Heat Recovery Ventilator (HRV)

HRV Commissioning & Balancing

Did You Know?

Many HRV's Being Installed Today Are Not Balanced

HRV systems are designed to supply fresh air to bedrooms and exhaust stale humidity from bathrooms. Without having the airflow of the appliance measured, rooms may not be receiving sufficient fresh air.

Industry Professionals Know

Many of the HRV's Installed Today Are Poorly Performing
This might mean that a bedroom isn’t getting any fresh air. It might also mean that the building is supplying air at a higher rate than it is exhausting air, putting a positive pressure on the building.

​But don’t just take our word for it. This process is so important that the City of Vancouver plans on making HRV balancing and commissioning mandatory in 2021.

​Whether you contract Our Energy or another company, ensure that your HRV systems are properly operating.

What We Offer

Our Energy has a formalized balancing and commissioning process for HRV systems. We measure the HRV to ensure it is supplying and exhausting balanced and sufficient air. Next, we measure each grille to ensure the proper ventilation is getting to the proper areas.

What You Get

We leave you with a signed and stamped document that lists the measured rates of airflow in the building. This is your confirmation that the HRV system is doing what it was designed to do.

Expertise

Our Energy director, Christopher Dawe, developed HRV design, installation, and commissioning & balancing protocols for a provincial not-for-profit organization. He serves as the chairman of the HRV committee and offers training around the province for industry professionals.

Why Are HRV's Such a Hot Topic?

The Heat Recovery Ventilator (HRV) is the Fresh-Air Machine

An HRV simultaneously provides fresh air to the occupants, and exhausts stale air, moisture and pollutants. An HRV system that is improperly designed, installed, or commissioned means insufficient fresh air to occupants, and / or pollutants and moisture not being exhausted.

The Heat Recovery Ventilator (HRV) is a Balanced Ventilation Appliance

What does this mean?
An HRV supplies and and exhausts air, simultaneously. And if the appliance is functioning properly, the supply and exhaust airflow rate will be the same.

If they are not the same, this will either pressurize or depressurize the building.

This causes many problems, including deterioration of the building structure from moisture buildup, reduced efficiency of the appliance, pollutants being pushed into the structure of the building instead of being exhausted, increased risk of hazardous soil gases, and increased risk of gas equipment back-drafting.
