Many wonderful people and organizations contributed to this
project. It is not hyperbole to state that this project would not have
been possible without them.
Department of Food and Agriculture Agro-Envronmental Technology Grant
Program provided funding for some of the untried aspects of our
- Sustainable Agriculture
Research & Education Program, Northeast Region provided funding
for some of the design work and testing.
- Mark Rosenbaum of Energysmiths
provided engineering and design consultation, and helped us to understand
how to think about our project. Marc is a simply a genius who understands
both the theory and practical issues of energy-efficient construction.
He's got a quick mind and an incredible memory; ten hours of work gets
done in one hour with Marc.
- Dave Vreeland of Spectrum Design
Collaborative engineered the greenhouse frame. Dave has a knack
for synthesizing various design goals, constraints, and practical considerations
into a cohesive package that fits. He thinks about all the little details
without losing sight of the big picture. (And, he's a really nice guy.)
- Allen Barker of the Department of Plant and Soil Sciences at the Univ.
of Massachusetts was generous with his time and expertise in hydroponics.
- David Hansen of Memphremagog Heat
Exchangers provided the materials for the HRV core. He also recommended
the amount of HRV core that would be needed for our 500 CFM exchange
rate, and generously took the time to sketch and describe how the HRV
should be constructed.
- Dick and Rob Hillman of W.R. Hillman and Sons of Shelburne Falls,
MA did all the site work for the project including installing the earthtubes
and the stone in the rock bed. The did all their work with great care,
and as is typical with them, thought of and resolved many issues that
I should have thought of but didn't.
- Franklin County Fabricators of Greenfield, Massachusetts fabricated
the frame. They cooperated with the engineer during the design phase,
and cared about the finished product.
- Rugg Lumber in Greenfield, Massachusetts supplied all of the standard
construction materials, and was consistently helpful in brainstorming
untraditional applications of traditional materials.
- John Bartok, professor emeritus of greenhouse engineering at the University
of Connecticut, reviewed our plans and made many useful comments.
- The NESEA (Northeast Sustainable
Energy Association) library was a helpful source for some out-of-print
- Ellen Shukis, Director of the Mt. Holyoke College Botanic Garden,
was generous with her time and her expertise on greenhouse cultural
requirements of subtropical plants.
- Ed and Eddie Diemand were a godsend during the greenhouse construction.
I have never met anyone who works as hard as they do.
- Steven Breyer of Tripplebrook Nursery (Easthampton, MA), Phil Maddern
of the Gill Greenery (Gill, MA), and the folks at Natick Community Organic
Farm (Natick, MA) generously allowed us to tour their greenhouses, and
shared their experiences.
- Celluspray Insulation of Shelburne Falls, MA did a careful job packing
in as much cellulose as the walls would bear.
- Lee Edelberg (and Tristan) electricians did a thoughful job wiring
