Renewables as anEnvironmental Solution?



Energy Management is the Quickest, Cheapest, Cleanest Way to Extend World Energy Supplies

Energy management can provide 2.5 times

the environmental impact of renewable energy


Global CO Extend World Energy Supplies2 Levels Exceed 400 ppm


Energy Management 101 – Example Extend World Energy Supplies

  • Management commitment

  • Manual daily meter reading

  • Operational changes only

10


Energy Management 101 Extend World Energy SuppliesThe Building

20-Story Office Building:

  • 200,000 ft2

  • 5 years old, no energy conservation

  • Complex, energy intensive HVAC systems

  • High utility bills

  • No building automation system

11


Energy Management 101 Extend World Energy SuppliesHow It Worked

Actions by Facility Manager:

  • Reviewed operations ideas with building engineer and design engineer

  • Reviewed daily meter data for impact, intuitively adjusting for weather

  • Harassed/complimented building engineer daily on performance

12


Energy Management 101 Extend World Energy SuppliesHow It Worked

  • Actions by Building Engineer

  • Aligned building schedules with occupancy times

  • Raised cold deck temperature

  • Lowered hot deck temperature

  • Outside air was introduced only during occupied hours

  • Reduced duct pressures

Savings in one year: 33%!

  • 2009 – 2012 Total Energy Savings (weather-normalized)

  • Total Savings = $8,665,000

  • $8,665,000 ÷ 0.04 (margin) =

  • $216,625,000 equivalent revenue

  • $216,625,000 ÷ 4 years =

  • $54,156,250 equivalent revenue per year
