Canada's housing crisis demands better buildings — here are the changes that could improve apartment and condo life
The Conversation — Canada needs more housing, but it also needs better quality housing. Simple design changes can fix common complaints about apartment and condo living.

Summary

"Canada's housing crisis demands better buildings — here are the changes that could improve apartment and condo life" — Marianne Touchie, The Conversation (May 24, 2023)

The article identifies common performance issues in multi-unit residential buildings (MURBs) and presents evidence-based design solutions that improve comfort, health, and energy efficiency.

The problem

Multi-unit housing can be more sustainable than detached homes, but in practice MURBs suffer from:

Design solutions

Ventilation: Central pressurized corridor systems are unreliable. Better alternatives include central direct-ducted systems or, ideally, suite-based heat/energy recovery ventilators (HRVs/ERVs).

Air sealing: The leakiest walls are those separating corridors from suites. Developers should focus air-sealing efforts there, along with sealing stairwell doors and adding elevator vestibules.

Soundproofing: Airborne noise is partly addressed by compartmentalization. Impact noise requires acoustic underlay below finished floors. Outdoor noise is reduced by airtight exterior walls and smaller windows.

Thermal comfort: Large, poor-quality windows are a major driver of discomfort. Smaller windows with low U-values, exterior shading, and in-suite heat pumps (rather than central systems) provide better year-round temperature control.

The good news

Many of these solutions have multiple benefits: they improve resident comfort, save energy, and reduce environmental impact. Heat pumps can replace carbon-intensive natural gas heating. The article calls on residents and building owners to advocate for these design changes through developers and provincial building codes.
