Marker Time – Indoor Air Quality (Ventilation)

The second “Marker Time” video covers Indoor Air Quality in a bit more detail. Today we take a look at mechanical ventilation inside the very tight envelope of the 120K House. We cover both local (kitchen & bath) ventilation as well as whole house ventilation in the form of HRV’s (Heat Recovery Ventilator) and ERV’s (Energy Recovery Ventilator).
