A bioshelter can play a lot of roles in a sustainable culture. In addition to expanding the production of a market garden, a bioshelter provides a place for education, social gatherings, and general relaxation. Not everyone needs to garden, but we all need to know a gardener. Neighborhood greenhouses / bioshelters will provide plant material, seedlings, herbs and produce and a green space to socialize in cold months. The colder the climate, the more need there is for sheltered environments to grow greens in the cold seasons. In keeping with permaculture design, making thses places serve multiple functions in the community magnifies their "productivity". The thermal mass in bioshelters also can be multifuntional, from fermentation vats, producing miso, kim chi or wine while stabilzing greenhouse temerpatures.
Many buildings, cafes and restaurants can incorporate bioshelters in their roofs and buildings to provide fresh ingredients and extend the season for fresh local produce.
