Live LAB Events

Learning About Building Science (LAB) Events begin as live (and often lively!) monthly events hosted by RDH Building Science Laboratories. LAB Events are training and networking opportunities intended for architects, engineers, and anyone interested in building science. They are interactive and casual – our goal is to take high-quality research and building science principles and make them fun!

We hold LAB Events at our laboratory in Waterloo, Ontario, and webcast them live for those outside the local area. You can find the links to register below. Recordings of popular and important presentations can be found in our on-demand LAB Events courses. If you’ve attended a recent LAB Event and are looking for the slides, a link will be sent by email.

Details about continuing education credits are available on event registration pages.

February 20 – HVAC and Whole-Building Performance

Building scientists are often stereotyped as enclosure experts – and they are. But the best building science goes beyond the enclosure to take a whole-building perspective on energy efficiency, buildability, and durability. That means thinking about HVAC: buildings should be designed as a system, with interactions between the enclosure and the mechanical system accounted for. This is straightforward when you look at a single snapshot in time with no variability, weather, or humans involved. In the real world, it can get complicated. Join us for a closer look at the building science of HVAC systems and what happens when that science is not well understood or applied. We’ll discuss both commercial and residential buildings, with a focus on cold and mixed climate zones.

In-person only (Waterloo, Ontario), 5:30-7:30pm EST:

March 20 – A New Slant on Attics

Recent trends in residential roof design include modern flat roofs and classic mansard designs. Ventilating these low-sloped roofs can be tricky and one wrong step in design or construction can lead to significant moisture problems. Join Trevor Trainor and Jonathan Smegal to learn more!
