Sustainability and Leadership in Energy and Environmental Design (LEED) Lessons Learned from The Fernald Preserve Visitors Center

slide2
LEED Lessons Learned The Fernald Preserve Visitors Center

Background

  • The Fernald Preserve is a former uranium manufacturing facility remediated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
  • During the decision-making process related to future land use, the U.S. Department of Energy (DOE) and the community agreed to an undeveloped park with an emphasis on wildlife
  • DOE committed to establishing a visitors center to fulfill an informational andeducational function within the community

Background – Why Green?

  • Executive Orders 13123, Greening the Government Through Efficient Energy Management, and 13423, Strengthening Federal Environmental, Energy, and Transportation Managementrelated to energy efficiency and environmental stewardship
  • Alignment with DOE Orders and DOE Strategic Goals related to energy efficiency and sustainable practices
  • Alignment with the purpose of the Fernald Preserve and its mission

Background – What Is Green?

  • A green building incorporates sustainable design principles to reduce or minimize the impact to the environment and reduce energy and water consumption
  • Sustainable design seeks to reduce negative impacts on the environment and the health and comfort of building occupants. The basic objectives are to reduce consumption of nonrenewable resources and minimize waste while creating a healthy and productive environment.

Materials and Resources

  • 75 percent of waste was recycled or salvaged
  • 23 percent of construction costs were for
  • recycled materials
  • 43 percent of material costs were for items sourced within 500 miles
  • 51 percent of wood-based materials were made of recycled content
  • Rapidly renewable materials were used
  • Paper, cardboard, metal, plastic, and glass
  • are recycled
slide13

Indoor Environmental Quality

  • Natural light and views of the outdoors
  • No odorous or irritating building materials
  • Heat-producing rooms are ventilated
  • Reduced indoor chemicals and pollutants
  • Occupancy sensors control lighting
slide14

Innovation and Design

  • Summer solstice
  • Green cleaning program
  • Biowetland wastewater system
  • Education outreach
  • Oversight by aLEED Accredited Professional during construction
slide15

Lessons Learned

  • Quality control checks by three people resulted in receiving the majority of the credits
  • Quality of documentation and service from low-tier subcontractors was problematic
  • Instances of lacking specific engineering disciplines necessary to secure LEED credit
  • Certification costs were high
slide16

Lessons Learned

  • Facilities management staff must be a part of the commissioning team from the outset
  • Maintenance contracts may be appropriate initially for specialized equipment or operations
  • Experiencing approximately a 36 percent reduction in electric usage compared to conventional building construction
  • Experiencing approximately a 30 percent reduction in water usage compared to design basis
