Its all very well using environmental energy sources to heat and cool a building, but very little attention is given over to clearing the air. Besides the pollutants from cleaning products and product breakdown, CO2 levels inside a building can have a stimulating effect on the body, which kind of destroys the purpose of a relaxation of a home.

The passive house standard requires mechnical ventilation using heat exchangers to minimize energy loss. http://tepperarchitects.com/?p=522

I'm in the middle of building a PassivHaus. The building itself is mostly done and we're working on the interior. There are still a few gaps that haven't been plugged and the heat exchangers have not yet been installed. I'm above 800m elevation, snowstorms every weekend. It's cold here. My house also actually faces West instead of South, so I'm not getting much heat from the sun. This was a surprise to use because the previous house on the same site had the same orientation and was scorching during the evenings, it's amazing what a pair of Low-E triple paned windows can do.

Despite all that, the builders manage to work inside the building with a single kerosene stove[0]. And the building stays comfortable for several hours even after the stove has been turned off.

I watched a report on a block of "passive houses" in Germany and the people liked it, but had a complaint that the air is too dry, so they dried their laundry indoors. I'm a fan of the idea, so not really critical, but I wonder what it's really like to live in one.

Sounds great. Do you have a blog or anything online about your project?

I'm looking into making a house sustainable right now and the windows are actually a point of contention. One side thinks super-high insulated (triple pane) windows are a waste of money, the other swears by them. Assuming the frame doesn't leak, does triple really make that much of a difference?

They should also look at the Skytherm Roof which can both heat and cool a building passively. See https://www.architectmagazine.com/technology/harold-hay-skyt...

I don't see anything about heating a building?

It’s vaguely in the article. Says in the winter the process is reversed
