Install a high efficiency ventilation system.

Crop projet-1

As houses become increasingly airtight for the sake of energy efficiency, they also accumulate pollutants and humidity indoors, which increases the need for mechanical ventilation systems to reduce major health impacts. But mechanical ventilation that brings in cool air and evacuates hot air will generate a net energy loss during heating season. The solution is to install a high efficiency system that can recover that energy and produce fewer GHGs.

Our recommendations :

  1. Install an effective vent hood to evacuate excess humidity and odours from the home and improve the air quality. Your best bet is to choose an ENERGY STAR® model, as these are much quieter and consume up to 65% less energy than regular models. There is no need to choose a vent hood with a capacity of more than 300 cubic feet a minute (150 L/s).
  2. The air outlet for the vent hood should always be outside the home, so the humidity, gas and other contaminants are completely evacuated from the living area. If this option is not possible, choose a vent hood with a HEPA filter and follow the manufacturer’s maintenance and filter replacement instructions.
