We know that decarbonization requires electrifiction, and we know that heat pumps work in many situations. But many people still wonder: Will heat pumps work in cold temperatures?

Building materials and equipment play a key role in the efficiency and affordability of zero energy buildings. This is why we’re proud to introduce the Zero Energy Project Product Directory to help builders identify appropriate products and to stimulate the supply chain to provide products that will draw the building sector toward greater energy efficiency.

When Amber Westerman Set Out to Build a Net-Zero House, She Knew the Design Had to be Small and Smart.

When choosing a high-performance wall assembly, you have many choices. One of them is to build double-stud walls. The double-stud wall approach sometimes raises the concern that it will lead to mold growth and wood rot. Is this fear based in reality? Green Building Advisor checked it out and found that wood-moisture content and seasonal temperature fluctuations do not seem to create moisture problems in double-stud walls.

Homeownership has been the core of the mythical American Dream, but it has been slow to take hold within the millennial generation. Perhaps the housing sector has not been meeting their needs for small, energy efficient, well connected homes. Well planned zero energy homes can make homeownership more accessible to millennials.

The future of residential construction will include more factory buildings. BrightBuilt Home builds modular homes that are modern, durable, and zero energy ready. The precision of factory construction is a perfect match for zero energy homes, and BrightBuilt has been building zero energy homes this way since 2010.

He may no longer be the world’s richest man, but he still has some big ideas about reducing greenhouse gases. Gates’ latest book describes an ambitious, well-thought-out, set of climate actions needed to get to zero by 2050. Building efficiency and electric vehicles are just the “easy” part. Here are highlights from his plan for what must be done and how to make it happen. It's a must read for all who want to help avoid a climate disaster.

Building or renovating a home? One key to success is hiring zero energy experienced construction professionals. Now you can find designers, builders, energy consultants, prefab companies and panel manufacturers that have already built to zero. Check out our new, expanded directory of zero energy construction professionals.

Two trends are now converging that will promote a zero energy lifestyle. First, electric vehicle sales are poised to grow dramatically. Second, positive energy homes are growing in popularity. These homes create enough energy to supply all at-home energy use and much of the transportation energy for households. It's time for building professionals to build positive energy homes for homebuyers who will soon be driving and charging electric vehicles.

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.

Baby boomers have enjoyed unprecedented financial opportunity, convenience, and economic security— benefits built largely from extraction and burning of fossil fuels. The resulting impact on Earth’s climate has created the Baby Boomer carbon debt. It’s time for them to take action to preserve the climate for future generations, but there’s not much time.
