Can someone smarter than me figure out if this is more efficient than mechanical ventilation using a HRV/ERV? I looked at the paper the article references, but I didn't understand the comparisons between various ventilation approaches.
Just as old temperature maintenance was done via "no moving parts" (mainly large thermal masses), so old ventilation was done via "temperature drafting". For a long time we've overcome temperature maintenance via just forced air induction heating/cooling, which is not the most efficient. We're now saving some heat by using HRV/ERV but there's likely ways we can utilize things like this is talking about to reduce the energy needed to do it.
