While the benefits are numerous, a durable, insulated greenhouse is a larger endeavor than an outdoor learning garden or simple hoop house. A passive solar greenhouse relies on solar energy as much as possible to keep the greenhouse warm enough to grow year round. (Standard greenhouses, in contrast, have a high heating/cooling load that can be a cost burden for a school for years to come). A solar greenhouse also adds to sustainability initiatives, setting a school apart as a green-minded institution. Using passive solar greenhouse design, the school greenhouse is a durable and insulated structure. It is engineered and designed to withstand local snow/wind loads. A Ceres greenhouse becomes a permanent and beautiful extension of the school.March 2015- An Idea Is Born
Bill Martin, a biology teacher and outdoor educator, articulates the scope and formal plan for the construction and incorporation of an aquaponic and organic greenhouse into the Pomfret School program and presents it to school administrators who become partners in the effort to apply for grants and raise money for the project.
Brian Geyer, a Pomfret School physics teacher with construction experience, partners with Bill Martin in a shared vision of a greenhouse that could simultaneously support hands-on learning in science and engineering, teach kids how to grow food, build community, and produce food for Pomfret School’s dining hall and a local food bank. They travel to Longmont, CO, to attend a Ceres and Aquaponic Source two-day course to learn the basics of designing and building a passive solar greenhouse.
Fall Term 2015- Students Become Involved
looking to involve students, Martin and Geyer create a greenhouse design course.
Simultaneously, the Director of Advancement works with the Chief Academic Officer and Bill Martin to fundraise for the greenhouse, sending out grant applications to foundations that would be interested in supporting a project with the sorts of learning goals, teaching methods, and community impact that our project proposed. Bill Martin creates a YouTube video to explain the project to apply for a B. Good Family Foundation grant. While the Helios Project came up short as a finalist for the grant, the video served to spread the word about the project to the broader Pomfret School community and beyond.
December 2015- The Helio Project is Created
December 2015 – Bill Martin facilitates a group of students that name The Helios Project, design a logo for it, and build a website to document the project’s mission and progress. See it at helios.pomfretschool.org.
May 2016- Building Permits are Acquired
Pomfret School applies for and receives a building permit from the town of Pomfret to construct its greenhouse. Students and adult partners accompany engineering consultants from CME Engineering to a Town of Pomfret Planning and Zoning Committee meeting to present the project and gain approval.
Spring and Summer 2016-
With the basic greenhouse design in place, Bill Martin, Brenda Bullied (Pomfret School’s Director of Facilities and other partners), and CME Engineering consultants work with Ceres to create a final greenhouse design using their commercial metal frame greenhouse kits – called the HighYield Greenhouse – to configure it to the Helios Project’s purposes.

July 2016- Construction
Construction begins. Thankfully, Brian Van Way, Pomfret School’s Ceres Greenhouse Solutions project manager, worked with our group at the very beginning to build and erect the trusses and get us started on installing girts and purlins – this was incredibly helpful. To move the project along, Pomfret campus professionals, Todd Milanese and Todd Lemire, along with Michael from Ceres, installed the remaining IMPs to finish the knee walls and create the east, west and north walls, as well as the windows and doors and polycarbonate walls and roof by summer’s end, 2017.
Fall, Winter and Spring Terms of 2016/2017- Aquaponics Integration
The Engineering a Controlled Environment classes, later named “Sustainable Engineering: Aquaponic Systems,” worked on designing, building, operating and refining the three aquaponics systems that will be used in the greenhouse.
Major milestones reached in the 2017-2018 school year included:
- The design and construction of the first large aquaponic system was completed and went live in December, accepting 75 tilapia from a previously built system used to raise fingerlings; it achieved full production of produce two months later.
- Through the winter and spring, harvests of tomatoes, green beans, lettuce, cilantro and basil were shared with the dining hall, a local food bank, and Pomfret School families and students.
- In May, 100 tilapia were filleted by a large volunteer group of students and faculty and were part of a fish fry dinner in the dining hall that also featured a greenhouse grown tomato and basil salad.
School Year of 2018-2019- Plans for the Upcoming Year
The goal of the Sustainable Engineering: Aquaponics and Advanced Environmental Science classes will be:
- Complete the fish tank platform and plumbing for the second aquaponics system
- Build the third aquaponic system
- Fill and plant the organic soil bed, adding greater capacity to the greenhouse’s production

Fall Term of 2019 Onward-
The Helios Project passive solar aquaponics greenhouse will serve as a hub of activity serving the Pomfret School and surrounding community in a wide variety of ways. Flowing from the Helios Project’s greenhouse design theme of “planned imperfection,” the greenhouse’s uses will include:
- Student aquaponics system research and engineering design
- Building opportunities focused on solving emerging challenges and enhancing the entire greenhouse’s operation
- Development of a student-centered year-long Honors Biology class around the aquaponics and organic soil systems
