11. Green InfrastructureLand Acquisition 2001 - 2008 • Citizen Approved Sales Tax 8 out of the Past 10 Years for Conservation Land • Sales Tax Generated $75M to Date • Leveraged Those Funds with Regional and State Dollars to Buy $450M worth of Land • 85,000 Acres Overall and 45,000 Acres Lands Necessary for CERP

12. Green InfrastructureMartin County Public Lands

13. Green Infrastructure Water Quality • Completed 14 Local Water Quality Retrofits • Leveraged $15M of Local Funds with State and Regional Grants to Construct $31M of Local Projects serving 4,500 acres

14. Green Building • A whole building systems approach to design, construction and operation that results in: • Minimizing environmental impacts (Environmental) • Reducing energy consumption (Environmental/Economic) • Improving building environment for occupants (Social)

15. Florida Statute 255.2575 • All county buildings shall be constructed to meet the United States Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) rating system, the Green Building Initiative's Green Globes rating system, the Florida Green Building Coalition standards, or a nationally recognized, high-performance green building rating system as approved by the Department of Management Services. • This section shall apply to all buildings the architectural plans of which are commenced after July 1, 2008.

16. Sustainable Building • Sustainable building integrates building materials and methods that promote environmental quality, economic vitality, and social benefit through the design, construction and operation of the built environment. • Sustainable building design encompasses the following broad topics: efficient management of energy and water resources, management of material resources and waste, protection of environmental quality, protection of health and indoor environmental quality, reinforcement of natural systems, and the integration of the design approach.

17. Not As Green As It Looks On average LEED buildings are 25-30% more efficient---USGBC Publicized Claim Based on 552 Certified Buildings “LEED buildings whose owners participated in the study reported their energy data used an average of 29% more energy than the most similar buildings in the dataset of the study the authors chose to use as a comparison”!---Henry Gifford “Chasing green points doesn’t get you good buildings that are truly green. You can get a LEED rating and not save any energy compared to traditional buildings”.--- Joseph Lstiburek

18. Green Building How to be Green • Use less glass • Don’t over-ventilate • Build a tight enclosure • Insulate on the outside • Duct air conditioning supply and return • Demonstrate measured energy savings • Pressurize the building Fashionable but NOT Green • Under floor supply plenums • Double facades • Passive ventilation • Green roofs --- Joseph Lstiburek

19. Green Building • Lessons learned from Courthouse Event: • Materials • Building Envelope • Air Conditioning Control

20. FY09 County Projected Electricity Use $6.7 Million in FY09 Budget

21. Energy Conservation During the FY09 budget hearings the Board of County Commissioners directed an energy reduction target of 10% for Martin County electricity and fuel usage during 2009.

22. Energy Conservation Beginning in 2007 • FPL Performance Contract – Holt Correctional Facilities • Initial Cost = $2.6 M Total Savings = $3.2M • Net Positive Cash Flow = $372K • Annual Electricity Savings = 2.9 M kWh • Annual Water Savings = 7.3 MGal

23. Energy Conservation Beginning in 2009 • Trane Performance Contract – Courthouse Complex plus 27 County Facilities • Initial Cost = $4.86 M Total Savings = $10.2M • Net Positive Cash Flow = $1.7M • Annual Electricity Savings = 3.5 M kWh

24. Energy Conservation Electricity Reduction 11% Reduction in 2009 19% Cumulative Reduction Since FY07

25. Potential Energy Conservation BCC Directed Target • Proposed Parks Lighting Retrofit – Musco • Utilities Operation Energy Conservation Audit – CDM Engineering

26. FY09 Projected Fuel Usage $1.3 Million in FY09 Budget Represents 90% of Usage BCC Only

27. Fuel Reduction • Increase number of hybrid vehicles in fleet • Greatly reduced use of take home vehicles • Encourage departments to plan trips more efficiently (i.e. carpooling to meetings) • Computerized fuel tracking system to identify vehicles that are not meeting individual mileage expectations • Replace older vehicles with more fuel efficient vehicles as part of replacement cycle; hybrids when it benefits the County • Working on employee training program to improve driving habits • Need to focus on high use operations

28. Life Cycle Costing “It’s not easy being Green and it initially costs more” Cost savings occur over the Life Cycle of the Asset

29. Life Cycle Cost Analysis Life cycle cost analysis includes the costs of planning, design, construction, operation, maintenance and disposal of a facility over the useful life of the facility using Net Present Value Analysis. Both the FP&L and Trane performance contracts demonstrate the value of Life Cycle Cost analysis.

30. Existing Regulation FS 255.2575 – County construction to meet Florida Green Building Coalition Standards FS 163.04 – An ordinance, deed restriction, covenant, declaration or similar binding agreement may not prohibit or have the effect of prohibiting solar collectors, clotheslines, or other energy devices based on renewable resources from being installed.

31. Sample Regulation • Require signs and billboards to use renewable energy sources and LED,s • Differential fees for projects meeting sustainability goals • Include orientation criteria in LDR’s • Include energy performance in LDR’s • Require moisture sensors in irrigation systems • Permit vegetable gardens and composting • Include cool roofs and radiant barriers in LDR’s

32. Summary of What We Are DoingOverall Of 135 best practices identified in the “Sustainability Best Practices” matrix Martin County is currently doing 91 of them or 67%. Staff is investigating the remaining 44 BMP’s for applicability and cost effectiveness. 14 of remaining 44 BMP’s are policy issues that will need Board action. Staff will continue to seek to identify additional Sustainability BMP’s and bring policy issues to the Board.

38. Sustainability Moving Forward • Need to ensure that we are current • Plastic versus paper bag conundrum • Wisdom of recycling

39. RecommendationsCurrent • Recommend a contract “green/energy conservation coordinator” to be focal point of our efforts towards sustainability. • Recommend a policy that sustainability/green projects be required to have a net positive life cycle cost to be considered in FY10. • Recommend that our overall strategy be: first practice conservation; second to improve building envelopes/mechanical equipment; and third to invest in renewable energy.

40. RecommendationsFuture • Countywide Energy Conservation Policy • Procurement Policy • Building Use / After Hours • Countywide Building Recycling Efforts • Green Building Guidance for Private Sector • Consider an Energy Element For the Comprehensive Plan
