Generating Renewable Energy

  • Photovoltaic arrays (42.84 kW on Environmental Learning Center roof, 7.9 kW on Nature Center roof, 10.3 kW on Sheep & Goat Barn roof, and 15.6 kW on Green Barn roof) installed

Building Green Buildings

  • Environmental Learning Center
    • Net Positive Energy through a 42.84 kW rooftop photovoltaic array that will annually generate more energy than the building consumes
    • Southern exposure to maximize solar access for 119 rooftop panels
    • Super-insulated and airtight building envelope with triple glazed windows
    • Highly efficient electric heating/cooling (no fossil fuel use)
    • Energy recovery ventilation system to reduce the energy required to heat/cool fresh air entering the building
    • LED lighting throughout the building, with occupancy sensors and daylight sensors to minimize electricity for lighting
    • Rain gardens for stormwater management
    • Sustainable finish materials and all low/no VOC products used wherever possible
    • Work stations located for access to views and operable windows
    • Living Building Challenge New Zero Energy certification anticipated
  • Poultry House
    • Day-lighting
    • Passive ventilation design
    • Re-use of existing structure
    • Recycled rubber roof
    • Poultry Pond deck and ramp made from wood fiber and recycled plastic
  • Farm Life Center
