Tracking Energy Savings from the Energy Star 3.0+ 30% Televisions Program By Christina Steinhoff
Outline • Program Background • Energy Savings Rate Calculation for 2009
Background: Energy Star 3.0+ 30% Definition • Maximum On Power Mode Energy Consumption • Standby • Must not exceed 1 watt in standby mode • User Information Requirement Example Area=437.07 inches squared Energy Star 3.0 =.2*437.07+32=119 watts Energy Star 3.0+30%= 84 watts (30% reduction) • Note: Testing is based on the international test procedure IEC 62087, tested at default setting. The test accounts for on supply voltage (115v), ambient temperature and humidity.
Background: NEEA Energy Star Televisions Tracking System • The 2009 opt-in program provided retailers incentives for sales of Energy Star 3.0+ 30% televisions. • Energy Solutions tracks the sales as well as other details. • Model number • Energy consumption • Tier (Energy Star 3.0 Plus 30%, Energy Star 4.0, Energy Star 5.0) • Zip Code of retail location • Screen size • The tracking system places the sales in seven buckets based on the screen size. Source: Energy Solutions. Feb 2010. NEEA Electronic Source Data for Sept.-Dec. 2009.
Background: Measuring Energy Savings • NEEA measures savings from market intervention. • Savings come from the efficient option over the inefficient option. • Non-qualifying Energy Consumption is the consumption of televisions with less than Energy Star 3.0+30% efficiency in Q1 2009. • Comes from QDI Strategies and Energy Solutions • Data source: NPD Group, Consumer Electronics Association, QDI Strategies’ tracking of the Business and Consumer Electronics program; and the Energy Star Products List. Energy Savings by Size Category= Non Qualifying Unit Energy Consumption Prior to the Program – Qualifying Unit Energy Consumption Baseline Period Discussions with Retailers Incentivized Units Sold (Sept.-Dec.) Q1 2009 Q2 2009 Q3 2009 Q4 2009
Results: Savings Rates • NEEA will apply these saving rates to its estimate of total Energy 3.0+ 30% television sales by size category in the region. • The weighted average savings rate for the incentivized units is 114 kWh/television. • This rate is highly dependent on the screen size. Note: The Energy 3.0+ 30% average energy consumption comes from 112,477 observations. The calculation measures savings from on power mode (5.2 hours/day for 365.25 days per year)
Future Work • In 2010, we will be tracking the savings for Energy Star 4.0 and Energy Star 5.0. • Using the same seven screen size categories.
