Desert Skies Energy > Sustainable Design > Core House

Nationally Recognized Design

CORE House was a joint venture by the team at PHX Architecture / Cosan Studio alongside Desert Skies Energy. The design was part of the Sustainable Design Competition held by the City of Phoenix. The goal of the competition was to encourage the construction of ultra-low energy homes; the recognized designs would be those with the best potential for widespread adoption in the Phoenix area.

CORE House is a testament to exceptional design with the plans reaching Emerald certification (NGBS). In addition, the house is fully adaptable to ADA standards without changing the dimensional floor plan. Achieving a HERS 30 without solar was the result of meticulous attention to detail and creative design features such as extending the ICF wall system to the footer to serve as slab edge insulation.
