LEED Certification

U.S. Green Building Council Logo

The library was awarded a silver LEED (Leadership in Energy and Environmental Design) certification in from the U.S. Green Building Council in 2009 and was theĀ first public building in Delta Township to qualify as a LEED certified building.

LEED certification focuses on three main components:

  • Environmental benefits – using recycled materials and increasing energy efficiency conserves resources
  • Economic benefits – using local resources and suppliers reduces carbon footprint of project, but also stimulates regional economy
  • Health/Community benefits – users enjoy a building with high air quality committed to preserving its surrounding environment.

Green Aspects of DTDL


  • Parking lot lights
    • energy efficient, designed to preserve dark sky and limit light pollution
  • Landscaping
    • drought-resistant, slow-growing ground cover and shrubbery require less watering and maintenance by gas-powered equipment.
    • rain gardens to absorb parking lot runoff and help filter out pollutants
  • Footprint
    • a high ratio of free soil (unpaved) remains surrounding the building and parking lot in order to improve storm water runoff
  • Bike racks, alternative vehicle parking and sidewalks
    • promotes alternative forms of transportation to and from the library by providing preferred bike and alternative fuel vehicle parking spaces and convenient bus stop and pedestrian access


  • Building materials
    • 35% of the steel used in the building skeleton is recycled
    • concrete used in the building uses 50% recycled fly ash from a local source
    • tiles used throughout the building are made from recycled glass
    • volatile organic compounds (VOCs), usually found in adhesives, paint, stains and glue were limited as much as possible
  • Windows
    • maximizing the available natural light reduces the amount and strength of artificial light required
    • glazing on the windows filters harmful UV rays and restricts loss of heat
    • the view facing the woods helps to highlight our natural setting
    • clerestory windows with moisture sensors open and close to increase air flow
  • Flooring
    • Plenum flooring leaves a space between the foundation and the floor to improve air flow and provide more efficient heating and cooling
  • Walls
    • The wallboards are constructed using 90% recycled gypsum
    • Wall coverings are made from grass, a renewable resource
