100% Ambient Heated & Cooled Home in Colorado - Passive Solar + Passive House | with M. Keith Sharp

Exploring Keith Sharp’s Ambient Heated and Cooled Home in Pagosa Springs, CO Join me as I dive into the incredible work of Keith Sharp, a mechanical engineer and emeritus professor from the University of Louisville. In this video, we explore the remarkable home he masterminded in Pagosa Springs, Colorado. With a deep understanding of physics, Keith has designed a self-sufficient home that achieves 100% ambient heating and cooling, with indoor comfort maintained almost entirely through passive solar heating and nighttime ventilation. It requires a fireplace for only a few days each year. Keith’s modern approach builds on the principles of historic passive solar design but prioritizes reduced envelope losses, smaller south-facing windows, and less thermal mass. This not only lowers embodied carbon but also improves cost efficiency. This home exemplifies what’s possible when data-driven design meets sustainable innovation. By tracking energy performance and carbon footprint, Keith's design goes beyond Passive House and Net-Zero Standards, creating a resilient, high-performance home that harnesses nature’s gifts. It stays comfortable year-round, even in extreme weather conditions, without mechanical heating or cooling systems.
