TY - Technical report AU - Zachary Taylor PY - 2018 T1 - Residential heat recovery ventilation – technical brief PB - Pacific Northwest National Laboratory DO - https://doi.org/APO-218731 UR - https://apo.org.au/node/218731 AB - Heat recovery ventilators (HRVs) save energy by recovering heat that would otherwise be exhausted as part of energy code-mandated mechanical ventilation systems. Residential HRVs can be life cycle cost effective depending on equipment/installation costs and the severity of the climate. This brief evaluates HRV cost effectiveness in the context of building energy codes to identify the climate zones in which a code might reasonably require residential HRVs. ER -
