  1. Energy Trends

  2. Trift bridge 560’ long 333’ high

  3. Trift glacier 1948

  4. Trift glacier 2006

  5. 2 miles since 1948

  6. Do you believe?

  7. Industry 32% Buildings 40% Transport 28% Energy 39% of CO2 72% electricity Surprised?

  8. Industry 32% Buildings 40% Transport 28% Energy Res 22% Com 18%

  9. Even if you don’t believe… …believe in hard savings of 15% to 60%

  10. Size of the prize… O&M 7% to 28% Controls 7% to 23% Lighting 6% to 25% Equipment 3% to 15% Behavior 3% to 15%

  11. Making the invisible visible

  12. Making the invisible visible

  13. Why now?

  14. Electricity pricing US average electricity cost - $0.01 / kwh

  15. Natural gas pricing Commercial natural gas prices - $ / cu ft

  16. Efficiency is the cheapest form of clean power

  17. Net zero energy 20:20:20 BEQ LEED Energy Star

  18. Pilot phase 21 buildings 14.5M sq ft A- to C grades

  19. LEED Millions of sq ft certified

  20. Energy Star Millions of sq ft certified

  21. How?

  22. Intelligent buildings Day lighting Sub-metering Efficient lighting Occupancy sensing Variable speed drives Demand-based ventilation Continuous commissioning Utility automated demand/response Fully integrated building management system

  23. Smart Grid & Demand / Response

  24. What is the Smart Grid?

  25. Use of digital information and controls to improve reliability, security and efficiency of the grid.

  26. Use of smart automation systems that optimize the operation of buildings and homes.

  27. Installation of smart metersto enable real time pricing

  28. Deployment of demand / response

  29. The Problem Energy Demand Energy Cost Spot Market $2.00 Renewables $.30 Diesel Peaker $.25 Gas Turbine $.10 Coal $.06 Hydro $.04

  30. Efficiency Original load With energy efficiency 250 kW reduction Building power consumption - kw

  31. Demand / Response Original load With energy efficiency Building power consumption - kw With demand response

  32. Auto Demand Response Demand Response - a utility requests energy curtailment during an anticipated peak period where demand exceeds supply. Utility options are: Purchase power on the spot market Start up old generation plants Build new power plants (very costly) Rolling blackouts Demand / Response Auto DR is an automated way to achieve demand reduction.

  33. Demand response - lowest installed cost

  34. Thank you
