Energy performance
Level: Core
A majority of the total environmental load of a projector consists of energy use in the use phase. Therefore it is important to set requirements that the projector should have a low energy use in on mode.

Criterion text
Projectors must fulfil energy requirements in on mode based on image size Amax, see also "Energy efficiency, projectors" (only in Swedish).
Amax/office
| Size | On mode, normal operation |
| ≤ 3 m2 | ≤ 260 W |
| ≤ 6 m2 | ≤ 310 W |
| > 6 m2 | ≤ 310 + 150 * (Amax - 6) W |
|
For projectors with a throw ratio of ≤ 0.82, 30% more energy consumption is allowed. |
|
Amax/video
| Size | On mode, normal operation |
| ≤ 6,6 m2 | ≤ 260 W |
| ≤ 13,3 m2 | ≤ 310 W |
| > 13,3 m2 | ≤ 310 + 150 * (Amax - 13,3) W |
|
For projectors with a throw ratio of ≤ 0.82, 30% more energy consumption is allowed. |

Verification
The supplier shall, upon request, be able to present any of for example the following:
- Valid license for example for the following label:
- TCO Certified projectors, generation 9.
- Technical documentation verifying that the energy levels are below the limits in the requirement. This may for example be test report or product information sheet.
Proposed follow-up
Labelling
If a supplier uses an ecolabel to prove that the requirement is met, it must be ensured that there is a valid license, certification or equivalent for the product in question. This can be checked: TCO Certified.
Testreport/product information sheet
Check the technical documentation for energy performance to verify that the requirement has been met. The documentation may consist of test reports where the energy performance of the projector has been tested. It may also be product information sheets, where information on energy performance is included. It should be clear in the testreport or in the product information sheet that the energy performance has been measuered in accordance with the methods specified in the requirement.
Environmental goals
Motive
Energy efficient products lower the environmental impact by a lower energy demand in the usage phase.
The requirement balances image quality with energy performance, since t is relevant to measure the energy consumption at a given image size and image quality to achieve comparable results.
