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.

People living in old apartment buildings often find themselves caught in a bind. They are stuck with high energy bills and have no reasonable path to make improvements. Here are measures that building owners can take to increase the value of their buildings while benefiting residents.

Good news! You can choose from more methods than ever before to reach the high levels of air tightness needed for zero energy construction. Many builders find it less expensive to seal the exterior structural sheathing. Here are six effective methods to consider.

When addressing indoor air quality, let’s not leave out existing homes and buildings. The same principles that make new zero energy buildings more healthy can also be applied to existing homes, whether during minor upgrades or major renovations. The return is in improved health and comfort. This is the final installment of our three-part series on indoor air quality and health.

To stay competitive, a production builder must find a good balance between cost, price, and profit. Here’s the story of one builder who has successfully added high-performance, clean energy features to their standard offering. More importantly this builder has developed an elegant solution to the challenge of solar-powered homes producing energy when it is not needed by the grid.

Imagine a world where a builder can set a precise level of building air tightness, pay one contractor to deliver it, and reach the same performance standard on every home. That world is here... today.
