Air-to-Air Heat Exchangers for Healthier Energy-Efficient Homes
I have an ambition to live in an insulated metal barn. They’re incredibly cheap compared to regular construction. I would then construct smaller dwelling units inside of it, non load bearing, which could be played around with much like legos. (It may help to know I’m the designer of the hexayurt, a shelter technology popular at Burning Man and eventually bound for the world’s refugee camps.)<p>Key to this plan is handling humidity. Metal buildings don’t breathe. Humidity condenses on the metal, turns into mould, then you have real problems.<p>But with humidity sensors and A2A heat exchangers you wind up with the best of both worlds. I think.<p>Let’s say I’m not going to be building this before I’ve had real analysis from a good hvac engineer or two.<p><a href="https://www.kitbuildings.com/products/insulated-steel-buildings" rel="nofollow">https://www.kitbuildings.com/products/insulated-steel-buildi...</a> For a sense of prices.
