Positive Energy's Education and Advocacy Efforts

Our comprehensive approach to MEP engineering and building science consulting is deeply rooted in a strategic vision that extends far beyond individual project delivery. Our commitment to the idea of "Healthy people, healthy planet” is unwavering. It is not just a statement, but a guiding principle that permeates our extensive education and advocacy efforts. Through the firm’s Building Science Blog and The Building Science Podcast, we aim to actively cultivate knowledge everywhere we can, demystifying complex technical concepts like indoor air quality and intricate wall assembly dynamics for architects and the broader industry. This accessible knowledge transfer empowers architects to confidently integrate advanced building science into their designs, mitigating risks and ensuring the long-term performance and durability of their projects.

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.
