At least 20 energy efficiency programs in the U.S. and Canada are focusing on encouraging and assisting building projects to be built to zero-energy and zero-energy-ready standards.
According to the American Council for an Energy Efficient Economy (ACEEE), these programs have an annual budget of about $65 million. They have collectively completed nearly 200 single-family homes, about 900 apartments in multifamily buildings, and 74 commercial totaling more than two million square feet of floor area. Affordable housing accounts for a significant portion of the multifamily projects.
A zero-energy building produces an amount of onsite energy (typically from photovoltaic panels) that equals or exceeds the energy it buys from utilities plus the energy losses from generation and transmission over the course of a year. Zero-energy-ready buildings are typically efficient enough to be operated with onsite energy, but lacking the solar energy systems needed to make the building truly zero-energy.
A few programs promote zero-carbon buildings, which emit no net carbon over the course of a year. Zero-energy homes and buildings often cost a little more to build than conventional homes and buildings, but as experience is gained, costs are going down, ACEEE says.

NIST investigation of Champlain Towers South collapse indicates no sinkhole
Investigators from the National Institute of Standards and Technology (NIST) say they have found no evidence of underground voids on the site of the Champlain Towers South collapse, according to a new NIST report. The team of investigators have studied the site’s subsurface conditions to determine if sinkholes or excessive settling of the pile foundations might have caused the collapse.
