Sustainable Greenhouse Design

Rocky Mountain Gardening Elective

Have you ever wondered if it could be done? Can you create a greenhouse that needs NO SUPPLEMENTAL HEATING OR COOLING YEAR ROUND? The answer is yes!!

No more over-heating and freezing as is common in all-glazed greenhouses – this design balances the use of thermal mass, glazing, insulation and sun angles to achieve the stabilization needed in our extreme climate without the use of fossil fuels.

You will learn how to design a sustainable greenhouse from the ground up using salvaged or new materials, or in combination to achieve the look and performance you want. You can also use these techniques to improve an existing greenhouse.

This class is a comprehensive look at how passive solar greenhouses work, it includes how to orient the building, basic principles of passive solar design including the use of stored water as thermal mass, simple math formulas to help guide you with your design, a materials list and drawings and calculations for a 13’X15’ greenhouse.

In 2000, the Parmenter’s built their first greenhouse out of 90% recycled materials on top of an 8,120 ft. decomposed granite mountain. Since then, they have designed and built many more and are ready to share what they’ve learned about state-of-the-art materials and cost-saving strategies.

C’mon, walk through the snow into your warm, inviting greenhouse and lose yourself in a year round garden sanctuary.
