Emerging Technologies and Business Practices
Stories

• September 2008

2
Approach

• Contract with WSU Energy Extension
• Review literature, programs, organizations
• Develop list of measures practices with key
  characteristics
• 250 to 300 measures practices considered .. so
  far

3
Organization Consulted

• ACEEE
• BC Hydro
• BPA
• California Lighting Technolgy Center
• E Source
• ECOS Consulting
• Edison Electric Institute
• Emerging Technology Coodinating Council
• Federal Energy Management Program

• National Labs
• Natural Resources Canada
• Puget Sound Energy
• Seattle City Light
• Sacremento Municipal Utility District
• UC Davis
• U.S. Dept of Energy
• WSU Energy Program
• Washington Technolgy Center

4
Selection Criteria

• Significant savings likely within 15 years
• Advanced stages of development
• Commercially available or
• Ready for commercialization
• Not yet in wide use in PNW
• Little negative impact on the service provided
• Not fully considered in 5th Power Plan

5
Major Findings So Far

• No Silver Bullets
• Many Incremental Improvements
• Proliferation of Niche Applications
• Development of Business Practices for Energy
  Management
• Some Potential Breakthrough Technologies
  Warrant RDD Now

6
Findings in Three Categories
Improvements to Existing Technology. Gains in
cost, efficacy, applicability or measure life.
Improved Tech
Changes to Design Business Practices
Systematic business strategies that improve
measure applicability, penetration and
persistence Design Operations
New Improved Practices
New Products Technology. Breakthrough
technologies not previously considered viable.
Includes both direct and enabling technologies
products.

A Sampling of New Technologies Business
Practices

• Long-life Fluorescent Lighting
• Low-Lift Cooling
• Improved Business Practices
• OLEDs Organic Light Emitting Diode
• Server Virtualization
• Electron Stimulated Luminescence

8
Long-life Fluorescent Lighting

• Key to long life T5s with program-start ballasts
• Philips and Sylvania lamps 46,000 hours
• Kumho Electric 100,000 hrs!
• Work well with occupancy sensors

9
Why do we care?

• Lower implementation and maintenance costs
• Now competes with SSLs for longevity
• Less embodied energy

10
Downsides of LED Lighting for General Service
Lighting

• 100,000 hours is only for colored lights
• White lights are still not consistent color
• Currently very expensive
• Difficult to achieve even light distribution

11
Low-Lift Cooling

• 1 of 5 Technology Option Sets to be developed
  by the DOE net Zero Energy Buildings program by
  2010
• A package of five technologies that work together
  as a system
• According to PNNL models save 30-74 of cooling
  in new buildings
• BPA to be doing field trials

12
Low-Lift Cooling Option Set

1. Peak-load shifting by thermal energy storage
2. Dedicated outdoor air supply with enthalpy heat
   recovery from exhaust air
3. Radiant heating/cooling system panels or floor
4. Low-lift vapor compression cooling equipment
5. Advanced controls at equipment and system
   (supervisory) levels

13
Business Practices

• Not Technologies
• Strategies that
• Create new savings due to synergies
• Allow higher penetration of measures
• Improve persistence of measures
• Significant new conservation potential

14
Improved Strategies PracticesA Sampling

• Integrated Building Design
• Energy Management Business Practices
• Analyzing how corporate decisions get made
• Continuous Energy Improvement, Envinta 1 to 5,
  Enterprise Energy Management
• Data Center Optimization
• Building Commissioning Practices
• Monitoring-Based Commissioning

15
Organic LEDs

• Exciting potential Can light up entire ceiling
  or clothes
• Projected to be more efficacious than fluorescent
  lamps
• In screens, more efficient and much more contrast
  than LCD
• For use in screens for now. Some lighting
  products in 3-4 years.

16
Electron Stimulated Luminescence (ESL)

• Same efficiency, life, and cost as CFLs
• No mercury
• CRI of 95
• Instant-on
• Easily dimmable
• Can use standard glass bulbs
• Reflector bulbs available in 2009
• More info www.vu1.com

17
Server Virtualization

• Can use one box as several servers
• Can cut computing energy substantially (over 50)
• Lower equipment costs
• Greatly decreases cooling loads
• How do we treat this?

Refrigerated Display Case

• Replaces T-12 T-8 fluorescent
• Long hours of operation per year (18 to 24
  hours/day)
• Cool ambient application potentially long life
• Saves refrigeration energy too
• Savings multiplier 1.3 to 1.7
• With occupancy sensors more savings
