Renewable Energy - Solar

• 9 kilowatt solar array at our facility in North
  Carolina
• Subsequently added passive solar wall and
  skylights
• 17 kilowatt solar array at Interface Flooring
  Systems in LaGrange, GA
• 128 kilowatt solar array at Bentley Mills
  facility in Southern California
• Combined solar capacity offsets approximately 144
  tons of CO2 per year

Non-traditional Engineering Approaches to Energy
Efficiency

• IFG South, Elkin, NC HVAC system for Weave 2
• -Engineering completed by traditional engineering
  practices just prior to Interface purchase
• -Interface brought in non-traditional engineers
  to take a different approach

IFG Weave 2

• Traditional System Non-Traditional
• -600 Ton Chiller -200 Ton Chiller
• -New doors and windows
• -Insulated walls
• ceiling, painted
• equipment
• -skylights and new
• efficient lighting
• -new heat and humidity
• system

IFG Weave 2 - Results

• 80 Original Capital Cost
• Estimated 375,000 kWh per year electrical savings
• Emissions reduction estimates from electrical
  savings
• -637,000 pounds of CO2
• -1819 pounds SO2
• -2067 pounds NOx
• Less capital cost, less operating costs, less
  emissions And a much better work environment!

Interfaces Approach to Energy
13
What, Where, Why, and How Much

• Know WHAT you use for energy (electricity,
  natural gas, fuel oil, compressed air)
• Know WHERE the energy is used
• Understand WHY you use it in each application
• Measure HOW MUCH energy you use and understand
  how the use is influenced
• Understand HOW you pay for energy and the key
  levers

14
Admit What You Dont Know

• Energy efficiency is not just turning off lights
  and purchasing Energy Star products
• Traditional engineering approaches dont includes
  systems assessments
• Doing things the way they have always been done
  will not provide different results

15
Leverage Resources

• Free efficiency audits including energy systems
• Financial incentives by various governmental
  entities
• USDOE
• Efficiency Maine
• Companies willing to bear the cost and share the
  savings
• Work with other businesses who have similar needs
  and interests

Energy Efficiency is a moving target develop
an energy plan - update it regularly
