Existing Infrastructure: Monitoring and Reducing Energy Consumption

USDA Forest Service

Energy Conservation and Awareness

Energy Act of 2005 (EPACT 2005)

USDA DR 5500-001 June 19,2006

Reduce energy intensity by 20% by 2015 (baseline 2005)

Executive Order #13423 January 26, 2007

Reduce energy intensity by 30% by 2015 (baseline 2003)

Reduce fleet energy consumption of petroleum products by 22% by 2015 (baseline 2005)

Electronic products must meet Energy Star® and EPEAT requirements

Eastern Region Courageous Conservation

10-year goals

#4: Walking the Talk for Sustainability Sustainability framework and change our agency culture Environmental management system (EMS) Procure green product, green facilities Appropriate alternative energy systems Energy-efficient FS fleet Show how our sustainability practices can be applied in

individual lifestyle



Why do we want to save energy?

Save money

Energy Independence--less dependency on imported energy from rogue countries and/or terrorist supporting countries.

Climate Change--Reduction of greenhouse gas emissions (CO2)

What is energy efficiency? Doing what we do, and finding ways to do it expending less energy and cost.

Action items for Duluth S.O. to reduce energy consumption:

Turn off computers daily 11%

USDA letter of July 28, 2008, requires computers to be set up to hibernate. X



Turn off computers daily 11%

A NOT so successful story:

Most computers, monitors, printers, and copiers that the FS buys are NOT Energy Star nor EPEAT compliant, nor have any power save functions been activated.



Turn off 1/3 of lights 6%



Set-back thermostats after-hours 4% Turn off printers daily (timers) 2%



Turn off pop machine daily (timer) 1% Turn off coffee machine daily (timer) 1%

24/7 programmable timer---3 month payback



Turn off parking lot lights at 10pm 1%



Turn off air movement fans after-hours 13%
