Environmental Indicators

BTUs Consumed Per Year / Square Foot
  • Overall energy use per square foot increased by 7.8% in 2014 due primarily to an increase in thermal use attributable to a 5% increase in heating degree days from 2013 to 2014.
  • Electrical use per square foot decreased by 2.5%.
  • Energy projects in 2014 included lighting retrofits, including LED lighting, continued installation of occupancy sensors, installation of high efficiency hot water heater and boilers, steam trap repair, and mechanical equipment insulation.
MHC Annual Greenhouse Gas Emissions
  • Greenhouse Gas (GHG) emissions are 3.3 % higher than 2013 levels, attributable to the causes described above for energy use increase.
  • GHG emissions are 2.4% below 1990 emission levels, our goal for 2020 is 10% below 1990 levels.
  • Since neither fuel choice nor degree days can be relied upon to maintain or reduce emission levels, work remains to reduce emissions through reduction in campus energy use.
Recycled Materials
  • Recycling as a percentage of total discards remains above 50%, with 2014 at 55%.
  • Routine trash disposal is 15% below 2006 levels with recycled materials as a percentage of discarded materials increasing 15% over the same period.
  • Not included in these numbers are construction debris, which are recycled, and Equestrian Center waste, which is composted. Both are excluded because their volume would mask variability of other discards.
Developed Campus Area Storm Water Management
  • Capturing and treating storm water to remove sediments is an important component of maintaining and restoring the health of Upper and Lower Lakes and Stony Brook.
  • Prior to 2001, we did not treat any captured storm water. Treatment structures are installed during major construction.
  • The percentages remain unchanged from 2013 as no projects afforded the opportunity to redirect more drains to treatment structures.
Contiguous Campus Land
  • This indicator reflects the percentage of the 714 acre contiguous campus that has impervious surfaces. The percentage remains unchanged from 2013.
  • Impervious surfaces include all campus buildings and surrounding terraces, roads, sidewalks, and parking lots.
Dining Services % of Sustainable Purchases
  • Sustainable purchases include food that is locally grown, locally sourced, locally processed, or organic.
  • The cost percentage for 2014 increased by 0.6%. In terms of actual dollars, in FY 2014 we spent $10,656 more in sustainable purchases.
