6 Traditional Neighborhood Design Town Center 5-minute walk to most everyday activities Street network forms a continuous web with high inter-connectivity Small, pedestrian-friendly streets Mixed uses and architectural styles throughout Civic and community sites: identity Douglas Farr. 2008. Sustainable Urbanism. Duaney, Plater-Zyberk. 2001

7 Green Buildings Community Visioning Creates Focus Air Quality/Greenhouse Gas Reduction Provide Clear Data Assess traffic patterns, energy usage, common practices Review local ordinances relating to air quality Establish objectives Reduce vehicular traffic Reduce greenhouse gases Promote green building Promote green rehabilitation for residences and businesses Community Planning

8 Average Savings of Green Buildings ENERGY SAVINGS 30% CARBON SAVINGS 35% WATER USE SAVINGS 30-50% WASTE COST SAVINGS 50-90% Benefits of Green Building

10 Green Building Framework for Overall Quality Improvements Green Building Links: Air Quality Lower Energy Consumption Greenhouse Gas Reduction Water Quality Reductions in Solid Waste Improved Economic Returns Improved Human Health Outcomes Better Neighborhood Design

11 NJ Green Building Manual Authorized in 2007 (C.52:27D-130.6): Guidance and consistent performance criteria Owners, builders, and construction professionals Programs that encourage/require green building Resource for local governments and private sector Residential and commercial buildings

12 Foundations for GB Manual Performance Based Tiered Point-Based System Web-based Tool Performance Metrics Integrated System Implementation Reporting & Verification

13 GB Manual Development Tiered Performance Metrics & Targets Green Building Strategies Organization/Content Env. Impacts Evaluation Protocol Cost Impacts Technical Guidance & Resources: Case Studies Calculation Tools Illustrations/Diagrams Impact Areas: Five green building categories Methodology: Eco-Efficiency Cumulative Impacts Administration: Verification & Documentation Implementation Recommendations Ongoing Performance Evaluation: Evolution of Guidelines Stakeholder Process

14 - FIRST COST - OPERATION COST (Energy, Maintenance, Remodeling) + HEALTH OF EMPLOYEES + COMFORT + PRODUCTIVITY + ENVIRONMENT Design… Build… Operate… Evaluate

15 Commercial Building Process Points of Leverage: 1.Incentives Expedited Permitting/Permit Assistance Awards/Publicity 2.Verification/Documentation for getting incentives require: Integrated Design Meeting Performance Target Checklist/Management Plan Pre-Design Programming Resources: Best Practice Strategies Case Study Examples Integrated Design Tools

16 Commercial Building Process Commercial Building Process Points of Leverage: 1.Incentives Expedited Permitting/Permit Assistance Technical Assistance Awards/Publicity 2.Verification/Documentation for getting incentives Require Schematic Drawings/ASHRAE EQ (As Designed) modeling to show how design helps project meet performance targets Schematic Design Resources: Best Practice Strategies Case Study Examples Integrated Design Tools

17 Strategy Impacts Center for Green Building Remodeling Strategies Impact Lenses Description of Strategy & Recommended Approaches Energy Efficiency/ CO2 Reduction (high, medium, low) Water Conservation & Management (high, medium, low) Indoor Air Quality (high, medium, low) Resource Conservation (high, medium, low) Cost (high, medium, low) Difficulty Level (high, medium, low) EXAMPLES A.Complete home energy performance audit EA48 B. Test for and install a radon mitigation system if required IEQ163 HLHL LLLL L H-if mitigation required LL depends on course of action L H- need experts to assess!

18 Energy Use Intensity (EUI) of LEED and national building stock Post-Occupancy Evaluation

19 Greening NJs Existing Housing Stock Greening NJs Existing Housing Stock 54% of census tracts building stock with a majority of single family detached units 20% attached/2/3/4 units

20 Green Remodeling Air Quality

21 Why green building? On average, Americans spend 90% of their time indoors, yet the air inside buildings can be 5-10 times more polluted than outdoor air, according to the U.S. Environmental Protection Agency. Most common pollutants are: Radon Combustion products Molds, pet dander, pollen VOCs Lead dust and asbestos Source: http://www.epa.gov/iaq/greenbuilding/index.html Indoor Air Quality

22 NJ Green Home Remodeling Sample Strategy Write-up

23 Weatherization & Energy Cost Impact $ $$$$ Low High Weather-strip Doors and Windows (WC, EE) Install Programmable Thermostats (EE) Provide Proper Moisture Management Strategies (WC, IAQ) Select high efficiency HVAC equipment (EE) Insulate Hot Water Heater & Pipes (EE) Install attic insulation (EE) Consider a Photovoltaic System (EE) Consider solar water heating (EE) Conduct a home performance audit (EE)

24 BUILDING DESIGN Energy Efficiency - Strategies Building Orientation Green Roofs Moisture Control Advanced Framing Building Envelope Air sealing Insulation Performance Glazing
