Action Step for Designing a Green Roof Solution

Incorporate what you’ve learned about green roof technology, urban heat islands, and managing heat transfer through green roofs. You will do this in the form of writing an engineering document known as a Request for Proposal (RFP) that proposes a green roof solution for an urban building. You will describe it in words, pictures, and data graphics.


Site Context:

You are part of an engineering team competing to win a new client who wants a green roof built on the roof of hypothetical urban apartment rowhouses located on Clinton Street, between Sixth Avenue and Vine Street in one of New York’s five boroughs, Brooklyn. Our hypothetical building looks similar to the real neighborhood you can see at the Fort Greene/Clinton Hill Rezoning (http://www.nyc.gov/html/dcp/html/ft_greene/index.shtml). The building unit you are to plant is 50 feet tall, 50 feet wide, and 100 feet deep, backing up to an alley. There are five brownstone rowhouses connected in the unit you are considering, all of the same dimensions. You are only planting one row house with a green roof. The client has issued a Request for Proposal, called an RFP. This is a formal engineering document.

Your Job:

Working in teams, submit a design for this green roof that includes the following RFP elements:

1. No more than two pages of double-spaced, 12-point font, written text answering the following questions:

a. site description of the building, neighborhood, climate
b. statement of problem green roofs address
c. advantages of green roofs
d. drawbacks of green roofs
e. recommendation of methods to use to build a green roof—which of three main types we discussed in class (a list of plants to use is optional)

2. One drawing of the site. This is a form of visual information that concisely conveys the building’s context, as well as your proposed green roof. The context includes information such as streets, neighboring buildings, their size and type, and the building in question, with proposed dimensions of the green roof; perhaps a cross-sectional drawing of the construction of its green roof, such as those included in the Waitakere City Council's Green Roof Information book (http://www.waitakere.govt.nz/abtcit/ec/ecoinit/pdf/greenroof-informationbook.pdf) which offer just one way to approach a cross section; and perhaps photos/drawings of plants you suggest be planted.

3. One data graphic, such as a schematic cross section. See Green Roof Technology (http://www.greenroofplants.com/green-roof-technology/) for more information. Other data graphics are possible too. Remember to label all units, sections, each axis if you use a scatter plot, and to title the graphic.

When you are finished with the RFP, discuss with the class ways to present them. Options include:

  • A team by team presentation, which may include PowerPoints.
  • Each team mounting text, images, and data graphics on exhibit boards and setting them up in a space in which all team members can walk to review each other’s work.
  •  Your ideas!

Whatever method is chosen, each student must choose two teams’ exhibits to evaluate with a rubric for completeness of RFP—and award the “contract” based on the evidence cited in the rubric.
