Green Roof at Summit United Methodist Church - Service Learning Project

  1. 1. Our purpose in this research is to provideinformation on various green roof systems,the maintenance involved, and how tosecure funding for the implementation of aGreen Roof at The Summit UnitedMethodist Church.
  2. 2. 1.  General Benefits of a Green Roof2.  Benefits of comparable modular tray systems a)  Live Roof b)  Green Roof Block c)  Carlisle/Green Grid Systems3.  Maintenance Plan4.  Rainwater collection feature5.  Green Wall option6.  Cost7.  Alternatives to a green roof8.  Funding9.  References
  3. 3. •  Decreases heating and cooling load –  Increases thermal resistance value of roof and cooling roof by evaporation•  More than doubles life of roofing membrane –  Protects membrane from harmful UV rays, punctures, and extreme temperature fluctuations
  4. 4. •  Reduces the amount •  Michigan State of storm water runoff University Study from a building’s roof•  Materials absorb rain water and releases it over time•  Plants filter pollutants creating cleaner runoff Green roof water amount retained: 60-100%
  5. 5. •  Support local wildlife –  Increases amount of local plants –  Cuts down on lost vegetative space –  Encourages biodiversity
  6. 6. •  Implement an outreach program within the church –  Community volunteers giving back –  Create a sense of self-worth and pride –  Helps a nonresidential building blend in with the neighborhood –  Improves aesthetics of neighborhood

  10. 10. •  Maintenance –  Annual soil testing and Fertilization –  Watering when less than 1” of rainfalls during a 2 to 4 week period when it is 75 degrees or hotter –  Biweekly weeding during Spring and Fall growing seasons –  $0.15 to $0.30 annually liveroofs.com

  11. 11. •  Carlisle Protection Fabric ( CCW-200V) –  Installed directly on exiting membrane roof•  Planted Modular Trays –  24” x 48” –  24” x 24”•  New roofing membrane application would be needed before this system or other green roofs systems were installed to keep the existing roof warranty
  12. 12. •  Maintenance Plan –  Despite such claims, there is no such thing as a maintenance-free green roof. –  Do not let your maintenance plan go ignored
  13. 13. •  Maintenance Contracts –  3-5 years –  Typically established with the green roof installer, who –  Installers most likely cover the warranty of your green roof
  14. 14. •  How Frequent? –  During establishment period (18-24 months) •  4-6 routine maintenance visits are required to insure survival of the vegetated cover –  Establishment period will be less with pre-vegetated modular trays (Live Roof).
  15. 15. •  Watering –  The plants selected for a project should be drought tolerant. –  Periodic hand watering during the establishment period and afterwards but only in sustained drought•  Drainage –  Visually and manually check drains for clogs every 4-6 months
  16. 16. •  Weeding –  Every 4-6 months after establishment period recommended –  Hand pruning should be used •  No digging or using pointed tools•  Fertilizer –  Soil tests should be conducted each spring in order to assess plant nutritional requirements. –  The nutrient applications should be made in early spring and fall.
  17. 17. Rainwater Data Tank Specs•  1000 ft² = 623 gallons •  $315 (on sale for $206) –  1 inch rainfall •  305 gallons•  1700 ft² = 1059 gallons •  Diameter: 46 inches (Approximate) •  Height: 49 inches•  Need: 4 tanks to hold •  Weight: 64 LBs optimum water storage
  18. 18. •  Each tank empty = 64 LBs•  305 Gallons x 8.35LBs/gallon = 2546 LBs•  2546 LBs + 64 LBs = 2610 LBs per tank•  Weights –  1 tank: 2610 LBs –  2 tanks: 5220 LBs –  3 tanks: 7830 LBs –  4 tanks: 10,440 LBs
  19. 19. •  Modular tray system attaches to wall•  Growing medium included•  Can use reclaimed water
  20. 20. •  Modular trellis system•  Can be wall hung or freestanding•  Plants typically grow from base of wall and vine up the trellis
  21. 21. Stage 1: Outlined in yellow, isapprox. 1160 ft² • Improve HVAC operation by reducing heat island effect on roof. • Approximately 10% of section is occupied by equipment.Stage 2: Outlined in red, isapprox. 1600 ft² • Provide additional benefits described previously.
  22. 22. •  Modular –  Live Roof- $20/ ft² –  Green Roof Blocks - $25/ ft² –  Green Grid System (Carlisle) $12.50 to $ 13.00 per ft²•  Conventional –  Tremco - $15-25/ ft² –  Greenscapes - $8 - $10/ ft²•  Green Wall - $9-$12/ ft²•  G-Sky wall system $100 or more/ ft²•  Leak detection - Electronic Vectormapping $0.75 / ft²•  (4) x 305 gallon water cisterns - approx. $824 ($206 each)•  Reflective roof ranges from $0.75 to $3.00/ ft²
  23. 23. •  Reflective coating applied to existing roof•  Helps keep roof cool by reflecting sun’s rays back into space•  Can reflect 80% of sun’s rays and reduce roof temperature by up to 80 degrees
  24. 24. •  Cost and Maintenance –  $0.75 to $3.00/ ft² for materials and installation –  Extends life of existing roof up to 15 years –  Requires little maintenance (occasional cleaning or reapplication)
