Eurovent proposal for information requirements for NRVU with HP and HRS

This Position Paper proposes a harmonised approach for the evaluation of performance of bidirectional NRVUs solely with a passive HRS and NRVUs with an HRS and a Heat Pump for heat recovery. It aims at an unequivocal comparison of heat recovery efficiency and specific electric power input for these two different types of NRVUs. A set of performance indicators to be included in the information requirements is also put forward.
