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 the 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
- 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
- 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
- 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
- Plenum flooring leaves a space between the foundation and the floor to improve air flow and provide more efficient heating and cooling
- The wallboards are constructed using 90% recycled gypsum
- Wall coverings are made from grass, a renewable resource
