Design Competition Guidelines (Continued)

Design Criteria

  • The center must be self-sustaining, meeting all energy, water and waste treatment requirements form on-site resources.
  • The technologies providing for these functions must be integrated into a building and site design with high aesthetic values consistent and compatible with the historic setting of the area.
  • The center must visibly demonstrate self-sustaining technologies either through intrinsic design or through educational displays.
  • Entries will also be evaluated based upon projected life-cycle costs of the conceptual design.
  • The welcome center component of the building shall be based upon 1200 net square footage.
  • The water supply and waste treatment systems shall be designed to meet the following projected visitor usage:
    • Initial usage upon opening
      1. Average Daily Usage 1300


      Peak Daily Usage 2300
      3. Average Hourly Usage 145
      4. Peak Hourly Usage 575
    • Design Year Usage (2020)
      1. Average Daily Usage 2100
      2. Peak Daily Usage 3750
      3. Average Hourly Usage 235
      4. Peak Hourly Usage 925

      NOTE: It is assumed that the facility will be open only during the hours of 8 a.m. to 6 p.m.

The design should address the approach used to meet the initial and future demand. If the concept is based upon adding additional components to meet future demand this shall be discussed, including the number of components and the cost.

  • The building shall include sufficient square footage to house rest room and waste treatment technology to serve these visitor projections.
  • Seasonal temperature, humidity and wind data, precipitation averages and extremes should be based on data available from the National Oceanic and Atmospheric Association (NOAA). For purposes of comparison, all teams shall use the TMY2 Meteorological Data for Sterling VA (Dulles Airport) as the basis for their performance projections/simulations. We recommend use of version 1.6 of the Energy-10 program that was developed by the Department of Energy's National Renewable Energy Laboratory (NREL) in conjunction with the Sustainable Building Industry Council (SBIC), which incorporates this database. Other software may be used for such calculations, but, again, for purposes of comparison, presentation of results must be in comparable formats (discrepancies, if results are obtained with other software, must be noted and explained if possible). Version 1.6 Energy-10 software can be obtained through SBIC:

    Final determination of specific information to be included and formats for the presentation of performance projections will be announced in the near future.

  • All designs must comply with the Americans with Disabilities Act Accessibility Guidelines.
  • All designs must comply with the following building, electrical and mechanical codes.
    • 2000 International Building Code (IBC)
    • 2002 National Electrical Code
    • 2000 International Plumbing Code
    • 2000 International Mechanical Code
    • 2000 National Fire Protection Association (NFPA) Fire Prevention Code
  • All competitors will be required to visit the site and incorporate relevant information in the formation of their submission.
  • All submissions must address applicable local regulations regarding water supply/treatment and waste water treatment with fail safe contingency strategies specified. A workshop is being planned on the relevant technologies and corresponding regulatory issues. Representative of each team are required to attend the workshop, which will also be open to the public.
  • While at this time construction funding is not available, the initial estimate is $750,000 for the construction of the facility. It is intended that a significant percentage of the technology utilized at the facility will be donated to the project. The estimates developed by the entrants should focus on the cost of the building and associated site improvements necessary to the successful implementation of their concept. Each entry shall detail the specific manufacturer technology upon which the concept is based.
  • The intent is that each design concept shall be based upon meeting 100% of the demand. Entrants should address how they would propose to address extremes in terms of temperature, prolonged sunless days, prolonged drought, etc.
