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.

  • Massachusetts Department of Food and Agriculture Agro-Envronmental Technology Grant Program provided funding for some of the untried aspects of our greenhouse.
  • 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 reference material.
  • 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 the greenhouse.
