Tracking Energy Savings from the Energy Star 3.0+ 30% Televisions Program
By Christina Steinhoff
Outline
Program Background Energy Savings Rate Calculation for 2009
Maximum On Power Mode Energy Consumption
Standby Must not exceed 1 watt in standby mode
User Information Requirement
Background: Energy Star 3.0+ 30% Definition
Energy Star 3.0 Specifications(Effective Nov. 1, 2008)
Area < 680 in2 PMax = 0.200*A + 32
680 in2 ≤ Area < 1045 in2 ≤ Area
PMax = 0.240*A + 27
Area ≥1045 in2 PMax = 0.156*A + 151
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.

Baseline Period
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.

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.

Energy Savings Calculation by Screen Size Category (kWh/Unit)
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.
Tier 1 Energy Star 3.0+ 30% to 4.0Tier 2 Energy Star 4.0 to 5.0Tier 3 Energy Star 5.0 Plus
