"The Biden administration announced Tuesday it will open applications for the first tranche of funding — $400 million — to help states and territories take up energy-efficient building codes.
A senior administration official told reporters Monday that under the codes, new buildings and major renovations would be done with better construction and in a way that is more efficient and resilient.
The Energy Department said in a press release announcing the funding that homes built using modern energy codes are 40 percent more efficient than homes built 15 years ago."
