3. STEPHEN STIMSON ASSOCIATES LANDSCAPE ARCHITECTS Developing Metrics for Landscape Assessment · LEED – Sustainable Sites · Sustainable Sites Initiative · As designers, once we have applied these principles to design and constructed them, how do we measure their success and actual benefits? · How can these be applied to improve sustainable solutions? · How do we apply them appropriately for each project and site? · Sustainability ENVIRONMENTAL – ECONOMIC – SOCIAL/HUMAN/COMMUNITY · “What do I get out of it?”

22. Developing Metrics for Landscape Assessment · GREENFIELD VS. BROWNFIELD DEVELOPMENT · IFAW 2000 · 5 acres greenfield into conservation · Expanded contiguous open space parcels · Groundwater protection in aquifer protection zone · Protect habitat & biodiversity IFAW 2005 · 5 acres brownfield cleanup & restoration · Cost savings on open brownfield site offset by remediation costs ·

23. BUILDING ENERGY USE · SITE PLANNING AND BUILDING MASSING · BETTER SITE EFFICIENCY AND CIRCULATION · ENABLED PASSIVE SOLAR · INCREASED OPEN SPACE AND HABITAT ·

Other Aspects of Sustainable Design 3.2 Stormwater Management Elements as Landscape Amenities 3.3 Environmental Education 3.5 Contributions to Daylighting Goals and Building Efficiency 3.6 Microclimate and Extending Usability of Exterior Spaces 3.7 Projecting Image and Ethics of Organization 3.8 Attracting potential investors and donors 3.9 Employee productivity, health, satisfaction, retention 3.10 Marketing Opportunities

29. STEPHEN STIMSON ASSOCIATES LANDSCAPE ARCHITECTS Overall Project Achievements · Represent ethics, image and commitment of IFAW · Accommodate site program and support building/ daylighting objectives · Reconnect site visually and spatially to adjacent conservation areas · Improved water quality and protection in aquifer district · Restore open space and provide wildlife habitat · Durable, low maintenance + sustainable native landscape · Promote green development, create local jobs, investment in community

30. STEPHEN STIMSON ASSOCIATES LANDSCAPE ARCHITECTS Metrics of Sustainable Design · Energy Use Reduction in Building Systems · Savings on drainage infrastructure = Investment in Landscape · Improved water quality + increased groundwater recharge · Earthwork: reduced soil export + manufactured soils 6,000CY each · Reduced landscape maintenance and irrigation costs · Reduced energy costs for efficient, low level exterior lighting

37. STEPHEN STIMSON ASSOCIATES LANDSCAPE ARCHITECTS Next Steps and Future Considerations · PLANNING FOR MONITORING AND ASSESSMENT IN FUTURE PROJECTS · DEVELOP EMPIRICAL RESULTS · INCORPORATE MEASUREMENT IN DESIGN PHASE · INCLUDE FEES FOR MEASUREMENT IN POST-CONSTRUCTION SERVICES · CONSIDER PRO-BONO SERVICES FOR MONITORING · EXPLORE RESEARCH GRANTS AND/OR ENGAGE INSITUTIONS/UNIVERSITIES
