Hospital saves 50,000 € in 2 days

The complex hospital environment requires special attention to healthy indoor air quality (IAQ) to protect patients and health professionals against hospital and occupational diseases.

As with any other building, it is full of complex equipment and systems such as power management and HVAC systems. System performance directly affects the maintenance frequency, equipment life and energy consumption. Types of HVACS include Variable Air Volume & amp; Fan Coil Systems, both acquired by new and old buildings.

If one of the components in an ecosystem fails in the environment, this will affect the building as a whole. When viewing environmental data it is important to see the big picture. If some of the parameters are slightly different, these parameters can create an unhealthy or even dangerous environment together.

For example, high levels of CO2 are a proxy for poor ventilation and air movement in a room. Inadequate building ventilation systems account for 53% or indoor air quality dangers due to lack of outside air, poor air distribution, temperature and humidity and containment in the system

A health care organization, after having measured the air quality of the indoor air with the IAQ device for only 2 days, could identify the source of pollution and make the need for expensive remediation superfluous.

“A healthcare client approached us with a problem of overheating in their Radiotherapy Planning Room, which was part of a VAV air conditioning system with a special VAV unit that operates the Room. The customer suspected that they had to replace their AC system. We visited the site and our inspection confirmed that the room was in fact hot (25 ° C) and that the conditions were stuffy. We have installed the IAQ device. After two days we saw a strange pattern in the recorded data. The temperature was stable at 25C + -0.5C, regardless of the time of day and the use of space. The CO2 swayed wildly, with a peak of 2000 ppm, confirming the sense of stale air when we first visited the site. With this new information, we looked at the original system design, which indicated that the VAV unit had to provide more than enough fresh air to control the build-up of CO2. We contacted the Facility Management department and supplied the new air quality data. They have reviewed the BMS logs for the room and also sent a technician to check the VAV box. The technician found a broken disk connection on the VAV box. The VAV box was then repaired. We could see the change in the space conditions within 10 minutes after the VAV box was repaired and could exclude the overload in the room as a source of air pollution. ”

No remediation needed, saving 50,000 € in two days.
