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
2
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 3

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
16
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
17
Market Observations
continued
• 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 18
Fan Efficiency Observations
• EPA reviewed data and designs
from 51 fans
• Identified those with efficiency in
the 75th percentile to find those Ventilating Fan Efficiencies
with very high efficiency

The Role of ENERGY STAR
in 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
22
EPA’s Promotion of
Ventilation Fans
Focus on key distribution channels to reach builders and
individual consumers
• Retailers
• Utilities
• EPA and DOE resources
• ENERGY STAR HIP and Homes programs, DOE FEMP program
• Advertising mediums
• Print, internet and TV
• Trade shows
• Procurement efforts
