Mark O. Hatfield Building One Step Closer to Passivhaus

6.13.12 by the Green Hammer Team

The first stage of a deep-energy renovation of the Mark O. Hatfield building was recently completed. Green Hammer provided Passivhaus energy consultation to the project through a collaborative Multifamily Passivhaus Feasibility Study which included Central City Concern, Walsh Construction, SERA Architects and PAE Consulting Engineers. The building, located at the corner of Burnside and Broadway in downtown Portland, was built in 1910 and recent deterioration of the concrete fa ade posed a safety hazard to pedestrians. Ben Gates, of CCC, took advantage of the opportunity to not only complete necessary structural upgrades, but also begin a phased installation of deep-energy efficiency upgrades aimed at eventually reaching the Passivhaus energy standard. Reaching this lofty goal would make it among the first multifamily Passivhaus buildings in the country and one of the most energy efficient. By radically reducing utility costs for the building, CCC hopes to preserve a positive cash flow for its affordable housing even as energy costs rise.

Green Hammer helped the team by providing energy modeling services and identifying key measures for the most cost-effective upgrades. Phase I, which included the replacement of the existing single-pane windows with triple-pane units, was recently completed and celebrated with a re-opening ceremony and building tour. We were proud to see the building in its new glory and hear from current tenants about how much more comfortable the building is both thermally and acoustically.
