Choosing between an HRV and an ERV

...Energy recovery from exhaust air is becoming common place in cold regions, and two types of equipment can do this - an HRV (Heat Recovery Ventilation) and an ERV (Energy Recovery Ventilation.) Both HRVs and ERVs are somewhat new to mainstream home construction, and can often be confused. In an effort to clear that up...

...energy efficiency. The ratio between the energy consumed during the operation of a building and its embodied energy is affected not only by how energy efficient it is, but also by how long the building will stand. In other words, the downside of some high performance homes is that they can require more embodied energ...
