Building science experts, architects, engineers, and builders from across the U.S., Canada, and Europe gathered in early August in Westford, Massachusetts, for the 19th annual Westford Building Science Symposium, a conference sometimes known as “Summer Camp.”
Over three lively days filled with education, networking, and drinking, experts gave ten presentations on a variety of building science topics.

GBA readers who attended the conference had a sense of déjÃ vu at three of the presentations, since the talks covered topics that GBA has reported on in depth:
- Marty Houston from Walsh Construction discussed the Orchards at Orenco development in Oregon, a project that has been the focus of a multi-part series of articles on GBA that began in November 2014.
- Florian Antretter gave a presentation on hygric buffering research performed at the Fraunhofer Institute of Building Physics in Germany; my article reporting on that research was published in June 2015.
- David Boyer and Tom Schneider gave a presentation on the air leakiness of OSB. According to conference host Joseph Lstiburek, my December 2014 article on the topic was the inspiration for Boyer and Schneider’s recent presentation.

Ventilating high-rise apartment buildings
Lorne Ricketts, a building science engineer at RDH Building Engineering in Vancouver, British Columbia, gave a presentation on research into ventilation systems in a high-rise multifamily building. (Ricketts and his co-author, John Straube, also reported their findings in a paper titled “Corridor Pressurization System Performance in Multi-Unit Residential Buildings.”)
For multifamily buildings, mechanical engineers often specify a type of supply ventilation system called a “corridor pressurization” (or “pressurized corridor”) system.
Ricketts explained, “A pressurized corridor ventilation…
