Tillamook Row

Tillamook Row, a zero-energy community in Portland, Oregon, includes five buildings — a mix of owner and renter units with front porches and balconies oriented around a central courtyard. All five buildings were designed using Passive House Standards and modeling to meet Zero Energy goals, meaning the buildings will produce all or more of their energy needs from an 82-kilowatt solar array. 

Passive House standards at their core require airtightness to reduce energy requirements. To achieve this, the project team used Majvest, Wigluv and Rissan to create the airtight building envelope. 

A 2,000-square-foot common house is open to all tenants to use as a place to share meals, exercise and host gatherings. It can also serve as a community shelter during the case of a power outage.
