5Checking Energy-Saving Effect [CARBON METER]

This feature will show energy-saving effect in terms of CO2 emission reduction (kg) when the projector’s [ECO MODE] is set to [ON]. This feature is called [CARBON METER].

There are two messages: [TOTAL CARBON SAVINGS/TOTAL COST SAVINGS] and [CARBON SAVINGS-SESSION]. The [TOTAL CARBON SAVINGS/TOTAL COST SAVINGS] message shows the total amount of CO2 emission reduction and the electricity cost savings from the time of shipment up to now. You can check the information on [USAGE TIME] from [INFO.] of the menu. (→ page 77)

The [CARBON SAVINGS-SESSION] message shows the amount of CO2 emission reduction between the time of changing to ECO MODE immediately after the time of power-on and the time of power-off. The [CARBON SAVINGS- SESSION] message will be displayed in the [POWER OFF/ ARE YOU SURE?] message at the time of power-off.

TIP:

•The formula as shown below is used to calculate the amount of CO2 emission reduction.

Amount of CO2 emission reduction = Power consumption in OFF for ECO MODE – Power consumption in ON for ECO MODE x CO2 conversion factor.*

*Calculation for amount of CO2 emission reduction is based on an OECD publication “CO2 Emissions from Fuel Combustion, 2008 Edition”.

•This formula will not apply to the power consumption which is not affected by whether [ECO MODE] is turned on or off.

•The factors for [TOTAL COST SAVINGS] can be changed from the menu ([CARBON CONVERT] and [CURRENCY CONVERT]). (→ page 73, 74)

•The currency unit for [TOTAL COST SAVINGS] can be changed from the menu ([CURRENCY]). (→ page 74)
