I went through a process of building an energy-efficient house, with double paned windows, thermo-resistant window frames, aerated concrete blocks, roof insulation and what not. This came at a significant surplus in my region, where 99% of the construction comes without it, and I got outer space looks all the time.
According to my calculations, the return on investment on reduced electricity costs will come in about 100-200 years, if not more.
In the meantime, if my house will end up in the market, it would hardly sell for any premium over any other house of similar footage in that area, so it's unlikely I would ever recover these costs.
