What is LEED? LEED-NC: LEED for New Construction and Major Renovations/Additions LEED-EB: LEED for Existing Buildings LEED-CI: LEED for Commercial Interiors LEED-CS: LEED for Core and Shell LEED-H: LEED for Homes LEED-NC: LEED for Neighborhood Developments (public release: 2006)

What is LEED? • Structured System to Measure Green Building and Track Progress • Five Major Categories for Achieving LEED Points • Sustainable Sites • Water Efficiency • Energy and Atmosphere • Materials and Resources • Indoor Environmental Quality • Innovation in Design

What is LEED? 289 Certified Projects 2,069 Registered Projects • 235 M gsf • 50 States • 13 Countries

What is LEED? • 69 Available Points • Four Categories of Certification: • Certified: 26-32 Points • Silver: 33-38 Points • Gold: 39-52 Points • Platinum: 53-69 Points

Establishing Goals and Priorities “Good Practice” Low or no cost Known, reliable, readily available Owner/programmatic requirement Can be implemented in almost any design Design Integration Influence overall design approach High degree of integration and/or analysis Innovative Strategies (Cost implications) Depend on Budget/Funding opportunities

Section 1: Sustainable Sites

Sustainable Sites Good Practice Erosion/Sedimentation Control Plan Bicycle Racks and Shower Facilities Reflective, high-emissivity roofing Light-colored exterior paving (Heat Island) Growth near public transportation Alternative transportation parking, vans and hybrids

Sustainable Sites Design Integration Native, adapted plantings for landscaping On-site infiltration of stormwater runoff (coordinated with water efficiency category) Exterior lighting design to minimize light pollution

Sustainable Sites Innovative Strategies On-site collection and reuse of stormwater (coordinated with water efficiency category) Vegetated Roof System for reduced stormwater runoff, reduced Heat Island effect

WPI LEED Scorecard 8 Achievable Sustainable Site Points Identified 14 Possible

Section 2: Water Efficiency

Water Efficiency Good Practice 0.5 gpm lavatory faucets, automatic shutoff 2.0 gpm (or less) for showerheads Water-efficient fixture options for toilets and urinals (e.g., 0.5 gpf urinals, waterless urinals, dual-flush toilets)

Water Efficiency Design Integration On-site collection and reuse of Stormwater and/or steam condensate. Potential Uses: Toilet/Urinal Flushing Landscape irrigation – none proposed

WPI LEED Scorecard 4 Achievable Water Efficiency Points Identified 5 Possible

Section 3: Energy and Atmosphere

Energy and Atmosphere Good Practice Prescriptive criteria for building envelope, lighting, motors, etc. Additional Building Systems Commissioning HCFC Refrigerants and Halons prohibited Measurement & Verification

Energy and Atmosphere Design Integration Building orientation, massing, glazing distribution Reduce regulated energy costs by 20%+ versus ASHRAE 90.1-2004. Evaluate via energy modeling. Perimeter/public space dimming strategies (coordinated with IEQ) Natural Ventilation opportunities (coordinated with IEQ)

Energy and Atmosphere Innovative Strategies Ground Source Heat Rejection for Cooling Equipment Efficiencies Renewable Energy Systems Green Power Purchasing
