23. Only university nation wide LEED-NC • 11 certified projects • 2 Gold • 1 Silver • 5 Submitted for Certification • 21 Registered • 32 Registered, Portfolio program LEED-EB Total LEED Projects = 69

24. UF’s Green Gross Square Footage (GSF) • LEED Certified Green GSF: 1.3 million GSF • LEED registered Green GSF: 2.7 million GSF

25. Green Power Avoided emissions of 4,376,814 pounds of CO2 Taking 326 cars off the road Planting 353 acres of mature trees

26. UF’s LEED Experience 10 certified New Construction and Major Renovation Projects

27. UF’s LEED Experience

28. UF’s LEED Experience As of October 2008 UF has over 1,800,000 Gross Square Footage of LEED NC Certified and Registered Projects Space

29. LEED Cost • How much does a LEED building cost more than your traditional building? • What standards are associated with your traditional building? • How much more does LEED cost above code? How Green is/was your last project? • What level of certification are you striving for? • How experienced is your local contractor / design community?

30. Current Soft Cost Data • Estimated soft costs (www.facilitiesnet.com) • People costs v. Energy or Construction costs

31. Current Cost Data • Building costs represent less than 10% of the cost to own/operate building for life of project – 20 year lifecycle. (www.facilitiesnet.com)

32. Cost Literature Review • LEED costs • GSA sites a range of less than 0% for LEED certified to a mean of 2.5% addition to total budget for LEED silver buildings. • UF Facilities Planning and Construction claim $0 additional dollars for a LEED certified building. • Davis Langdon (architect firm) states design firms produce LEED buildings as standard program elements (no additional design fee). • Greg Kats – Average Silver rating for schools (n=33) cost premium = 1.84% • Common perception minimum of 10%

33. Conclusion on First Costs • As UF has gained experience with LEED projects the associated first costs and process has evolved. Major drivers of lowering costs include: • Experience of project team members and local market • Evolution of building standards to include LEED based language • Outcome based selection of credits and levels of certification

34. Review of Annual Construction Performance and Building Savings • 10 certified buildings used in summary reports • Not all buildings achieved credits that are summed in the following slides • Comparisons are based on design estimates. Real data forthcoming this year. UF Annual Saving

43. Commissioning

44. Why Commission? • Complex building systems: • Increased energy efficiency • New technology • IAQ • Reduced environmental impact • ROI • Reporting and accountability • Construction Challenges • Compressed schedules • Training • Labor challenges • Budgets

45. Why Commission? • Chilled water and steam system • Renewable source energy • Heat recovery • Chiller with heat recovery • Demand Control Ventilation (CO2) • M&V • BAS

46. Why Commission? – Life-Cycle Perspective

47. LEED-NC Cx • There are 2 components • EA Prerequisite 1: Fundamental Building • System Commissioning • EA Credit 3: Additional ( Enhanced) Commissioning • District Thermal Energy, Central plant (new since May 2008), EAp1 and EAc3

48. Prerequisite Cx EA3 – Additional Cx Vs. OPR / BOD SD / DD Design Construction Documents Submittals Equipment Arrival Start Up BAS Controls Construction & Acceptance TAB Performance Verification O&M Training Systems Manual Post Occupancy In-Warranty Review

49. Design Review • Cx performs DD, 60% CD & 100% CD reviews • Format used encourages 2-way dialogue • Back-check previous comments • Cx communicate with A/E to review comments and confirm understanding of design

50. O&M/Submittal Review • CxA reviews either prior to or concurrent with AE review • All commissioned equipment reviewed • BAS control drawings reviewed • Cx provide facility staff with a list of key equipment set points
