Future Enhancements

Environmental Learning Center

Thoughtfully designed to foster collaboration, catalyze innovative ideas, and support efficient administration of our educational programs, the Environmental Learning Center at Drumlin Farm will be an educational model of energy-saving features and green building design, sized to fit strategic plans for growth within a modest budget. 

Green features will include:

  • Net Zero Energy – Rooftop photovoltaic panels will generate enough energy to power the entire building as well as two barns and a wildlife enclosure
  • Highly efficient electric heating/cooling
  • Visible stormwater management in rainwater gardens
  • Native plantings to attract wildlife, and removal of invasives species around current site
  • Triple glazed dual low-e windows throughout
  • Daylighting with window blinds to direct light
  • Low/No VOC products used throughout; no products with added formaldehyde
  • Super-insulated building envelope, verified through depressurized/pressurized theatrical fog testing and infrared scanning
  • Sustainable materials, locally sourced when possible
