Nubes Ventilatica

Our 5-step plan

Research by HC Groep has produced a number of clear findings regarding airborne contaminants, their health effects and methods to eliminate or deactivate them. It has also become clear that no quick and cost-effective solutions are available to prevent the spread of viruses in buildings. However, it has become clear that the ventilation system plays a central role in supplying sufficient fresh outside air in buildings and preventing the spread of viruses, among other things.

The ventilation system is the focus of recommendations issued by various bodies to prevent the spread of viruses in buildings. Because this advice is very generic, building owners, managers and users lack action perspective; in other words, they don’t really know what to do. In addition, almost every building and its use is unique, this means that the (ventilation) solutions must be building- and user-specific. As a final point, comfort is often forgotten with all the attention paid to making the indoor climate safe; it is important to (continue to) pay attention to this as well.

NUBES VENTILATICA

We call this method: NUBES VENTILATICA and the plan includes the following 5 steps:

1. VENTILATE WITH FRESH OUTDOOR AIR
To ventilate, use as much fresh outdoor air as possible, remove (filter) contaminants from the outdoor air before it enters the building and recirculate as little “used air” as possible.

2. SUFFICIENT VENTILATION
Ventilate with sufficient fresh outdoor air to promote well-being and dilute contaminants and remove them with the return air. The air volumes specified in the Building Decree are insufficient; the recommendation is to use 50 to 60 m³/h of fresh air per person.

3. MONITOR AIR QUALITY
Monitoring, central filtering and cleaning outdoor air. Continuously monitor indoor air quality; in addition to temperature and relative humidity, measure CO₂, particulate matter, Ozone and VOCs. Taking corrective actions based on measured deviations.

4. APPLICTION SPECIFIC VENTILATION
Supply ventilation air with air distribution equipment (for example VAV units, air supply grilles, sensors, controls) specific to the function and use of the building (office, school, hospital, cinema, museum, laboratory, et cetera).

5. THE IMPORTANCE OF COMFORT
A safe indoor climate must also be a comfortable indoor climate. In addition to sufficient fresh air, it is important to properly regulate the other comfort parameters, being air temperature, air velocity, humidity, personal influence, lighting and noise.
