Multi-unit residential buildings (MURBs) represent a significant and growing proportion of housing in North America. Traditionally, ventilation air is provided by a central corridor air supply system and is distributed among the suites through entry door undercuts. This system, although being used for decades, has proven to be neither effective nor efficient from an energy or indoor air quality perspective. In this seminar results from a study on the impact of using individual in-suite Energy Recovery Ventilators (ERV) and Integrated Fan Coils (IFC) with energy recovery in high-rise residential buildings are investigated and compared to traditional centralized make-up air systems.
