Recovery Ventilation as an IAQ and Energy Efficiency Improvement
If you’ve heard about the ERV term but just started to consider it as an option for your home or business, then your first questions are: what does it mean? And what it does?
How ERV system works?
ERV unit injects fresh, clean air in the most efficient energy way available. The static plate core inside the ERV separates exhaust and new air streams and transfers temperature and humidity between the two air streams.
The fresh, cold outside air is humidified in the winter, preheated by the outgoing, warm interior air.
In the summer, the fresh warm, humid outside air is precooled and dehumidified by the outgoing air-conditioned interior air.
It also moves indoor odors and pollutants out of homes while keeping fresh, clean air inside.
Energy Recovery Ventilator Benefits
An ERV may be what you need to improve the air quality in your home or an office building.
- Energy Efficiency
- Air Quality
- Remove possible respiratory disease triggers
- If connected to any smart home system, manages work efficiency only during the pic hours, saving your money
How Green Ductors proceeds with ERV
The typical steps description the company does are:
If your ducts, HVAC unit filters, dryer vents, and chimney are clean, but the air seems still stale, the problem is more profound than what can be seen from first sight. Despite the cleanliness of these components, indoor air quality issues can persist due to the phenomenon of duct encapsulation. As buildings became more energy-efficient, they also became more airtight, which increases the potential for poor indoor environmental quality.
That is the reason why we recommend you set QAM (Air Quality Monitor). We do not represent a particular air monitor brand, so we are not trying to sell but to show the importance of setting the device (you can either use our service or fix it yourself).
Nowadays, those are connected to your phone or pad, making it easy for everyone to scan and locate the problem.
As soon as the QAM shows the results, the technicians will know for sure what requires fixing.
The main reason to set an ERV system is to lower the amounts of CO2 and VOC to the norm, which in general overcomes it by five times.
With the ERV working correctly, you will benefit from your indoor air pollution lower level, and energy bills will also show a decrease.
INDOOR AIR QUALITY IS A MAJOR PROBLEM OF XXI CENTURY
We spend 90% of our time indoors and 90% of the cost of a building are the occupants, yet indoor environmental quality and its impact on health and productivity are often an afterthought

People who work in well-ventilated offices with below-average levels of indoor pollutants and carbon dioxide (CO2) have significantly higher cognitive functioning scores—in crucial areas such as responding to a crisis or developing strategy—than those who work in offices with typical levels, according to a new study
Chan School of Public Health’s Center for Health and the Global Environment, SUNY Upstate Medical University, and Syracuse University.
NUMEROUS IAQ STUDIES
As you can see from the quotes above, maintaining the Indoor Air Quality might only seem like a secondary task. If not following the refreshing properly, it will affect your family’s well-being. All at once in multiple directions: anywhere you did spend your 90% indoors today or yesterday, or a month ago, more in an office or educational buildings when the concentration of CO2 rises higher due to a high density of people breathing in the room without proper ventilation or less at home.
Simple steps, such as described here, will help lower the pollution index, but professional service is still highly recommended if you want to live in a healthy environment.
