Spray foam is used enthusiastically by many builders hoping to improve energy performance of their projects. But the hidden climate impact of conventional 2-pound, closed- cell foam is actually a huge step backward. A new generation of low global warming potential spray foam corrects this fatal flaw.

The sixth annual inventory of zero energy homes has just been released. It shows considerable growth to almost 28,000 units. Projections indicate the number could double in 2021.

Brightleaf Homes used zero energy ready homes to break into the Chicago home building market. Building higher value high performance homes was just the beginning. Then they had to make the extra cost work for buyers. Here’s how they do it.

There is an elephant in the utility room. Clothes dryers have big energy appetites. As homes go all-electric, switching to heat pump technology for clothes drying will save energy and reduce carbon emissions, while reducing the wear and tear on your clothes.

Since before the dawn of civilization, humans have stayed comfortable by harnessing the forces of nature. These principles can also be applied in today’s homes and buildings to reduce or eliminate energy used for conventional air conditioning.

While health is always on the list of zero energy home benefits, it was the motivating force that prompted Steve Weise and Brenda Nunes to develop this 60-unit neighborhood in Central Washington. All homes in the development include a comprehensive package of proven features that protect health, maintain durability, and guarantee zero energy ready performance. But Steve and Brenda are taking the health of their homes to a higher level.

Ted L. Clifton of Zero Energy Plans has been designing and building zero energy homes using structural insulated panels (SIPs) for many years. He shares his thoughts about affordability, building codes, and electrification in this interview.

A good product meets real human needs. Abraham Maslow’s hierarchy of needs provides a powerful framework for converting those needs into effective messaging to homebuyers. To sell more zero energy homes, sellers need to link the needs of home buyers with the many tangible benefits of zero energy homes.

At current rates, most offices and homes will not be retrofitted for decades or even centuries to acceptable levels of energy efficiency. One approach is mandatory building performance standards—requiring existing buildings to meet a performance benchmark (energy or carbon intensity, performance rating, etc.), with owners having multiple years to bring buildings into compliance.

There is a special connection between homes and homebuyers. Yet many new homes are marketed like commodities. To effectively sell zero energy homes, it’s necessary to create a direct link between buyer needs and these homes’ intrinsic values.

A national marketing campaign to build awareness of zero energy homes is coming soon from Team Zero. Everyone in the zero energy value chain will see more demand and higher sales from this collaborative generic marketing effort. Check it out and join the movement.

Leading U.S. cities are filling a crucial information gap in the residential real estate market by requiring home energy disclosures for potential homebuyers: a much needed transparency measure and consumer protection practice. This process provides buyers with an energy efficiency rating on every property listed for sale. An online resource and a support network are available for local governments that want to adopt similar energy disclosure measures.
