I moved into one of these buildings about 1.5 years ago and it’s indeed awesome. We also have no gas and tons of solar panels on the roof so last year with the insane energy prices in the whole of Europe I spend €2,83 for all my energy including heating for 8 months, and I’m easily cold so I always have the heating on. The only problem is as you say to get rid of heat in summer, but they opted for smaller windows than is standard so less heat is getting in in the first place. And because of the great insulation you also have pretty much no traffic noise from outside. The only complaint I have is that the mechanical ventilation can get quite loud when it’s windy outside, but the benefits are so overwhelming I can’t be that bothered by it.
