3. Introduction 3

4. Objectives 4 Make a positive impact to the environment Serve the large percentage of students interested in sustainability Increase Anderson’s reputation as a sustainable school

5. Our Approach 5 Make a measurable impact Positive Impact on the Environment Implement a concept that will excite and involve the Anderson Community Serve Student Interest in Sustainability Utilize the Anderson Campus to make a visible impact Make Anderson a Green Business School

6. Solution 6 Green Roofing Anderson – Covering the Anderson Roofs with vegetation and soil planted over a waterproofing membrane

7. Why this is the best Option for the Roof 7 AlternativeBenefitsHurdles Green Roof-Reduced urban heat island effect -Reduced energy usage & cost -Reduced renovation cost -Large upfront costs Reflective Roof-Reduced energy usage & cost -Cost effective - Lower energy savings - Does not have additional environmental impacts Solar Paneled Roof-Use of alternative energy -Reduced fuel cost -Reduced dependence on foreign oil -Large upfront costs -Anderson has deemed solar panels infeasible and will not consider this as an option for implementation within a year Future Considerations: In the event that Anderson decides to invest in solar panels, green roofs increase the effectiveness of solar panels

8. Project Proposal 8

9. Green Roof Type Extensive – 1-6 inches of soil – Ground cover or shrubs – 15-50 pounds per square foot – Can be either Modular or Integrated (Built-In) Intensive – 6-24 or even more inches of soil – Extensive assortment of plants (trees, shrubs, public spaces) – 80-150 pounds per square foot – Must be integrated 9

10. Green Roof Type Analysis CriteriaExtensiveIntensive Ease of Installation Weight Considerations Amenity Space Plant Variety Maintenance Price 10 Result: Extensive Modular Green Roof Implementation

11. Location Considerations Requirements For Prototype West facing building higher energy usage Free space least amount of structural disturbance in the roof (sky lights, pipes etc.) 11 Added Benefits of Building F High Visibility Visible from top floors of other buildings Above the Dean’s office

12. Vegetation 12 Requirements – Ability to grow under the conditions of the green roof – Climate – Soil Level – Tolerant of drought conditions Recommendations – Succulents (ex. Sedums) – Work with green roof provider Irrigation System – Efficient Drop Irrigation

13. Benefit & Costs 13

14. Air Quality Improvement 14 Particulate matter reduction due to a 1000 ft 2 green roof = 40 lbs Particulate matter reduction at Mullen Commons = 199 lbs Particulate matter emitted by one car in a year = 2.67 lbs That is a reduction of particulate matter from 75 cars or the cars of ONE Anderson MBA Section a year!

15. Energy Savings 15 Annual Energy Usage (kwh)Annual Dollar Amount Spent Currently644,760$74,250.65 With Green Roof 596,403 $68,681.85 Annual Savings 48,357 $5,568.80 The financial savings is based on the fact that the energy used per year in Mullin Commons will decrease by 7.5%

16. Additional Benefits 16 - Green House Gas Absorption - Urban Heat Island Effect - Storm Water Run off - Credits towards Leed Certification

17. Branding & Social Impact Visual representation of Anderson’s commitment to Sustainability – Currently #93 on Aspen Institutes “Beyond Grey Pinstripes” Ranking – Increase Anderson’s appeal to top prospective students, recruiters and donors All with a growing concern for the environment Serve as an example for the external community – First retrofit a green roof at UCLA – One of the first to implement a green roof in LA 17

18. Cost Considerations 18 -Green Roof Installation -Labor -Membrane -Vegetation Modules -Irrigation System Installation -On-going maintenance -Labor -Water

19. Current Strategy Re-Roof: 5 yrs, 25 yrs Total PV Costs: $118,475 Green Roof Strategy Roof today; Re-roof in 40 years Total PV Costs: 133,157 Net Energy Savings: 56,184 Net PV Costs (after savings): 76,974 Net Difference: 41,501 CHEAPER Costs Vs. Benefits *Assumes Conventional Roof = $13 psf; Green Roof = $19-21 psf; Real discount Rate of 3%

20. Feasibility 20

21. Structural Feasibility Structural Feasibility Question?Answer Can the roof support the weight? Can we avoid an earthquake inspection? Is the roof properly waterproofed as is? Sources: Prof. Thomas Sabol of UCLA Civil & Environmental Engineering; Tom Hawkins of LiveRoof; Biltmore Roofing 56 psf Capacity < 73.3% Coverage Concrete & Membrane

22. Fire Regulations Will The Roof Satisfy Fire Regulations?Answer Mitigate Risk of flammable vegetation Maintain appropriate standards for Roof Access for fire fighters Enforce appropriate occupancy level -Appropriate Plants - Irrigation System - Maintain current access - Extensive roof not open to public

36. Total of 56 psf capacity Goal: stay below 10% additional weight to avoid triggering required seismological evaluation. 56 psf * 10% = 5.6 psf. Removal of 6 psf of gravel  total of 11.6 psf across entire roof is maximum Green roof is 16 psf. Thus we can cover 11.6 / 16 = 73% of the roof without triggering the evaluation.
