Smith College

Environmentally sustainable practices integrated into institutional operations

Smith College has made significant strides in upgrading its aging campus infrastructure with a persistent drive toward collecting data—and sharing it with their engineering students.

Smith's sustainability goals:

Carbon neutrality by 2030

Annual energy savings

$183,558

Annual MTCO2e savings

658

Annual MMBtu savings

9,340

In 2015, Smith College was experiencing a series of metering and data problems and was seeking a way to share their energy data with their engineering program for use on academic projects. Also, Smith’s 4,100-ton chiller needed significant work.

GreenerU implemented analytics-based diagnostics on 120 electric, steam, and chilled water meters. We identified 24 problematic submeters and recommissioned or replaced them as needed. We also integrated all 120 submeters into our data analytics monitoring platform, enabling Smith to organize and analyze energy data, identify energy savings opportunities, and provide opportunities for student and faculty to use energy data for academic projects and engineering coursework.

GreenerU also worked with Smith to develop a more cost-effective alternative to replacing an 1,000-ton chiller; instead we optimized existing chillers and overhauled their three 700-ton chillers, including retrofitting them with variable frequency drives. This saved Smith $800,000 in capital costs and is generating greater energy than the original project would have achieved.

GreenerU has also done comprehensive energy-efficiency improvements in several other buildings, including a campus center, a science laboratory building, and an indoor track and tennis facility.
