Hi, We have 2 number domestic hot water return pumps (100 watts each). These are the only two pumps we are specifying within the scope of this fit-out. When we half the flow-rate we cannot reduce the pump kW rating to 30%. We are using a leading manufacturer in pumps. As the overall effect of these pumps will be minimal to the over all project. This seems very onerous to achieve even with new pumps using variable speed drives. Will we lose this credit for not achieving this pump performance ?

Those pumps are not HVAC equipment and are not even regulated by 90.1. So if you don't have any HVAC scope of work you would not be eligible for this credit.
