For TC Legend Home’s 9th time, we are thrilled to announce another Department of Energy Housing Innovation Award (HIA) winning home!

House-in-a-Hollow has won the grand prize for the ‘Custom for Buyer less than 2500 Square Feet’ category. We could not have achieved this award without the amazing homeowners who helped us push the envelope and our extremely skilled field crew who nailed the execution (pun-intended). 🙂

Our very own Talia receiving TC Legend Home’s Department of Energy 2022 Housing Innovation Award!!
Talia had a blast at the EEBA conference last week in Scottsdale, AZ and loved seeing The House in the Hollow showcased!

Each year the HIA updates their application pushing companies to innovate more and change with the times, and this year was no exception.

Along with the house performance, design and materials/sustainability information required, the award also requires the builder to submit information on their business metrics and how they create quality construction.

This year, they added the “Advances Home Concepts” section which consists of written portions on the company’s advanced building practices, smart building techniques and environmental impact.

Much like the Seattle based Built Green program, they have also added a portion to evaluate the company’s sustainable business practices which includes their diversity, equity and inclusion practices, and workforce training.

These latter additions are very valuable as the industry recognizes the interconnection between sustainable housing and equitable housing. Sustainable housing should not just be for the wealthy and, in fact, those of lower incomes are far more likely to live in homes or areas that negatively impact their health.

This is due to the homes being less desirable to the wealthy and therefore cheaper, creating a market where the only homes that are financially available to folks with lower income, are the ones that are unhealthy. It should go without saying that this is unfair and unjust. Making it that much more important the sustainable housing be available for everyone.
