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 it means? 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 fresh air streams and transfers temperature and humidity between the two air streams.
In the winter the fresh cold outside air is preheated and humidified 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 just be what you need to improve the air quality in your home or in 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 common steps description the company does are:
If your ducts, HVAC unit filters, dryer vents, and a chimney are clean, but the air seems to be still stale, the problem is deeper than what can be seen from the first sight. 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 AQM (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 set it yourself).

Nowadays those are connected to your phone or pad, which makes it easy for everyone to scan and locate the problem.

As soon as the AQM shows the results, the technicians will know for sure what requires fixing.

Most of the time, the main reason to set an ERV system is to lower to the norm the amounts of CO2 and VOC, which in general overcomes it by 5 times.

Now with the ERV working properly, you will benefit with your indoor air pollution lower level and energy bills will also show the decrease.
What professors are saying:
Numerous IAQ studies are conducted at universities and research centers across the globe
INDOOR AIR QUALITY IS A MAJOR PROBLEM OF XXI CENTURY
"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 from the Harvard T.H. Chan School of Public Health's Center for Health and the Global Environment, SUNY Upstate Medical University, and Syracuse University.
"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," said Joseph Allen, assistant professor of exposure assessment science, director of the Healthy Buildings Program at the Harvard Center for Health and the Global Environment
As you can see from the quotes above, maintaining the Indoor Air Quality might only seem like a secondary task. In fact, if not following the refreshening properly it will affect your family 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 if you want to live in a healthy environment, professional service is still highly recommended.
