The major energy savings with Active Chilled Beam systems is in fan power. What is the situation with pumping energy?
There is a modest increase in total pump energy as a result of the secondary water system. However, while the total pump energy for ACB systems, primary and secondary, is higher than an all-air system, it does not significantly reduce the energy savings achieved with the fan power. As with any exercise in comparing energy usage between alternative systems, each installation must be looked at separately.
