Optimise the counter weight and decoration weight of lift car
Consider retrofitting the lift car decorations to reduce the weight of the lift car.
Consideration
To consult the Registered Lift Contractor on the feasibility and how to optimise the savings such as the performance characteristics of the motor set and the need to adjust the counter weight.
Estimated Saving
kW_LIFT * MLIFT * LFLIFT * %SAVE * OPHR,yr
Assume %SAVE = 10 to 15% for ±10% change in counter weight or provided by the manufacturer
Where LFLIFT = 0.35
OPHR,yr = hr/day*day/wk*52
