Accuracy and Precision of

Measurement Equipment 

DOE is proposing input and voltage frequency requirements for all tests •Power supply providing voltage of 115 V at 60 Hz •Total harmonic distortion within 5% •Power factor measurement •Uncertainty requirements no greater than 2% at a 9confidence level 

24 | Building Technologies Program

Light Measurement Device (LMD) Specification

• DOE proposes to allow the use of both contact a

distance luminance meters. 

• DOE proposes to set specifications for the LMD

ensure results are similar for both meters. 

– Accuracy of 

± 2 percent (

± 2 digits) of the digitally dis

value and repeatability within 0.4 percent (

± 2 digits) v

– Acceptance angle of 3 degrees or less. 

Issue 2 - DOE seeks comments from interested parties on the LMD equipment specific

proposed in this NOPR. 

25 | Building Technologies Program 
Test Room and Setup 

Test should be conducted under standardized se

– Room illuminance shall not exceed 1.0 lux while in dark 

conditions 

• Ambient Temperature and Humidity 

– Temperature: 23°C +/- 5°C 

– Relative Humidity: 20% - 80% 

• Signal Source and Generation

Luminance Test 

DOE NOPR proposes testing in two picture set

• A luminance test has been included to allow for o

policy makers to use in their specifications to preoverly dim home picture settings, including: 

– Energy Star – California Energy Commission 

• The luminance test will be conducted in both hom

retail picture settings to determine a ratio. 

• The on mode power consumption test will only be 

conducted in the home picture setting. 

29 | Building Technologies Program 
Luminance Test 

• Home Picture Setting 

Definition - the picture setting which is recommended by the manufacturer from the initial set up menu or the mode that the television comes shipped in if no setting is recommended. 

• Retail Picture Setting

Definition - the preset picture setting in which the TV produces highest luminance during the on mode conditions. 

• Easy-to-Access Picture Settings 

– DOE is currently considering testing these settings 

Issue 4 - DOE seeks comments from interested parties on its proposal to conduct lumi

home picture setting and retail picture setting. For testing on mode energy consumptcomment on its proposal to test in home picture setting, along with its consideration to in both the highest and lowest energy consuming picture settings (or brightest or dimmpicture settings.

On Mode Tests 

There are two methods for testing on mode e

consumption depending on initial as shipped 

ABC Enabled (bydefault) • Room illuminance levels • Method for creating 

illuminance levels 

ABC Disabled (bydefault or N/A) • Tested in home mode 

42 | Building Technologies Program

On Mode Tests (ABC Enabled) 

Different methods can be used for creating room

Direct light Diffused 

DOE proposes to shine light directly at the ABC sensor. DOconsidered alternatives such as a diffuse light source, but dthat such alternatives would not be easily repeatable.

Different types of lighting can be used as a light 

Incandescent Compact Fluorescent Light-Em

DOE proposes to use a halogen incandescent light source. Tsource has a continuous spectral distribution, and DOE beliesufficient for creating a repeatable lighting condition.

On Mode Tests (ABC Enabled) 

Issue 9 - DOE seeks comments from interested parties on the method for creating 

illuminance levels including both the direct light method, that it proposed in this NOdiffused light method, considered in this NOPR. DOE also seeks comments from iparties on setting a color temperature range and a potential warm up period assocother light sources in that range.

procedure for TVs with ABC enabled by default.

49 | Building Technologies Program 
Testing TVs with ABC Enabled 

• IEC 62087-2011 and ENERGY STAR v5.3 currently 

ABC testing at 0 lux and greater than 300 lux. 

• A recent study* demonstrated that ABC is often impl

in a manner that does not take full advantage of poteenergy savings. 

• TV luminance at 0 lux is sometimes very dim. • Some TVs implement ABC using a gradual response 

others utilize a step function. 

• Measurements at only 0 lux and greater than 300 lux 

result in reported energy consumption values that arrepresentative of actual use. 

• Actual room illuminance in homes is uncertain, thoug

studies have provided preliminary results.

Room Illuminance in Homes 

• Prior to 2011, very limited data 

on representative room illuminance values found in homes. 

• 2011 Japanese study found 

that most common range was 50-75 lux, with 50%+ of measurements at 100 lux or less. 

• Not necessarily indicative of 

U.S. homes, however.

Summary of Room Illuminance

Studies 

• 0 lux is an extreme condition (occurring less than 0.2% in 

data) and allows for artificial behavior during testing. 

• 300 lux is extreme condition occurring less than 5% of the 

though does generally correspond to maximum TV lumina

• The peak of the distribution occurs between 10-15 lux. • Over 30% of data in all 3 studies are at or below 10 lux. 

• Over 75% of data in all 3 studies are at or below 50 lux. 

• Over 85% of data in all 3 studies are at or below 100 lux 

• Future home illuminance studies should include a represe

household sample, and span a range of dates during the yWeekends and weekdays must be appropriately sampled

61 | Building Technologies Program 
On Mode Tests (ABC Enabled) 

• Some stakeholders have suggested 0/12/35/300 lux 

measurement points, in comments to ENERGY STA

• Some stakeholders have suggested keeping 0/300 l

third measurement point near 10 lux, in comments to ENERGY STAR. 

• CLASP recommends three measurement points betw

and 100. This is consistent with DOE’s proposed lev10/50/100/300 lux. 

• If one picks the 25th, 50th, and 75th percentiles from i

studies, then the illuminance values are 5/15/45 lux. Extending logarithmically adds 135 lux, which would represent saturation. 

• If one picks the 12th, 37th, 62nd, and 87th percentiles f

home studies, then the illuminance values are 1/10/3lux. Extending to 300 lux would represent saturation

Issue 8 - DOE seeks comments from interested parties on whether there should bthe reduction in display luminance achieved from ABC, and how a minimally accepluminance value should be established. DOE also seeks comment from interested its proposal to test TVs shipped with ABC enabled at room illuminance levels of 10and 300 lux and their respected tolerances. DOE additionally welcomes comments these outputs should be weighted and combined.

Preliminary Observations 

• Little difference in how the TV displays 3D conte

(whether via Blu-ray, converted Blu-ray, or convethe TV) 

• Difference in energy consumption between 3D a

modes – significant and variable 

• Some difficultly with different manufacturers’ pro

Preliminary Conclusions on 3D

NOPR. 

• DOE explored two alternatives for including 3D 

procedure in the future. 

Issue 10 – DOE seeks comments from interested parties on 3D testing. DOE speccomment on its two methods under consideration for a future rulemaking which incconverting the 2D IEC dynamic broadcast-content video signal to 3D using a real tconverting Blu-ray player or creating a 3D version of the IEC dynamic broadcast-cosignal. DOE also seeks comments on how it can best work with the IEC and intereto promote the development of a 3D test procedure.

• Measuring screen luminance of 200 nits 

– If LMD displays “200.0” then 2% will be: 

• ± (2/100) * 200 = ± 4 nits 

– The least significant digit is 0.1 nits, there

• ± 2 digits = ± 0.2 nits 

– Total accuracy must be within:
