Occasionally some (generous(?)) condo ads will include a マンション環境性能表示 with things like 建物の断熱性: 2 stars
I tried doing some research on it and 2 stars seems to mean that a place is insulated within certain margins set by regulation, but this means absolutely nothing to me. Where can I find details on exactly what to expect from 1, 2, and 3 stars for the various criteria of マンション環境性能表示?
