PHIUS, Universities Partner to Train Emerging Passive Professionals

A feverish buzz builds in Alison Kwok’s University of Oregon classroom as students scramble to
complete final details of architectural elevations, double-check load calculations, and precisely
label drawings.

This cohort of aspiring practitioners join a growing number of design students getting a jump start on their sustainable design careers by obtaining CPHC credentials while still enrolled at their institutions. To date, five institutions have formed partnerships with PHIUS to provide CPHC training: University of Oregon (OR), Miami University Ohio (OH), Prairie View A&M (TX), Ryerson University (ON), and Ball State University (IN). Most students who earn CPHC in school are practicing with firms within a year.

The CPHC curriculum and modules are largely the same as the weeklong trainings PHIUS regularly provides, with some important modifications. Professor Kwok sometimes opts to invite professionals as guest lecturers to cover content like WUFI modeling, while instructing on other items like assembly calculations of details herself (she is co-author of Passive House Details, with Donald Corner and Jan Fillnger). Other faculty instructors use the culminating product—developing a PHIUS+-compliant design—as more of a collaborative studio project than an individual take-home. This applied learning allows students to iterate through the design process while allowing collaboration, guidance, and peer exchange.

“They were motivated to learn the material again and were appreciative of getting into the depth that the PHIUS materials offered. The opportunity to become a Certified Passive House Consultant through a course tailored to their schedule was incredible!” said Professor Kwok.

These emerging professionals are already applying their building science knowledge and skills to great impact, while building portfolios and relationships with industry veterans.

The Race to Zero National Student Design Competition was one recent venue where the rising stars of sustainable design were able to really shine. This annual contest began with 84 teams from 68 institutions spanning eight countries, all vying for the best project in one of five categories: single family detached (suburban/urban), single family attached, small multifamily, and elementary school. The finalists were invited to NREL in Golden, Colorado this spring to present their projects before peers and distinguished judges (including PHIUS Executive Director Katrin Klingenberg).

Four of the finalist teams—Prairie View A&M, Miami University, and Virginia Tech—were led by students who had earned the CPHC credential through their university. Other teams, such as IIT, were supported and mentored by established CPHC professionals.

We’ll be featuring more stories from emerging CPHC professionals in the coming weeks. And be sure to join us in Boston for the 13 th Annual North American Passive House Conference, where Race to Zero winners will be presenting on their winning submissions.

PHIUS Joins US, EU Delegates to Tour Affordable Passive Buildings

On a sweltering hot and humid summer morning last week in Washington DC, PHIUS staff joined community development and design professionals from both sides of the Atlantic on a tour of sustainable social housing. The visit to Weinberg Commons, the first affordable multifamily retrofit project to earn PHIUS+ certification, capped the weeklong DC Energy Future Exchange Tour, organized by the Ecologic Institute.

The tour was led by Koray Aysin of HousingUP with Donna Rosano of Zavos Architecture + Design and Matt Fine, CPHC (formerly with Zavos). The guides described in detail the challenges and creative approaches they applied to renovate a dilapidated group of garden apartments into healthy, dignified, affordable homes for families of limited means—while also achieving ambitious energy and environmental targets. Because the developer, Housing Up, also pays the utilities, they had an incentive to invest in the building’s energy efficiency, knowing that the benefits would exceed the costs down the road. Some of the strategies the team used to hit stringent PHIUS+ energy targets included:

  • Specially designed window boxes that block solar heat gain while allowing natural light to enter the dwelling areas
  • Outboard insulation applied between vertical joist, a creative approach to a structural challenge

  • Energy recovery ventilation that reuses energy from indoors to pre-heat or cool thefresh air stream
  • Exceptional air tightness of 0.58ACH 50. This result is remarkable in new construction, and even more difficult to achieve in an existing building
  • A Variable Refrigerant Flow system that allows different sides of the building to heat and cool simultaneously. Due to superior insulation and air-tightness, all twelve units in the building are served by just one 2 ½ ton condensing unit—typical of a large single-family house.
  • Solar hot water panels and a basement storage tank; this results in a 40% cost savings
  • Rooftop solar electric panels developed by a third party, which sells back to the apartment at a rate 50% lower than grid purchase

 

Attendees were also able to see passive performance in action. While the tour started on a hot, loud street, discussion continued in the cool and quiet of the community room, thanks to the well-executed features. Here, participants learned about the financial aspects of the project. Financing sources included federal Low Income Housing Tax Credits, local housing funds from DC DHCD, funds from the DC Department of Behavioral Health, and philanthropic support.
