[EnergyPlus_Support] Re: Automatic operation venetian blinds energy consumption
Jean
Thanks. However, when you say small amount of energy what range are you talking of? Do you have some reference with data on this? I mean, stand by energy consumption is small but when added is significant. So I am trying to pin down this small amount of energy with little success. The nominal power of the motor is not so small. Multiplied by many windows may be significant.
