• Refrigerators = ~6% of U.S. home energy use
• 50% more efficient than current Federal minimum energy standards
• 20-25% below current ENERGY STAR® products and the future (2014) Federal minimum energy standards
• Technologies:
– Sequential dual evaporator refrigeration cycle
– Variable capacity compressor
– Thermal load shifting
– Vacuum insulation panels
– Phase change material or PCM-coupled evaporator
– Adaptive controls
Next Generation Refrigerators Promise Even More Savings for Consumers

Future Solid State Lighting Promises Even Bigger Impacts…
• R&D Goals:
– LED efficacy (warm white): 96 lm/W (2010) → 253 lm/W (2020)
– LED price (warm white): $18/klm (2010) → $1 klm (2020)
• Market achievements:
– L-Prize 60-watt replacement LED bulb from Philips (93.4 lm/W)
– Philips Lumileds’ LUXEON Rebel LED delivers 139 lm/W
– Cree’s high power white LEDs deliver 121 lm/W
– Universal Display Corporation demonstrates first U.S. OLED luminaire

With no/ultra-low load homes, research
addresses other loads, renewables, and
transaction process
As thermal loads continue to shrink,
reducing other loads become critical. Also need to address ‘O’
value in trans. process.
Thermal loads becoming so small,
need low-load HVAC and whole-house dehumid. due to
longer swing seasons.
Tighter, better insulated homes demand water management,
ventilation and IAQ.
As codes ramp up, critical research
continues to address effective insulation, air sealing, and windows.
With advent of insulation in codes,
critical research addresses effective
insulation, air sealing, and windows.
