A requirement that has become unavoidable in today’s new homes
In Longueuil, where residential construction is booming, expectations regarding indoor air quality, energy efficiency, and compliance with HVAC standards have never been higher. For property developers, architects, and homeowners building a new house, installing a high-performance air exchanger is no longer just a bonus — it has become a functional and regulatory necessity.
At AirGreen, we support dozens of residential projects each year in Longueuil by integrating mechanical ventilation systems (HRV or ERV) into new builds, whether Novoclimat certified or designed according to the latest Quebec Building Code standards.
The air exchanger: at the heart of a modern and efficient HVAC system
New homes are designed to be airtight to maximize energy efficiency. While this tightness is beneficial, it makes air renewal absolutely essential. Without a high-quality air exchanger, indoor air quickly becomes stale, humid, and saturated with CO₂ and volatile organic compounds (VOCs).
The key roles of a high-performance air exchanger:
-
Maintain a stable humidity level throughout the house
-
Remove contaminants generated by cooking, building materials, and cleaning products
-
Provide consistent air quality without needing to open windows in winter
-
Prevent mold, odors, and respiratory problems
Real example: Installation of a Venmar EVO5 ERV in Longueuil
One of our clients, a young couple building their home in Greenfield Park, wanted to ensure their HVAC system met Novoclimat standards and provided optimal year-round comfort.
Project details:
-
1,950 sq. ft. single-family home
-
Installation of a Venmar EVO5 700 HRV ECM
-
Full integration with a Lennox central heat pump
-
Zoned ventilation for bedrooms, living room, powder room, and basement
Challenges encountered:
-
Client required extremely low noise levels
-
Needed to integrate a smart control system to modulate airflow based on occupancy
AirGreen solutions:
-
Installation with acoustically insulated rigid ductwork
-
Manual air balancing for system calibration
-
Integration with a smart thermostat communicating directly with the ERV
Results:
-
Indoor air measured with CO₂ levels below 650 ppm
-
Winter humidity maintained between 35% and 45%
-
Novoclimat certification obtained with no conditions
Why builders can no longer ignore this requirement
Building codes and homebuyer expectations now impose strict HVAC standards:
-
Novoclimat, LEED, and Rénoclimat programs all require high-performance ventilation systems
-
Municipalities, including Longueuil, are ramping up inspections for system compliance
-
Buyers are looking for homes that offer filtered, dehumidified, and balanced air
Risks of using low-end or poorly installed air exchangers
-
Loss of the home’s overall energy efficiency
-
Cold spots or condensation in certain rooms
-
Ongoing discomfort and post-sale complaints
-
Certification failures (Novoclimat, municipal inspections)
