Candice and Marco are concerned about their high humidity levels after a recent renovation and have called in the expert.
Ventilation
The technician in this video recommended the installation of an Energy (enthalpy) recovery ventilator), not to be confused with an HRV (Heat Recovery Ventilator) An ERV exchanges and uses the energy contained in the exhausted air to treat the incoming outdoor air. During the warmer seasons the system pre-cools and dehumidifies incoming air while humidifying and pre-heating in the winter. The ERV improves the indoor air quality while reducing the total HVAC equipment capacity. A heat recovery ventilator does not transfer moisture, only heat so it's more common in cold climates with lower cooling requirements in the summer.
In the video skit above the homeowner had just completed a kitchen addition and retrofit. Whenever the building envelope is improved ie. higher insulation and air sealing, there is the potential for less ventilation which could lead to combustion spillage and high indoor humidity rates. (Most building standards today require the installation of an HRV or ERV) Generally this conversation would be taking place before the renovation as opposed to after, but for entertainment purposes this worked for the skit.
