Just a thought.
Given that other viruses inactivate (die) faster at higher temperatures, what is the optimal temperature for air conditioning?
For offices in tropical Singapore for example, 22C-24C has been suggested as the optimal temperature range.
In Japan, they turn on air-conditioning only when the temperature reaches 28C.
But in many places air-conditioning is set for lower temperatures.
So it seems to me that a global reset of air conditioning temperatures would be beneficial as:
1. It means the higher ambient air temperatures kills viruses faster
2. It reduces air-conditioning electricity consumption. That reduces operating costs, helps save the environment, and reduces imports of coal and oil from a national security point of view.
Dehumidifying the air is more important than the temperature. In addition, modern office buildings always have the air conditioning in operation, because for security reasons you cannot open windows.
I read few article, it looks like the humidity/temperature range define the survival time of the viruses.
But this is not simple, the effective humidity level depends on the type of the virus.
Higher temperature killing the virus faster, but the humidity level that is most hostile for viruses is between 60-80%, depending on the type .
Keep the temperature as high as possible ,and the humidity as high as possible - on 23+ Celsius it is not that easy to keep high humidity level.
Interesting is, low humidity level actually keep the virus alive longer.
So , dry / cold air favourable for the spread of viruses.
