3 Business Goal: create marketable profitable product

4 Business Goal: create marketable profitable product Global Climate Goal: limit global temperature increase by cutting GHG emissions to 80% below 1990 levels

5 Business Goal: create marketable profitable product using LEED-ND to create better product & capture market share Global Climate Goal: limit global temperature increase by cutting GHG emissions to 80% below 1990 levels using LEED-ND to reduce carbon footprint

6 How land development is done has great leverage on LEED certification and climate change Regional location 25-65% reduction Mixed use and density up to 50% Site design 4-18% reduction

7 In California AB 32 Caps & rolls back California GHG Blueprint California Regional Plans include energy modeling or no $ SB 375 et al City & County plan modeling to include GHG emissions Executive Order S-3-05 GHG 80% below 1990 levels by 2050 Pending legislation linking land use, transportation, $ LCFS- reduced carbon in motor fuels State sued San Bernardino County to force energy considerations in its plans

8 In Massachusetts New Massachusetts policy requires developers to: mitigate greenhouse gas emissions from projects. consider commuting effects on carbon footprint.

9 LEED-ND & Carbon--Parallel Goals

10 Carbon Footprinting Baseline Green Buildings Neighborhood Infill Mixed Use Neighborhood Infill Site Design 000 s tons CO2/year Zero Carbon Certified Silver Gold Platinum LEED- ND The LEED-Carbon Curve

11 Development/Environment Techniques

12 Very tough Platinum Difficult Gold Silver Easier to moderate Certified Prerequisites LEED-ND Ladder

13 External Transportation Internal Circulation Landscape & Open Space Building & Energy Usage Utilities & Infrastructure CO2 Baseline CO2 Budget GHG Generation Carbon-Neutral Renewables, Sequestering, Offsets A Carbon Model

14 Transportation External Transportation LEED-NC LEED-EB 2030 Building Usage Internal Circulation Landscape & Open Space LEED- ND Civil Utilities & Infrastructure Sustainable Sites Initiative LEED- ND Making the Model Real

15 LEED-ND Smart Location & Linkage Project Location: Brownfield, utilities, infrastructure, schools, wetlands, surrounding development, infill or greenfield affects modal choice, trip length, VMT can convert to mtco2

17 LEED-ND Neighborhood Pattern & Design Urban Design: Compact development, walkability, access to open space and public facilities, street network, housing types density (energy), VMT reduction, trips avoided, pedestrian opportunities

18 Mixed Uses

28 Baseline Carbon Model Greenfield 200 acres Single use office park at.3 FAR Buildings built to code No renewables Buildings: 27,330 Tons CO2 Trips: Total: 47,470 Tons CO2 74,800 Tons CO2

29 Site Design Street Connectivity Ped Walks & Open Space Transit Proximity Buildings: 27,300 Tons CO2 Trips: 42,720 Tons CO2 Total: 70,020 Tons CO2

30 Mixed Uses: Same 200 acres of office mix with retail & residential More trips internalized change to walking Reduces peaking better use of access road capacity Buildings: 27,330 Tons CO2 Trips: Total: 40,350 Tons CO2 67,680 Tons CO2

31 Green Buildings Phased reductions in energy Initial 50% reduction based on code equivalents Buildings: 8,200 Tons CO2 Trips: Total: 47,470 Tons CO2 55,670 Tons CO2

32 Neighborhood Infill : Mixed uses fill in around office Shorter trips to adjacent uses Shared parking still works Add transit access Buildings: 27,330 Tons CO2 Trips: Total: 22,780 Tons CO2 50,110 Tons CO2

33 Combined Techniques Mixed Use 2030 Challenge Neighborhood Infill Site Design Buildings: 8,200 Tons CO2 Trips: Total: 18,160 Tons CO2 26,360 Tons CO2

34 Zero Carbon Development Zero Energy Buildings PV on Parking & Building Roofs Reduce Program Aggressive TMA & Site-Wide Buildings: 0 Tons CO2 Trips: 18,160 Tons CO2 Other: (18,200)Tons CO2 Total: 0 Tons CO2

35 LEED-ND has benefits beyond the rating system Set goals with your team Create a model to realize your goal Be clear about how to measure progress Keep learning everyone else is Persist!
