Objectives of the Program• Target Audience
plant managers, facility operators, and company officials • Outreach Message
interdependency between air emissions, energy consumption, and energy costs
• Mitigation Effort voluntary actions to reduce air emissions using Energy Efficiency (EE)
a. reduced energy useb. cost savingsc. fast pay back time• Reporting Assistance
educate and assist facilities about multi-pollutant air emission calculations
assist facilities with understanding requirements of EPA GHG Reporting Rule

Why Energy Efficiency?4
32-56% 8%
100% Energy Input
Indirect Benefit30-51% Total Efficiency
Direct BenefitFuel Savings• Energy is a significant operating cost
(5%)• Smart companies have a long-term EE
plan• EE projects pay for themselves• EE is a free air pollution “control”

Lessons Learned
• Large companies are having an assessment every 5 years
• Many decision makers are non-technical and have no time
• Need to express EE projects terms of dollars for
• Implementation may take several years
• Lighting and steam reductions have the biggest impact for cost
• Need to show facilities how to market EE in sustainability reports
• EE programs can make an impact to air quality over time

a. Communicate the importance of EE in reducing air pollution
b. Maintain partnerships with NCSU & WRP - assessments & workshops
c. Publish case studies to educate facilities
d. Encourage lumber & furniture industry to use woodwaste trading
programs
e. Communicate utility EE rebate opportunities
f. Pursue funding of EE implementation
