Winter Closure: Building Managers

The Winter Closure program targets a two-week shutdown of building heating and ventilation systems, as well as custodial services. As part of the fall/winter Cardinal Green Buildings Campaign, participation in Winter Closure helps support building level sustainability and conservation efforts across campus.

What’s In It For You?

By helping your department conserve resources as a Cardinal Green Building, you are eligible to win participation prizes:

  • Participation: All buildings who participate in Winter Closure are entered in a raffle to receive cash rewards toward events/operations budgets.
  • Advanced Participation: All buildings who improve performance from the previous year are entered in a raffle to receive cash rewards toward events/operations budgets.
  • Building Manager Diligence: All building managers who submit the participation pledge by the are entered in a raffle to receive one of several $50 gift cards. Furthermore, the FIVE building managers with the highest number of building occupants who participate in the individual pledge receive an additional gift card.


Background and Results

Since 2001, the annual Winter Closure Program has served an important role in energy conservation at Stanford. Previously voluntary, winter closure became mandatory in 2003 via a program administered jointly by the Department of Sustainability & Energy Management and Zone Management. In recent years, SEM and Zone Management have also begun to target Thanksgiving and other extended holidays in a similar manner. Winter Closure specifically has resulted in a cumulative net energy cost savings of $4 million since its inception. In 2016, 14 buildings increased their participation level either from full exemption to partial participation or partial to full participation. Out of 248 zone-maintained buildings, 195 buildings participated to save:

  • 1.25 million kilowatt-hours of electricity
  • 1,570 million BTU of thermal energy saved (combination of hot water and process steam savings)
  • 58,400 ton-hours of chilled water savings
  • $315,000 in operating savings
  • 801 metric tons of CO2 emissions avoided

In 2015, the campus achieved the following energy and cost savings:

  • 1.4 million kilowatt-hours of electricity
  • 1,570 million BTU of thermal energy saved (combination of hot water and process steam savings)
  • 203,000 ton-hours of chilled water savings
  • $340,000 in operating savings
  • 806 metric tons of CO2 emissions avoided

In 2014, the campus achieved the following energy and cost savings:

  • 1.5 million kilowatt-hours of electricity
  • 3.9 million pounds of steam
  • $357,000 in operating savings
  • 840 metric tons of CO2 emissions avoided

In 2013, the campus achieved the following energy and cost savings:

  • 1.6 million kilowatt-hours of electricity
  • 3.8 million pounds of steam
  • $247,000 in operating savings
  • 838 metric tons of CO2 emissions avoided

In 2012, the campus achieved the following energy and cost savings:

  • 1.6 million kilowatt-hours of electricity
  • 3.8 million pounds of steam
  • $247,000 in operating savings
  • 838 metric tons of CO2 emissions avoided

In 2011, the campus achieved the following energy and cost savings:

  • 1.6 million kilowatt-hours of electricity
  • 5.7 million pounds of steam
  • 1,033 metric tons of CO2 emissions avoided
  • $266,000 in operating savings

In 2010, the campus achieved the following energy and cost savings:

  • 1.4 million kilowatt-hours of electricity
  • 3.8 million pounds of steam
  • $202,000 in operating costs
  • 778 metric tons of CO2 emissions avoided
