The office generates both moisture and pollutants. This moisture comes from cooking, washing and breathing. At excessive levels, moisture condenses on windows and can cause structural deterioration. Areas of excessive moisture are breeding grounds for mould, mildew, fungi, dust mites and bacteria. You know you have a problem if you notice black spots on walls. These unsightly spots indicate mildew growth. Mould spores and dust easily become airborne and circulate freely throughout the office, possibly causing a range of symptoms and allergic reactions.
For a better solution to office air quality whilst retaining the heat during colder months is to install an energy-recovery ventilator (ERV). Heat from the outgoing stale air warms up the incoming fresh air. A typical unit features two fans – one to take out office air and the other to bring in the fresh air. What makes an ERV unique is the heat-exchange core. The core transfers heat from the outgoing stream to the incoming stream in the same way that the radiator in your car transfers heat from the engine’s coolant to the outside air. It’s composed of a series of narrow alternating passages through which incoming and outgoing airstreams flow. As the streams move through, heat is transferred from the warm side of each passage to the cold, the air streams never mix.
Depending on the model, ERVs can recover 85% of the heat in the outgoing airstream, making ventilators a lot easier on your budget than opening a few windows. ERV contains filters that keep particulates such as pollen or dust from entering the office.

Increase ventilation rates and energy recovery to improve indoor air quality and reduce the cost of conditioning larger amounts of outdoor air.
