Sustainable features

  • Demolition and construction waste was recycled.
  • The building's 218-foot-long south wall maximizes solar heat gain in winter and natural lighting year-round.
  • 100-kilowatt rooftop array of solar panels provides upwards of 24 percent of the building's electricity.
  • Four panels of evacuated tubes filled with glycol on the south-facing wall provide the building with hot water.
  • Geothermal energy system pulls 55-degree water from four quarter-mile-deep wells in Sachem's Wood.
  • The building's narrow envelope (57 feet wide) allows for the penetration of natural light into interior spaces.
  • Interior lighting responds to occupancy levels and outdoor light. Lights automatically turn off after several minutes in unoccupied spaces, and fluctuate in intensity depending on the amount of ambient light.
  • Manually operable windows encourage natural ventilation
  • Green construction materials including “thermally inactive” concrete and low-E glass and insulation, waterless urinals and low-impact paint.
  • Recycled, recyclable, sustainably harvested or manufactured nontoxic materials.
  • Half of the interior red oak paneling was harvested from Yale-Myers Forest. Wood certified by Forest Stewardship Council.
  • Briar Hill sandstone used in façade was quarried within 500 miles of campus
  • Rainwater harvesting system and cleansing pond
