I was wondering about this the other day. In NL, insulation has been part of the building code for ages. With stronger requirements every decade or so. Insulated windows have been required since the 80ies for new houses. Now it’s triple pane krypton glass. Is this not the case for the USA.
- opencl 7y agoThe US has insulation requirements, it varies a lot state to state but new housing generally has at least decent-ish insulation. The main issue is that there is a lot of very old housing stock in the US. As of 2015 the median house was 37 years old and 40% were over 45 years old. In the area I live the vast majority of the houses were built in the 40s or 50s, though most people have done some amount of insulation retrofitting. http://eyeonhousing.org/2015/08/the-aging-housing-stock-2/ http://eyeonhousing.org/2015/08/the-aging-housing-stock-2/
