How much would something like that cost?

He claimed to have spent 80K euros on it 10 years ago. No idea what prices would be in the States. But I'm guessing that 80K figure is for the glass alone.

It looks great. 80k investment to go from 9 months of heating to 6 months. Expensive project, wonder if solar would have yielded more in the north.

Well I think it's as much about happiness as it is energy efficiency. They get to enjoy the outdoors year round.

I wonder how they control humidity inside the home and prevent mildew/mould? The air in the greenhouse would be very humid all year round I would have thought?

I think heat exchange air ventilation systems are quite common in Northern Europe. Presumably you could just keep the windows of the inner house closed most of the time, and then have a ventilation coming from outside through the heat exchanger.

This reminds me of an apartment complex I saw last year, also in Sweden (north of Stockholm, in Norrtälje). Hard to see inside, but it's practically tropical, with palm trees and flowering plants, and all doors of resident's apartments let out into the garden.

I've thought about building a house in a barn to save on heating/cooling (Texas, it's dadgum hot here). But this is much much cooler (or warmer, if you're in Sweden)!

You might like Matt Risinger's YouTube channel, https://www.youtube.com/user/MattRisinger . He's a builder in the Austin area who does very energy efficient homes. He uses (a variation of?) this thing called a "100-year wall" system, the gist of which is that the entire envelope of the house is sheathed and sealed, basically turning the frame of the house into "furniture," in that it's in a conditioned space. The big insight is that the vapor-barrier-on-the-inside scheme came about in climates that were mostly dry outside, and mostly moister inside, whereas large areas of Texas (and tropical and subtropical areas) are the reverse.

I wonder if this has a negative effect on the amount of fresh air that they get

I wonder how much fresh air they get from all the plants pumping oxygen out?

Plants produce oxygen when they grow, and you would need to grow about 8 pounds a day to supply oxygen for one human. See https://www.gardenmyths.com/houseplants-increase-oxygen-leve...
