1. Fighting Fire with Fire: Fort Bragg Goes Platinum with a new LEED Fire Station Kim M. Fowler Senior Research Engineer Sustainable Design and Development Energy and Environment Directorate Pacific Northwest National Laboratory 1

2. Technical approach: compare the performance of a new Combined Emergency Services Station designed using whole building design approach to an FY02 Fire Station designed using a more typical design approach. 35% design drawing of CESSPhoto of existing station Fort Bragg Fire Station

4. Cost neutral LEED Platinum 50% energy reduction 30% domestic water reduction 50% wastewater reduction 25% decrease in operational costs LEED for New Construction Certified26-32 Silver33-38 Gold39-51 Platinum52-69 Design Goals

5. Integrated Design Charrette held May 2008 35% design LEED Platinum - 57 points 42% modeled energy savings over theoretical baseline Cost estimate $18k over budget (0.6%) 4 Iterations of Design April – September LEED Platinum – 55 points 38% modeled energy savings Cost estimate $100k over budget (3.5%) Cost is fixed Construction contract placed Cost Neutral

6. The Team Pre-Charrette Charrette During Design Construction Whole Building Design

7. Each team member had a stake in the project achieving the goals Experienced team members with a diverse set of skills The Team

8. Energy modeling, early and often to inform design options Preliminary LEED scorecard done based on 1391 LEED Credit Strategies Specific for the CESS Fire Station, included Summary of LEED requirements Multiple option descriptions Costs estimates Advantages & Disadvantages Contacts & 3 vendors References Given to the project team early and discussed on multiple conference calls Pre-Charrette

9. Re-state project goals Use Pre-Charrette research for “new” and/or innovative technologies to address potential technical questions Use real-time energy modeling as a tool to discuss options Don't be too tied to any specific design strategy Have real-time cost estimates Use sustainable design experts from various technical fields For LEED certification, the A/E must do the LEED design credit templates and the builders must do the construction credits Charrette

10. Iterative Design Reviews Time needed for quality, expert design review Load calculation optimization tools needed to size mechanical equipment appropriately Design specification language needed to target “sustainable” features Commitment to high performance design goals including achieving LEED Platinum certification Commitment to LEED Platinum LEED Accredited Professionals part of team pre-charrette through construction and operations LEED technical assistance available throughout process LEED points protected during Value Engineering and design reviews During Design
