Calculating Total Watts, CO
To calculate the total power consumption in Watts for the library, add up all the
applicable wattage values for the library configuration from
To calculate kilograms of CO
constant. Use the constant that is applicable for your country (0.02497 for US).
To convert electrical values to Btu/hr, multiply the number of watts by 3.412 (1 W
=3.412 Btu/hr). Many manufacturers publish kW, kVA, and Btus for their equipment.
Use the information provided by the manufacturer. Otherwise, use the formula below.
3.41214 x Watts =Btu/hr

Power Consumption Example

Quantity Component Description
1 SL3000 Base (including one ECM, one robot, one CAP)
16 LTO7 Tape Drives
-- Total
Emissions: 933W x 0.02497 = 23.3 Kg of CO
■
Power consumption: 933W x 3.412 = 3,183 Btu/hr
