Airthinx saves Hospital $50k in 2 days

The complex hospital environment requires special attention to ensure healthy indoor air quality (IAQ) to protect patients and healthcare workers against hospital acquired infections and occupational diseases.

As with any other building, it is packed with complex equipment and systems such as energy management and HVAC systems. System performance directly impacts maintenance frequency, equipment life, and energy usage. Types of HVACS include Variable Air Volume & Fan Coil Systems, both adopted by new and old buildings.

In an environmental ecosystem, if one of the components fails, it affects the building as a whole. When looking at environmental data, it is important to see the big picture. If a few of the parameters are slightly off, collectively these parameters can create an unhealthy or even dangerous environment.

For example, high levels of CO2 are a proxy for poor ventilation and movement of air in a space. Inadequate building ventilation systems account for 53% or hazards to indoor air quality resulting from lack of outside air, poor air distribution, temperature & humidity, and containment sources inside the system

LCI Engineering Australia recently shared an experience with their client, a healthcare facility, after measuring indoor air quality with the Airthinx IAQ Device for just 2 days, they were able to identify the source of pollution and eliminate the need for costly remediation.

“A healthcare client of ours approached us with an overheating problem in their Radiotherapy Planning Room that was part of a VAV air conditioning system with a dedicated VAV unit serving the Room. The client suspected they would need to replace their AC system. We attended the site and our inspection confirmed the room was in fact warm (25C) and conditions were stuffy. We installed the Airthinx IAQ device. After two days, we noticed an odd pattern in the logged data. The temperature was steady at 25C +-0.5C, regardless of time of day and the room use. The CO2 was swinging wildly, peaking at 2000 ppm, confirming the feeling of stale air when we initially visited the site. With this new information, we reviewed the original system design which indicated that the VAV unit should be more than capable of providing enough fresh air to control the build-up of CO2. We contacted the Facility Management department and provided the new air quality data. They reviewed the BMS logs for the Room and also sent a technician to check the VAV box. The technician found a broken drive linkage on the VAV box. The VAV box was then fixed. We were able to see the change in the room conditions within 10 mins of the VAV box being fixed, and were able to rule out the overload in the room as a source of air pollution. The room is now controlled at 22C, and CO2 remains steady at 600 ppm. The radio therapists are very happy, and the client has not spent $50,000 on a new AC system to control the air quality conditions in the room.”

Airthinx is revolutionizing the Indoor Air industry with a low-cost professional air quality device, providing accurate & precise monitoring at room level of 9 indoor air pollutants (Particulate Matter 1.0, 2.5 and 10 microns in size, Carbon Dioxide, Formaldehyde, Volatile Organic Compounds, Temperature, Pressure & Humidity). It’s simple to install, works directly out of the box, and has built-in 3G and wifi, so it is always connected to the cloud and collecting data. For the first time, Environmental Health & Safety personnel can have access to data anytime, anywhere from the web, iPad or phone, so they are best equipped to make real-time decisions in any infrastructure.
