Help us to build a green roof at Brown!

Thankfully, our structural engineer determined that 50 John Street poses very few structural limitations for this project. The building can hold a great deal of weight and thus has incredible potential for a successful green roof. The remaining limiting factor is funding. The scale and scope – and thus the success – of our undertaking will largely depend on the support we receive from groups like yours. Because we plan to implement this project at whatever scale possible, we have developed potential plans for several projected budgets, all of which are dependent on raised funds:

  • at $500: Roof completely funded by a donation from the Brown University Sustainable Food Initiative. Project limited to several shallow planters of untreated pine wood (with a maximum lifespan of 4 years). Planters used to grow salad greens only, as a continuation of SUFI’s current partnership with Brown Dining Services.

      Coverage: 10% of target area (Goal: coverage of half of roof)

      Visual Impact: negligible

      Impact on Environmental Efficiency of Building:  minimal to none

 

  • at $2,000: Project consists of vegetable planters out of pine (max. lifespan 4 years) and minimal ornamental grass coverage (less than 200 sq. feet). Beds remain limited to cultivation of SUFI produce. As impact on Environmental Efficiency of Building is directly correlated to square footage of grasses, the efficiency impact remains minimal at this funding level.

      Coverage: approx. 500 square feet, about 25% of target coverage

      Visual Impact: negligible

      Impact on Environmental Efficiency of Building:  minimal

 

  • at $5,000- $8,000: Project extends to include a greater number of shallow vegetable beds, with a variety of produce in each bed. Produce now not only devoted to SUFI partnership, but is also sent to Market Share program. Taller plants which can be seen from the street, such as sunflowers, will be added. Beds still constructed out of pine wood (4 year life span). Extensive cover of grasses.

      Coverage: approx. 1,000 square feet, about 50% of target coverage

      Visual Impact: intermediate

      Impact on Environmental Efficiency of Building:  reduces winter heat loss by about 5%, reduces storm water runoff, covers enough area to extend lifespan of roofing materials already in place.

 

  • at $8,000- $10,000: Project expands significantly, with the addition of several more vegetable beds (potentially out of Cedar wood with a 25-30 year) and increased grass coverage. Vegetables beds can include increased variety of produce including fruit trees. Garden space consists of minimal landscaping and becomes an ambient green space for visitors.

      Coverage:  approx. 2,000 square feet, 100% of target area

      Visual Impact: significant (due to fruit trees, trellising, taller crops)

      Impact on Environmental Efficiency of Building:  significant reduction of heat loss, storm water runoff, and considerable extension of life of roofing materials.

 

  • at $10,000 +: Funding level allows for an almost complete coverage of grasses for maximum impact on building’s environmental efficiency. Vegetable beds are constructed of Cedar wood and include SUFI produce, herbs, extensive vegetable cultivation, fruit trees and flowers. Considerable landscaping to make roof an approachable space to visitors.

      Coverage:  approx. 4,000 square feet, 200% of target area (exceeds goal!)

      Visual Impact: extremely significant not only from the street but also from roof level (due to landscaping)

      Impact on Environmental Efficiency of Building:  significant reduction of heat loss, storm water runoff, and considerable extension of life of roofing materials.

 

            We’re committed to this project and will pursuit it at any level of funding. However, we hope that given the opportunity, our community will help make College Hill’s green roof as significant a local presence as possible. Please consider supporting our project, and College Hill’s sustainable future, in any way you can.
