Feldman Architecture and Positive Energy Forge a Path to World Class Architecture 
Feldman Architecture and Positive Energy Forge a Path to World Class Architecture 

Feldman Architecture is a distinguished firm based in San Francisco and widely recognized for their creation of warm, light-filled spaces characterized by an understated modern aesthetic. Beyond the visual appeal of their designs, Feldman Architecture is driven by a profound commitment to addressing complex problems through design, aiming to significantly enhance human interaction with the built environment and the planet. This ethos finds a powerful complement in our work here at Positive Energy. We are a specialty MEP engineering and building science firm from Austin, TX, and share with our partners at Feldman Architecture a foundational mission to transform the delivery of conditioned space to society.

The Theresa Passive House: A Blueprint for High-Performance Design in Hot-Humid Climates
The Theresa Passive House: A Blueprint for High-Performance Design in Hot-Humid Climates

The Theresa Passive House, nestled in Austin's historic Clarksville neighborhood, stands as a remarkable example of how architectural preservation can harmoniously merge with modern sustainable design. This 2100 square foot residence, completed in 2020, is not merely a renovation and addition to a 1914 Craftsman bungalow; it is a meticulously engineered dwelling that embodies rigorous targets in energy efficiency, indoor air quality (IAQ), thermal comfort, embodied carbon, and responsible materials sourcing.[1] These ambitious goals were established by the Passive House Institute U.S. (Phius), a leading authority in high-performance building standards.
