Terwilliger Plaza Passive House - April Chapter Meeting

  • Hip Chicks Do WIne 4510 Southeast 23rd Avenue Portland, OR, 97202 United States (map)

Terwilliger Plaza, founded around 1960 is a non-profit resident owned and governed senior living facility with approximately 350 current residents occupying 3 existing buildings.  Terwilliger Plaza provides Senior Independent living, Assisted living and licensed care.  The Parkview project will add 127 independent living units and amenities for all residents to the campus. Parkview is a new full city block, 326,000 sf all electric 10 story high rise building with underground parking connected to campus via a sky bridge.  And it is pursuing Passive House Institute US (Phius) certification. 

April’s presentation will focus on how Phius certification influenced decision-making on the Parkview project, from the architect to the owner, to the consultants and the contractors.  We will discuss strategies for achieving the air tightness requirements stipulated by Phius, while also mitigating condensation risk.  And revisit the discussions the design team and ownership teams went through in order understand what this process would entail.  We’ll also discuss how the team as a whole is ensuring construction activities support. Our presenters will include Peter Houseknecht of LRS, Dave Young of RDH, and Jake LaManna of Walsh Construction. We look forward to you joining us!

Learning Objectives:

  1. Describe air sealing approaches used in achieving passive house levels of air barrier performance.

  2. Discuss the coordination efforts between the design team, the ownership, and the contractors in executing detailing for a commercial passive house enclosure.

  3. Identify risks associated with designing and constructing air tight buildings, including energy losses due to thermal bridging and condensation risk.

  4. Plan quality assurance measures to track progress and verify performance of the mechanical systems and enclosure assemblies.

Speakers:

Jake LaManna, CSI, CDT, Associate AIA, Quality Manger, Walsh Construction

Jake LaManna, CSI, CDT, Associate AIA has been a Quality Manager with Walsh Construction Company for the last 7 years, and worked in architecture firms for several years prior, with a Masters of Architecture degree from University of Oregon.  With Portland CSI he has served in multiple roles including Secretary for 6 years, Board Director for 4 years, Learning & Libations Chair for 4 years, and participated in multiple committees during his last 9 years with CSI.  He also earned his CDT in 2014. For the Terwilliger project presentation, Jake will be describing the quality control activities Walsh has in place to ensure the project is built as the project was designed.  This includes testing to validate that the wall assemblies’ performance is as expected for passive house levels of air tightness.  More importantly, quality is managed through the collaboration of many team members to keep an eye on the consistent execution of details across the project, as well as an eye out for the unique details beyond the design that construction inevitably reveals.
