We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

Hi everyone!
I've seen a lot of claims over the years of living walls or planted buffers that can mitigate *outdoor* air pollution and have always assumed there's no real scientific basis for that idea, unless we're talking an actual forest that's 10s of feet thick.

Crowdsourcing here to see if anyone has access to two LCA's that can be used to compare functionally equivalent consumer products: a fossil fuel powered to a battery one?  (A good product might be a car or stove, or a heating system with a boiler compared to a heat pump, perhaps?  Needs to include the B-use phase probably...)...
