Re: [EnergyPlus_Support] bhp vs hp LEED simulation

[Karen Walkerman <kwalkerman@xxxxxxxxx>]

Hi Oscar,

I am more familiar with smaller pumps where the pump and motor are connected.  What I do is use the pump curve to determine the power draw at the pump at design conditions and use that number.

Hello Oscar,

If you are dealing with the proposed case, you should aways consider the worst data that your building will use. So, consider the next commercial motor size and calibrate it with a schedule.

Hello group

I am modeling a building for LEED purpose. If someone can give me some lights I will appreciate

What is the correct approach when simulating pumps and fan power in the proposed case?. size the electric motors with the bhp or the next commercial motor size. I mean the if the condenser water pump has 15.3 bhp but the next available motor size is 20 hp. the pump will not use 20 hp.

Thanks in advance.
