Energy-efficient pumping systems

Published:  30 March, 2011

BSRIA, energy efficient pumping

BSRIA has published a design guide to energy-efficient pumping systems based on research carried out in collaboration with BRE and a number of industry partners. The guide recognises that the potential for pump energy savings is substantial — with the best designed variable-flow systems using 82% less energy than the worst constant-flow systems.

Lack of regard for pump energy in heating and cooling applications can lead to other energy-saving opportunities being missed. For example, excess flow leads to lower differential between flow and return temperature, reducing the effectiveness of some low-energy/carbon heating and cooling sources.

The guide provides recommendations for building-services designers on the design of energy-efficient pumping systems.
