Performance criteria and some important target values for residential mechanical ventilation systems with heat recovery (VS/HR) are reported and subsequently applied to four audit cases. For each audit case, a characterization of the building, its energy performance, and VS/HR, as well as the scope and main results of the audit, are given. Finally, a table with a selection of these performance criteria and the corresponding audit values of the four cases demonstrates that this criteria list serves as a valuable tool to compare and evaluate different VS/HR.
