Heat pump clothes dryers are an exciting, relatively new electrification technology. One can cut perhaps 10% of your household energy use.

Abandoning gas for all-electric appliances? The electrical panel is the unsung hero of any home electrification project.

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.

Electrifying our homes, lives, and businesses is one of the most effective strategies to wean ourselves off fossil fuels, as we add more renewable energy to the electric grid. But do we have the capacity to produce, transport, and use the increase in renewable electricity that will result? Spoiler alert — the answer is yes – if.

The dark side of solar power includes trashing millions of used solar panels and batteries in landfills, intermittent production, and taking large tracts of land out of productive use. But new recycling approaches, and energy management and land use strategies are keeping the light on solar. It has a bright future.

Tracking the growth of zero energy homes in all their different forms is essential to building momentum for the growth of zero. If you are an owner, builder, or designer of a zero home, be sure your home is listed and help grow the movement toward zero.

Zero energy homes have many advanced features and systems. After you have your very own zero energy home, you’ll want to keep it operating at peak efficiency. Fortunately, home maintenance for these homes is not more difficult or time consuming than for conventional homes.  

You can’t build or remodel a home on the path to zero without buying suitable materials and equipment. That’s why the Zero Energy Project offers a select list of product ideas that can smooth your path to zero. Check out the new products that have been recently added to the Zero Energy Product Directory!

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.

Super airtight construction and heat recovery ventilation are necessary companions for zero energy homes. But the outside air may not be as clean as we think. Increasingly common extreme pollution events can overwhelm most fresh air systems. It’s time to make high-efficiency filtration a standard feature of zero homes.

Transparency is one cornerstone of a free market. Today, the real estate market is failing to provide homebuyers with the information they need to make sound purchasing decisions. At the same time, sellers are failing to realize the full value of their homes. One essential solution is to make energy disclosures readily available and to include them in a national database of green and energy-efficient homes.
