Understanding Montréal’s New Residential Ventilation Standards: An Essential Guide by AirGreen
The City of Montréal is preparing to implement new, stricter regulations regarding residential ventilation. These major changes, driven by the desire to improve indoor air quality, will directly impact owners of houses, condos, and multi-unit residential buildings. At AirGreen, we closely monitor these regulatory developments to consistently provide our clients with compliant and optimized air exchanger (HRV/ERV) solutions. Here is everything you need to know to effectively prepare for these new requirements.
Why is Montréal Strengthening Residential Ventilation Standards?
Protecting Residents’ Health
Poor indoor air quality is now recognized as a major health risk factor, causing respiratory problems, chronic allergies, and even exacerbating conditions such as asthma. In Montréal, where homes are often airtight to better manage extreme weather conditions, proper ventilation becomes crucial to maintaining a healthy environment.
Reducing Humidity-Related Risks
Excessive humidity in homes, very common in neighborhoods such as Rosemont, Plateau-Mont-Royal, and Ville-Marie, causes mold growth and structural damage to buildings. The new regulations aim to ensure better humidity control through mandatory air exchangers in certain types of housing.
What Exactly Will These New Requirements Be in Montréal?
Mandatory Mechanical Ventilation
The main change is the mandatory installation of a mechanical ventilation system with heat or energy recovery (HRV or ERV) in all new residential constructions and during major renovations. This rule will uniformly apply to Montréal, Laval, Longueuil, as well as municipalities on the North Shore and South Shore that often follow Montréal’s lead.
Stricter Standards for Installed Devices
Devices will now have to meet strict criteria:
-
Mandatory Energy Star certification
-
Minimum heat recovery capacity set at 65%
-
Precise airflow requirements based on dwelling size
At AirGreen, we already prioritize models such as the Lifebreath RNC155 MAX or the Venmar AVS E15 ECM, which fully meet these new regulatory standards.
Mandatory Regular Inspections
To ensure these installations remain effective over time, Montréal will now require periodic mandatory inspections of residential ventilation systems, ensuring adequate maintenance for maximum energy efficiency and air quality.
What These Changes Mean for Montréal Homeowners
A Profitable Initial Investment
Indeed, the mandatory installation of an air exchanger represents an additional initial cost. However, in the long run, it generates significant savings on energy costs thanks to efficient heat or energy recovery. In Montréal, AirGreen regularly observes heating bill reductions of up to 30% among its clients.
Increased Indoor Comfort
Compliance with these new standards guarantees superior indoor air quality, controlled humidity, and an overall more comfortable environment for residents. Our clients from diverse neighborhoods like Ahuntsic, Verdun, or Pointe-aux-Trembles regularly report immediate improvements in their daily comfort.
