Meeting Goals
• Summarize ENERGY STAR Program vision
• Review EPA’s ventialtion fan research since last HVI meeting
• Introduce draft ENERGY STAR guidelines for ventilation fans
• Discuss draft and next steps
3
ENERGY STAR Philosophy
• Foster public-private partnerships – expand markets for energy-efficient products and reduce energy waste
• Reduce air pollution – decrease carbon dioxide and other emissions leading to climate change and urban smog
• Recognize the most energy-efficient product models in the market through the use of the ENERGY STAR label
• Maintain customer satisfaction – increase energy efficiency without sacrificing performance
• Encourage innovation and competition – develop energy-efficiency guidelines that are technology neutral and performance based

A Growing Suite of Products
New Product Development4 programs launched in 1998 and 1999• Tentative plans to launch 5-7 more programs in the remainder of
1999
• Potential New Products– Set-top boxes -Vending machines -Reach-in fridge/freezer– Ventilation fans -Ceiling fans -Traffic signals– Ice cube makers -Air purifiers -Telephony– Visi-coolers -Water coolers -Dehumidifiers– Wall packs -Motors -Unitary AC
– Humidifiers
16
Why Ventilation Fans?
•Diverse products – reliably large and growing installed base
•Changing usage patterns
•Potential for more energy-efficient design
•Manufacturer interest in program
•Changing building codes and indoor air quality concerns from tighter
homes
17
Market Observations
• Diverse products• At least 6 functional uses and categories
• Installed base = 143 million
• Annual energy consumed = 5.6 billion kWh
• Residential market = 7 million units sold/yr.• $300 million in sales
• Sales growth = 1% per year
• 5 million new units to new homes– 2 million units sold retail
• __ % bought by builders
• __ % bought by consumers
18
Market Observationscontinued
• Great divergence in product efficiency
• Components and sub-components responsible – Shaded pole vs. permanent split capacitor motors
• Stator laminations
• Shading quality
• Air gap
• Wiring
• Capacitors
– Impeller • Scroll
– Housing
– Auxiliary controls• Timer, humidity and motion sensors
19
• EPA reviewed data and designs from 51 fans
• Identified those with efficiency in the 75th percentile to find those with very high efficiency
- cfm/W level > 3.4
- cfm range 50 to 1,200
• Surprising outcome -- No clear trend in energy efficiency verses capacity.
• Conclusion -- More complex analysis needed to control for component type

The Role of ENERGY STARin the Fan Market
• ENERGY STAR can be a catalyst for long-term market transformation
– Low level of market penetration of energy-efficient fans • Current level approximately 10%
– Large variance in product energy efficiency • .5 cfm/watt -- 5 cfm/watt
– Easy way for builders and consumers to identify the most efficient products
• Testing Guidelines - any changes necessary?
• Time Line - Recommended Industry Events/Milestones
