Course Description

Provides a basic understanding of local residential greenroof design and installation. Covers greenroof benefits, best practices, material selections, and appropriate plantings; includes hands-on installation. Audit available.

Intended Outcomes for the course

  • Use targeted selling points to articulate greenroof benefits to customers, contractors and designers.
  • Apply basic greenroof design concepts that work in the Pacific Northwest climate to a construction project, including selecting a basic palette of local greenroof plants.
  • Design and construct greenroofs using appropriate roofing materials, greenroof layers and planting selections.

Outcome Assessment Strategies

  • €œSoak It Up€ Game: Students will work in groups and learn to identify pervious vs. impervious surfaces on a neighborhood map. Students will use basic budgetary skills to maximize the stormwater absorption while remaining within their allotted budgets.
  • Students will choose and categorize greenroof benefits related to an ecoroof case study. They will present these to the class for discussion. 
  • Each student will design a greenroof (in cross section,) and present it to the class, giving reasons for each design choice.
  • Students will heat weld small pieces of waterproof membrane, then test their own work in a procedure known in the trade as a €œtest weld.€   This is repeated until the test shows a successful weld.
  • Students will work in groups to complete 4 foot by 4 foot greenroof mockups that include waterproof membrane, drainage, soil and plants.
  • Students will participate in a greenroof tour of local greenroofs, and answer a written quiz. 
  • Students will complete homework assignments, quizzes and tests (mid-term & final) that will assess their understanding of the themes issues and concepts discussed.
