Fly Flat Project

This project sought to address the need for infill housing while achieving environmental, economic and social resilience. Through modular design and various energy performance packages, the project delivers net zero homes that meet Houston’s 50% – 80% Area Median Income.

Phius Alliance Houston

Houston is a world class city in many respects. We are home to the world’s largest medical center and rodeo, are the birthplace of NASA, and have the most diverse population in the nation. While diversity is likely our greatest asset, we are not known as a bastion of green building practices. Heat, humidity, and hurricanes are some of the greatest challenges we face on an ongoing basis. We are fortunate that Phius developed a climate-specific and cost-optimized standard appropriate for our cooling and drying needs. These buildings are comfortable, efficient, and more resilient to the natural disasters we Houstonians experience periodically. There is an incredible interest growing in our community to build Passive House projects. Thankfully, we have the tools and resources to do so.
