High Performance Home Designs
    for Greensburg, Kansas
             Dr. Ren Anderson
          NREL Residential Research
Goal: Cost Effective, Production-Ready
          Design Packages

  • High Performance
    Envelope
  • High Performance
    Equipment
  • Cost Effective Integration
  • “Bombproof” Reliability
Market Transformation Challenges
Level 1- Meets Minimum Residential Performance Requirements:
Technology meets minimum availability, reliability, O&M and durability
requirements and provides high potential value to builders, contractors, and
homeowners.




Level 2- Can Be Integrated with the Residential Construction
Process:
Best practice design details and construction sequencing are known and accepted
by builders, contractors, and local code officials. Costs and benefits have been
validated based on construction of one or more pilot homes.




Level 3- Can Be Built on a Production Basis:
Quality assurance requirements, quality control requirements, and training
requirements are understood and individual responsibilities are accepted by
suppliers, builders and subcontractors.

   Goals
   • Reduce dependence on traditional fossil fuels
      Example initiatives
      – Charging stations for electric vehicles
      – Centralized bio-diesel storage tank
      – Encourage telecommuting and walking
   • Reduce Greensburg’s carbon footprint
      Example initiatives
      – Encourage availability of alternative fuels
      – Encourage walking, biking and ridesharing

Key Success Factors Studied by
            NREL

            Interest and
            Commitment

Short Term Challenge for Greensburg



       Houses and businesses
                  or
       “green” transportation?
          Longer Term Challenges
• Predicting future vehicle population and alternative
  fuel/ technology availability locally
• Covering the cost of replacing current or lost vehicles
  with alternative-fueled vehicles
• Limited local maintenance and service support for
  AFVs and advanced technologies
• Ensuring the availability of alternative fuels at
  competitive prices
• Developing the infrastructure required for alternative
  fuels and advanced vehicles with limited vehicle
  population.
     Data Provided by Stakeholders
       Most of the data available was pre-storm

Vehicle Population (within 30 miles)
   – Approximately 4,000 total licensed vehicles- 100 FFVs, 300
     diesel, 3,600 gasoline. (Donated- Honda GX, Ford Escape
     FFV Hybrid, GM Hybrids)

Annual Fuel Usage (incomplete data)
   – Approximately 1.6 million gallons gasoline, 415,000 gallons
     diesel

Fueling Locations
   – Kwik Shop, Southern Plains Co-op (includes propane), Volz
     Oil, Kansas Dept. of Transportation (B5), Kiowa County, City
     of Greensburg (donated CNG refueling station)
      Options Considered in Analysis


•   Biodiesel (B5, B20)
•   Ethanol (E85, E10)
•   CNG and LNG
•   Propane
•   Electricity
•   Hybrids
•   Idle Reduction


               There is no silver bullet
           NREL’s Recommendations
• Get commitments from anchor fleets to use alternative
  fuels and advanced technologies
• Implement a purchasing policy for the City of Greensburg
  and Kiowa County that requires purchase of alternative
  fuel and advanced-technology vehicles
• Hold educational events to provide a forum for fleets and
  the public.
• Explore the availability of CNG and propane vehicles and
  options for refueling multiple vehicles at the donated CNG
  refueling station.
• Complete the business case for adding a neighborhood
  electric vehicle dealership in Greensburg.
    NREL’s Recommendations Continued
•   Purchase neighborhood electric vehicles for use in the
    city (i.e. building inspectors and meter readers)
•   Study E85 and biodiesel pricing structures from current
    suppliers. Determine local pricing strategies and their
    potential impact on the success of alternative fuels.
•   Continue to pursue alternative fuel supply options and
    contracts with local biofuel producers.
•   Explore options for adding a hybrid dealership in
    Greensburg
•   Solicit grants or donations to cover the initial cost of
    upgrading the existing fueling infrastructure
   Potential Economic Development
             Opportunities
• Providing sales and services for electric vehicles
• Building an infrastructure for biodiesel
• Building an infrastructure for E85
• Providing maintenance and other support for CNG and
  Propane-fueled vehicles
• Providing sales, services, and support for hybrid electric
  vehicles
• Providing sales, installation, and other services for idle-
  reduction technologies
• Biofuels production facilities

              Conclusions
• Imperative to persistently educate
  agencies and individuals on life cycle
  cost of energy in buildings
  – Efficiency first, then renewables
• Consider wind and solar; cost varies
  tremendously depending on resource
  and incentives
• They have fully embraced and learned
  to use “Green” as an economic
  development tool
              Conclusions
• Cultural change, on DOE’s timescale, would
  have been impossible without Discovery
  Channel, BNIM, USGBC influences
• Financing assistance (information and/or
  cash) is as important as technical assistance
• Disaster recovery is a very difficult
  environment to influence

• BUT- If it can be done
  in Greensburg…
