local sustainable ingredients to our dining halls.” The ground-mounted solar panels will be installed outside the greenhouse and are expected to offset more than 80% of the electricity it requires. The solar array is estimated to produce more than 22,000 kWh per year. The panels will reduce the building’s annual greenhouse gas impact by 13.8 metric tons of CO2, which is about equal to the carbon footprint of 2.2 typical single-family homes. The concrete pad under construction will accommodate the new solar array for the Presidents Park Greenhouse.

Vertical solar panels on the face of Fuse demonstrate how a solar array can be integrated into a building’s design in an urban setting. A vertical solar array requires less space and captures sunlight from multiple directions throughout the day. The array produces about 1% of the electricity used by the building and is part of a range of sustainable features that help Fuse meet LEED Platinum standards.  The installation at President’s Park expected to be complete by early June.  Crystal Bowers, BS Mechanical Engineering ’23, was one of the students who led the solar array project during her time at George Mason. “Working on the Solar Greenhouse Project was one of the most impactful experiences of my time at George Mason University,” said Bowers. “It not only deepened my understanding of sustainable infrastructure and project management, but also demonstrated the power of collaboration in transforming ideas into tangible, lasting change on campus.” Learn more about the Greenhouse and Gardens Read More Like This This campus greenhouse is powered by the sun—and student innovation April 25, 2025 George Mason students learn to tackle complex problems and engage with Virginia state senator March 14, 2025 Student organization recovers more than 1,600 pounds of food from dining halls, campus events February 21, 2025 Turning “trash” into treasure: diverting surplus property from the waste stream February 21, 2025 Breaking down the composting process January 23, 2025Topics Topics Campus News Sustainability Sustainability Patriot Green Fund University Sustainability mechanical engineering College of Engineering and Computing Mason as a Living Lab
