How effective is passive inlet ventilation?
I am the second owner of a house I have been retrofitting for a couple years, primarily for energy efficiency. The attic has been brought up to R65 with blown paper cellulose, the rim joists have been insulated with foam, etc. The insulation/weatherization upgrades have brought our house from approx .38 air changes per hour down to .23ach according to blower door tests. We have installed very efficient bath fans and wonder how effectively a product such as the Panasonic passive inlet vent will work in conjunction with the bath fans. The cost of a whole house HRV/ERV is more than we can afford at this point and we don't want to simply exhaust the air. Any thoughts on the passive inlet option? Much obliged.
