The PHIUS (Passive House Institute US) model seeks to greatly reduce the amount of energy consumed by the building sector. PHIUS promotes a cost-effective model that attains stringent sustainability standards through high-insulation, airtight building and high-performance windows. This leads to minimal mechanical systems and a net-zero building model.
As a CPHC (Certified Passive House Consultant), I have employed this type of model through my university teaching as well as in practice. I strive to build the recognition of this building standard- that is proven through building science and energy modeling- as the current California/ Pacific Regional Representative for PHIUS.
