I am not opposed to updated codes for building.
New construction homes are much better insulated, better windows and doors than houses built previous to 1980.
The house I built in 1990 is still a better built structure than the two other houses I bought since then. These two other houses were both built in 1972.
Double pane Low E glass windows. Fiberglass or steel skinned foam insulated doors. R50 in the attic. House wrap. These are all changes to building codes instituted to save energy and MONEY. My electricity bill is over $200/month from Eversource in NH. It is not getting cheaper. I have done everything I can think of to lower the energy consumption of my house.
So, some of these regulations are not all bad.
When nj institutes more regulations they don’t have the best interests of others in mind. They either enrich the corrupt mandarins that run this state or expand the power of it, or both.
I know a builder who wisely gave up using the word Green. He builds High-Performance houses.
I read somewhere that more new building materials have been introduced in the last decade than is all of human history. Many of those are designed to increase performance.
But, that should be at the choice of the builder or buyer, not some government hack (who can be paid off to only allow certain brands)
