Building occupants in Vietnam can breathe a better air quality thanks to ENVIRA and Seven Nine collaboration

Indoor air quality, Success stories,

A WHO research found out that over 60,000 deaths in Vietnam each year are linked to air pollution, about six times the number who die in traffic accidents on the country’s notoriously dangerous roads. If we keep in mind outdoor air quality affects indoor air quality, it is necessary to implement a real-time indoor air quality monitoring system that improves living quality for the community. From now on, building occupants in Vietnam can breathe better air quality thanks to ENVIRA and Seven Nine collaboration.

Indoor air quality in Vietnam matters  

In Vietnam, there are a lot of industrial zones with high concentrations of workers, like government factories or textile manufacturers with thousands of people working in a very small space. If workers spend indoors about 90 percent of the time and indoor air is proven to be 2 – 5 times more polluted than outdoor air, indoor air quality solutions are necessary to ensure occupants well-being, like Nanoenvi IAQ. Nine Seven became ENVIRA’s partner in Vietnam for the distribution of this IoT device that monitors indoor air quality. 

How indoor air quality is monitored 

Nanoenvi IAQ devices monitor the following parameters. 

  • Carbon dioxide (CO2). 
  • Carbon monoxide (CO).
  • PM10 and PM2.5 particles.
  • Volatile organic compounds (VOCs).
  • Relative Humidity (RH).
  • Temperature.
  • Atmospheric pressure. 

Based on them, the device calculates an air quality index (AQI) that monitors the level of health and well-being in indoor spaces. Users will be able to know the quality of the air they breathe through color codes. 

The possible values of the index move in the range 0-7, where: 

  • 7 optimum quality (blue LEDs). 
  • 4-6 good quality (green LEDs). 
  • 2-3 moderate quality (yellow LEDs).
  • 0-1 poor quality (red LEDs). 

The importance of IAQ  

Poor indoor air quality can produce, among other effects:  

  • Low productivity.   
  • Increase in absenteeism.
  • Increase in operating costs.
  • Chronic health problems like respiratory diseases or heart diseases. 

So, why it is important to monitor indoor air quality?  

  • It can be noticed an improvement of the work environment for employees and improvement of the interior environment for customers and users.
  •  It can be implemented improvements in ventilation and air renewal strategy.
  • There is a reduction of the feeling of a “stuffy atmosphere”.
  •  Decreased risk of spreading disease or infection by air.
  •  Increased productivity and performance at the work level.
  •  Guarantee of a safe and healthy environment. 

Good IAQ helps prevent COVID 

The COVID 19 pandemic has changed the world forever. Now people spend more time indoors, so indoor air quality has become a concern among the population. Researchers have found that there is a close relationship between air quality and coronavirus. Also, in this context, the public concern about the ventilation of closed spaces has increased. Monitoring of CO2 levels allows obtaining a key indicator to know the social distance and the ventilation rate. In a building where the Nanoenvi IAQ is installed, if the device begins to show inadequate air quality, the building manager can take measures to renew the air, such as opening windows or activating the air conditioning. 

From now on, building owners in Vietnam who wish to monitor indoor air quality can contact Seven Nine. Its alliance with ENVIRA makes it a leading IAQ device distributor company in the country. The header picture shows the first installation of Seven Nine in an office in Vietnam.
