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'll be eligible to win participation prizes with a total value of up to $1,500:

  • Participation: All buildings who participate in Winter Closure will be entered in a raffle to receive one of several $250 cash rewards toward events/operations budgets.
  • Advanced Participation: All buildings who improve performance from the previous year will be entered in a raffle to receive $250 cash rewards toward events/operations budgets.
  • Building Manager Diligence: All building managers who submit the participation pledge by the November 13 deadline will be entered in a raffle to receive one of several $50 gift cards.

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. The program has resulted in a cumulative net energy cost savings of $3.3 million since its inception. The campus continues to work towards its goal of 75 percent participation (full and partial) during winter closure. In 2014, 20 buildings increased their participation level either from full exemption to partial participation or partial to full participation. Last year, out of 247 zone-maintained buildings, 119 buildings fully participated and 62 buildings partially participated to save:

  • 1.5 million kilowatt-hours of electricity
  • 3.9 million pounds of steam
  • $357,000 in operating savings (bringing the total campus savings since 2001 to $3.3 million)
  • 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 (bringing the total campus savings since 2001 to $2.96 million)
  • 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 (12 percent increase per day from 2010)
  • 5.7 million pounds of steam (41 percent increase per day from 2010)
  • 1,033 metric tons of CO2 emissions avoided (25 percent increase from 2010)
  • $266,000 in operating savings (32 percent increase from 2010)
  • $2.5 million in operating savings since 2001

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

  • 1.4 million kilowatt-hours of electricity (48 percent increase from 2009)
  • 3.8 million pounds of steam (87 percent increase from 2009)
  • $202,000 in operating costs (54 percent increase from 2009)
  • 778 metric tons of CO2 emissions avoided (63 percent increase from 2009)
