ERV Post Follow Up

Earlier this spring we posted an article on Pre-certified Passive Components: ERV or energy recovery ventilators. The “fresh air machine” of passive homes, including those built by EkoBuilt, ERVs are a vital component and worthy of close inspection. The unit we recommend is the Jablotron Futura Passive ERV and it’s pre-certified by the IPHA.

We fielded a couple of great questions following that post and want to answer them here:

Whole home ventilation: ERV and HRV explained

We recently came across a great, highly informative article on whole home ventilation for anyone looking at building a new home. Six Steps to Success With Heat-Recovery Ventilation by Bruce Sullivan was first published on the Green Building Advisor blog.

The article explains the difference between HRV/ERV and the necessity for highly efficient fresh air machines. At EkoBuilt, we prefer ERV (energy recovery ventilators) over HRV (heat recovery ventilators) because modern buildings should not only be airtight but also vapour tight.

It is extremely important for long term building health to make sure there is no condensation within a wall cavity. An ERV in a vapour tight house is able to maintain comfortable humidity inside the building while removing excess moisture (anything above 60% humidity). These machines also offer a constant fresh air supply for a healthy interior environment.
