This project is in conjunction with the Mulberry Center on Lincoln and Mack. The first 1-2 domes will be attached to their center for community needs
The geodesic dome presents ideal solutions to greenhouse problems. Sun enters glass best at certain angles. Most greenhouses with glass arranged in a 1-2 directions fail to absorb the sun for large portions of the day, and too much sun when it actually is properly aligned. They have peak sun hours, and low points. By using the dome you maximize the sun absorbed by presenting different angles because sunlight can enter at all times of the day. This avoids the overheating periods that greenhouses can have. The geodesic dome design provides for a homogeneous amount of sun to enter throughout the day.
Dome building is cheap compared to building a greenhouse. The lumber for the struts costs about $220 for enough to build 3 domes, with each additional dome costing $40 in lumber. Additional costs are likely to be around $25-60 per dome. To build 3 domes, a minimum target of $325 should be expected. By contrast, for $1,000 15 domes could be built, as one of the major costs of dome construction is the shipping associated with the bamboo. Even better, many of the materials could be directly donated.
Around these greenhouses coniferous bioremediators will be planted. These will cool the greenhouse in the summer, and warm it in the winter, bioremediating and enriching the soil year round. These plants can be purchased for $25 a piece and later grown and produced in the greenhouse to save future costs.
When attached to a brick wall, there are many benefits for the geodesic dome and the building to which it is attached. They can share heat and humidity back and forth weather conditions change saving on heating and cooling costs. Also, home air quality and humidity would increase, possibly reducing the incidence of respiratory infections. Likewise greenhouse humidity would decrease lowering the incidence of plant diseases.
The dome would have a square footage of more than 50 feet. A commercial greenhouse built to be the same size could cost more than $10,000. These kits may have extra mechanical advantages such as an automated ventilation system, but on the whole a conventional lean-to could cost more than 60 times as much as a comparable dome model.
This project is based on Buckminster Fuller geometry, but is a unique design. All blueprints, techniques, and results will be publicly accessible upon project completion at www.DetroitBioremediation.org
