Since 2001, the annual winter closure has been a great energy conservation solution for the campus. Previously voluntary, winter closure became mandatory in 2003 via a program administered jointly by the Department of Sustainability and Energy Management and Zone Management. It targets a two-week shutdown of building heating and ventilation systems, as well as custodial services. The cumulative net energy cost savings since 2001 total $2.7.5 million.
The 2012 “Turn Off For Break” Campaign continued to build upon past successes and save energy across campus. The following savings were achieved during the winter closure:
- 1.8 million kilowatt-hours of electricity (a 17% increase over 2011)
- 3.5 million pounds of steam
- $250,000 in operating savings (bringing the total campus savings since 2001 to $2.75 million)
- 882 metric tons of CO2 emissions avoided
The campus continues to work towards its goal of 75% participation (full and partial) during winter closure. This year, out of 247 Zone-maintained buildings, 108 buildings fully participated and 60 buildings partially participated. Of the buildings that participated this year, a total of 6 buildings increased their participation levels (moving up from no participation to partial or from partial to full).
To incentivize participation, the Office of Sustainability offered $2500 in participation prizes, awarded in three separate categories; for all participating buildings, buildings that increased their participation level, and for outstanding individual contributors. Congratulations to the raffle winners below:
- Mitchell Earth Sciences Building is the Participation Winner.
- Bechtel International Center is the Performance Improvement Winner.
The individual performance champion award was given to two outstanding individuals who went above and beyond to ensure the closure ran smoothly.
- Denise Kahwajy (GSB Facilities) Denise took the time to confirm scheduling needs by building and floor in the eight buildings of the Knight Management Center complex in order to optimize energy savings.
- Mike Ditommaso (HVAC Controls Tech) Mike has assisted with winter closure since the program began over a decade ago. Mike has always made sure that his assigned buildings were set to minimize energy usage during the two week break and is always willing to help in other buildings.

The performance goal for the 2011 winter closure was to increase energy and cost savings from the 2010 curtailment by at least 10%. The campus exceeded that goal once again, and achieved the following savings:
- 1.6 million kilowatt-hours of electricity (12% increase per day from 2010)
- 5.7 million pounds of steam (41% increase per day from 2010)
- 1,033 metric tons of CO2 emissions avoided (25% increase from 2010)
- $266,000 in operating savings (32% increase from 2010)
- $2.5 million in operating savings since 2001
In 2010, the campus achieved the following increase in energy and cost savings:
- 1.4 million kilowatt-hours of electricity (48% increase from 2009)
- 3.8 million pounds of steam (87% increase from 2009)
- $202,000 in operating costs (54% increase from 2009)
- 778 metric tons of CO2 emissions avoided (63% increase from 2009)
