CHICAGO, May 15, 2023 /PRNewswire-PRWeb/ -- Today, Phius, celebrated the annual Solar Decathlon Build Challenge winners who serve as visionaries for reshaping and creating more equitable, healthy communities. Phius is the smartest path to a zero-carbon environment, maintaining a locally tailored, globally applicable passive building standard that accounts for certifying the vast majority of all passive projects in North America. Finalists and winning projects in the Solar Decathlon often incorporate Phius certification principles to reduce energy demand and consumption and optimize for adaptability and resilience. This year's Build Challenge Overall 1st Place Winner featured a project from Ball State University in Muncie, Indiana, named The Alley House, which used Phius principles for passive building. Led by Cardinal Studio, The Alley House addresses gentrification pressure, promotes neighborhood revitalization, and facilitates lifestyle growth for local families. The finished building infills a vacant lot with an affordable two-family, net-positive energy home that activates public alleys, and integrates sustainable landscape design criteria and Phius passive house principles. This prototype building design showcases energy efficiency, offers community engagement opportunities, and creates a desirable, safe, functional, and healthy home to sustain two families while supporting sustainability and affordable living. A previous Design Challenge winner, SunBlock, in Tucson, Arizona, turns saved energy into stored energy, combining Phius passive building standards, solar PV, heat pumps, and thermal energy storage to provide affordable, fail-safe cooling to a low-income community. SunBlock understands that different buildings have different energy needs at different times. Schools need air conditioning during the day, but schools are out in the summer, meaning cooling equipment sits unused — exactly when homes most need cooling in the afternoon and evening. SunBlock generates carbon-neutral thermal energy and shares it with the neighborhood for an affordable cooling solution - helping the environment and delivering savings on energy bills to those who need it most.
