Did you know that modern ventilation is a major spreader of viruses?

Comment: There have been deaths in Norway during the epidemic. However, the healthcare system is kneeling in the world’s richest country. The community is closed and a lot of infection spreads in poorly ventilated rooms.

Our underfunded hospitals contrast sharply with the overfunded government oil sector. We are witnessing a declared crisis and a multilateral declaration of bankruptcy. The business model and strategy must be re-evaluated.

Many argue that unilateral efforts to stop the business should be replaced by modernizing the underfunded health care system. According to Nav, 4000-7000 nurses are needed at any given time. Their status and wage development are pent-up while employees of publicly owned oil companies earn three times higher average wages. The CEO of Equinor . served 50 times more From a highly qualified nurse. Everyone praises health workers, but politicians don’t take the cues, which my fellow UiS professors, Kruke and Engen, have demonstrated in SA’s history of emergency preparedness paradoxes.

As of this writing on December 16, there are “only” 371 CHD patients in Norway, of whom “only” 63 are on a ventilator. Hospitals in Oslo and Viken postponed 1,000 surgeries in the first two weeks of December. So far 1,204 people have died of Covid in Norway, but every year an average of 900 people die of influenza without a reaction from us. Now almost no one dies.

poorly ventilated rooms

In October 2020, the International Family Health Organization stated in the report «Indoor climate and risk of infection“The risk of infection appears to be higher in small, poorly ventilated rooms.” One year later in December 2021, the rhetoric in the British government document intensified.Ventilation during the coronavirus pandemic». Poor ventilation is highlighted as a more serious spreader of infection than expected. In Norway, this is deprecated.

Well-insulated modern buildings are windproof like thermos. Fresh air is necessary or we will suffocate. instead of people air shock Through the windows, the central fresh air inlet dominated the hissing and noise.

The film I, Paolo Sorrentinos, «God’s hand“(2021) an accident resulting from the bad indoor climate and lack of air. We are exposed to great risks in the internal environment. new scientific studies It shows that wood burning in homes contributes three times more to particulate air pollution in the UK than the transport sector, even though only 8% of the population fires using wood. It concluded that “new so-called ‘environmental design’ wood stoves should be sold with a health warning ‘because burning wood can triple the amount of harmful particulates in indoor air.'” In Norway, 1,700 people die prematurely each year due to by Pollution (PM 2.5).

Improper ventilation spreads viruses

Viruses are most commonly transmitted indoors. Ventilation is used improperly, and is often restricted to a minimum recirculated air for energy saving reasons. In the omicron outbreak at Louise’s restaurant in Oslo, nearly everyone in the room became infected, including those not at the Scatec group’s table. Viruses spread more easily in dry indoor climates. The less ventilation and the more electricity heated, the drier the indoor air becomes. So shock ventilation through windows is always good advice. Most of the year it does not cause heat loss and you can wear more than one T-shirt indoors.

It was built in Zurich Administartive building Without ventilation and heating system. Ventilation is done naturally through windows and the building has a large block of bricks so that the internal temperature is stable. Excess heat from people, computer equipment, lights, and machines suffice. Each person releases 100 watts of heat when we are sitting still. Ten people conduct heat like 1KW panel oven and preferably double when we move.

I painted myself compact housing Without space and central ventilation ducts. Instead, we used the block in the porcelain; honey tubes With a diameter of only 16 cm it is inserted into the wall of each room. A small, quiet fan removes and heats used room air passing through the porcelain. When the direction of the fan is reversed, fresh outside air is drawn in and heat follows that into the porcelain block. 60 meters of air ducts and 3 square meters of technical space are provided for each residence. In commercial buildings, 8 percent of the floor area is often used for vertical columns and technical rooms. When removing ductwork, you do not need lower ceilings and save 15% of the floor height.

Think Fresh of Ventilation!

The University of Cyprus uses natural ventilation without ventilation ducts. Large amounts of fresh outdoor air are drawn through the building and rise vertically. The float is stimulated by “solar chimneys” – which push the air up and out as in a chimney. Radiation from the direct sun or diffuse cloudy radiation heats the outside of the chimney and drives the process.

If we want to reduce the risk of spreading the virus, we must rethink but also revitalize old knowledge. This will be an epidemic not the last And we’ll also be sharing air between us in the future. Good ventilation is necessary so that the indoor climate does not become dangerous to health and fatal. As well as the World Health Organization and the European Agency for Infection Control (ECDC) now refers to this. We must all do what we can as long as politicians are unable to ensure adequate hospital preparedness for the population.

The importance of natural ventilation is underestimated and knowledge is forgotten. Technology has taken over the sheer area, volume and floor height that vent duct solutions are required. Noise, noise and costly maintenance are the result – and the spread of viruses.
