ERV

Can an ERV reduce indoor CO₂ levels?

2026-10-10

An ERV can help reduce indoor carbon dioxide (CO₂) concentrations by replacing CO₂-rich indoor air with outdoor air, provided that the outdoor airflow and air distribution are adequate for the occupancy.

How much fresh air does a home need?

2026-10-10

Required outdoor airflow depends on the applicable building code, occupancy, floor area, room use, and the ventilation design standard used for the project.

Is an ERV suitable for hot and humid climates?

2026-10-10

An ERV can be part of a ventilation strategy for hot and humid climates, but the design must account for both heat and moisture loads.

Does an ERV work in both summer and winter?

2026-10-10

Yes. An appropriately designed ERV can operate in both heating and cooling seasons.

Can an ERV control indoor humidity?

2026-10-10

An ERV with an enthalpy exchange core can transfer moisture between incoming and outgoing air streams. This may help moderate indoor humidity, but it does not actively remove moisture in the same way as a dedicated dehumidifier.

Does an ERV save energy?

2026-10-10

An ERV can reduce the energy required to condition outdoor ventilation air by recovering part of the heat and, where applicable, moisture from the exhaust air.

What is the difference between an ERV and a standard exhaust fan?

2026-10-10

A standard exhaust fan removes indoor air but does not normally recover energy from it. Replacement outdoor air must enter through designed inlets or other openings, and its temperature and moisture can add to the building's heating or cooling load.

What is the difference between an ERV and an HRV?

2026-10-10

An HRV (Heat Recovery Ventilator) primarily transfers sensible heat between incoming and outgoing air. An ERV (Energy Recovery Ventilator) can transfer sensible heat and moisture when equipped with an enthalpy exchange core.

How does an ERV system work

2026-10-10

An ERV draws outdoor air into the building and exhausts stale indoor air through separate air passages. Inside the energy recovery core, heat and moisture can transfer between the two air streams without intentionally mixing the bulk air streams.

What is an Energy Recovery Ventilator (ERV)?

2026-10-10

An Energy Recovery Ventilator (ERV) is a mechanical ventilation system that supplies outdoor air and exhausts stale indoor air while transferring heat and, in enthalpy recovery systems, moisture between the two air streams.
