net zero homes

According to Harvard’s Joint Center for Housing Studies, there will be around a million-and-a-half housing units built in the United States this year (unit includes apartments, condos, and single-family houses). Most of these units will be built to the standard of the applicable building codes. That sounds like a good thing, but remember that the code is a minimum standard, so a house that simply meets code requirements is the worst house you can legally build.
