Sustainability - Energy & Climate Action


For several years, Endicott has been working to reduce the energy intensity of our buildings by retrofitting existing buildings with high efficiency equipment.   These efficiency measures have been successful in reducing operating costs, upgrading equipment, and reducing our environmental footprint by about 7% when compared to a “business as usual” scenario.

In addition, the College continues to negotiate multi-year contracts for electricity and natural gas as well as for renewable electricity in order to ensure price stability and predictability.   

Electrical Efficiency


Energy efficiency efforts at Endicott have been ongoing for a decade.  In the Fall of 2010, we began an annual cycle of targeted replacement of lighting, primarily motivated by electrical energy savings.   New lighting includes lamps and ballasts, LED lights, high efficiency outdoor lighting, and controls. 

Lighting replacement projects were identified by building and targeted by payback and magnitude of the savings.  National Grid provides incentives for these efficiency projects in the form of rebates that reduce the first cost of a project as well as on-bill interest-free financing.   The financing allowed Endicott to spread payment of the project over 24 months on the utility bill, thereby directly linking the capital cost with the operating savings.   Figure 1 shows the variety of projects.

Beyond efficiency, there are other important benefits of lighting upgrade projects are more difficult to quantify, but include:

-        Improved light levels:  for example the gymnasium light levels were increased to those required by our conference.

-        Reduced maintenance:  many new lamp types have significantly longer life than those they replace, reducing maintenance time.

-        New fixtures replace equipment that may have been 20 years old.


There are a number of challenges in measuring the actual results of our investment in energy efficiency, in large part, because it is impossible to measure something that does not exist.   In addition, the campus electric meters often meter a number of buildings together, the building use changes over time, and new construction adds load and changes it.     

Nonetheless, several meters have had few changes in their buildings’ use during the period for which we have data.  On these meters we can see the benefit of the efficiency projects directly.   Figures    2 and 3 show the measured effect of these projects.   In the Post Center, lighting was replaced throughout the building at the same time that the new Fitness Center was opened.

Campus Growth and Energy

The Endicott Beverly campus is growing with additional square feet from new buildings and expanded buildings.  In addition, many buildings are used for longer hours or for more days during the year.   Figure 4 shows the effect of this growth on our campus electricity use which increased by about 6% from 2010 to 2013.   The far right column represents the 2010 electricity use plus the electricity use of the three new  buildings that have opened since then (Marblehead, Business/Life Science, and Health Science building) and shows how electricity use would have increase in 2013 if no action had been taken.   Efficiency efforts have curbed electricity use by about 7%, effectively allowing us to bring on one of those buildings “for free”, when compared to a business as usual case.

Reducing Demand

Electric demand is a measure of the electricity needed at an instant and is independent of the hours of use.  So, reducing demand (kiloWatts) is something we can control; actual electricity use (kiloWatthours) is a combination of demand and hours of use.   Decreasing demand while increasing our square footage is a major accomplishment that indicates we are becoming less energy intensive on a space-by-space basis.  Figure 5 shows campus electric demand has decreased by 12% despite new growth.


Natural Gas Efficiency 

Natural gas is the College’s primary heating and hot water fuel.  Efforts have been made to improve efficiency by installing high efficiency condensing boilers and managing these systems with an energy management computerized system.  Most of these efforts have focused on replacing old equipment (boilers and chillers) with higher efficiency models as part of the regular replacement cycle.  National Grid rebates that exceed $40,000 have been applied to the projects.  Monitoring natural gas trends is difficult due to weather and building use variations.   Analysis in this area is beginning. 

In 2010 Endicott conducted a Greenhouse Gas Inventory.
