"comfort is 70% linked to the temperature of the walls"
I know I am arriving a little late but in case the author is still present on the site ... I try:
Is this a "hot figure" like "I'm 300% more cautious than average" or is it based on verified facts?
THANK YOU

It is a complex effect which also depends on how you heat with your feelings of T temperature, your feet, your ears, your cheeks, hot air blower, small very hot radiators or heated floor, poorly insulated walls with drafts coming from walls, windows, not insulated floor, etc ... in rooms with big difference of T according to the places of the rooms.
Floor cold on the ground cools your feet (except at jumping for hours in the air, an effective way to avoid being chilly by increasing your metabolism ) and even if the head is very warm with a high T you will have sure and certain discomfort !!
Same for the convection drafts stimulated by cold walls and windows which send back cold pulses, measurable by thermometers away from the radiators.
We can compensate a little with a radiator blowing on the feet and head in front of your desk or a radiator radiating by infrared on your head. !! without redoing any insulation in the house but with increased heat losses located around your body !!
Finally whenwe incubate a cold or flu we are much colder, chills, a day before, much more chilly, because the virus is manipulating you to lower your temperature and grow much faster the colder your body !!!
For me the only solution then is intense sport, run uphill quickly, even a single floor 66 times, to heat and stimulate me by circulating my blood throughout my body and boost my immune system a lot more by multiplying my metabolism under stress by 10 , and it's very effective !!

Hi BEOTIAN
I have personally verified that 65% humidity is the comfort limit!
Result!!!!!!!!!!!!!!!!!!
1. "No need to heat a room to 25 °" the discomfort will persist if the humidity is above 65%
2. "No need to cool a room to 28 °" the discomfort will persist if the humidity is above 65%
Treating humidity is cheaper than heat treatment

This is discussed! Example that I have in mind: dehumidification is the solution used in municipal swimming pools ... but it is also possible to do without dehumidification by maintaining the T ° of air 2 ° C to that of water. In this case, the water will evaporate more
It is possible in modern very well insulated swimming pools ...
At the level of the overall assessment I think that this solution is not uninteresting but very little used!
In any case, a swimming pool is an energy sinkhole!

hi Christophe
The only effective delta at 2 ° that I know of, is that of the "dew point"!
and therefore a delta below 2 ° will avoid condensation
and also a health problem,
without major effect on evaporation.
It is therefore possible to produce a dehumidifier "without energy" with a delta of 2 ° and more,
which makes it available in 3 seasons

At home, there is too much moisture in the house. (The poor over 120 years )
With 21 degree in the house, one has the sensation of being cold.
We want to turn the poel wood warms you so entrails.
I wonder if the humidity decrease with any device ?, would be the solution.
My father was a simple device, which in diquait comfort level depending on the temperature and humidity.
There was no batteries, but a ??? of hair which according to the growing or stretched moisture, and had an action on the indicator needle.
So I want to buy a device that dries the air; but I do not know which
It would be cheaper than burning wood, but Nuclear
Hi fair
A distinction must be made between humidity (humidity) and condensation.
The air is always humid even in a dessert,
but my cellar is dry with no mold or rust for an 80% humidity!
What is unhealthy is condensation
which leads to fungal infections with spores, difficult to manage.
so this is imperative
whether in a cold room, a swimming pool, a cellar or cellar and home
How to manage condensation?
By the dew point,
or minus 2 ° difference between air and wall (as for the weather)!
In approximate but economical theory. Huh!
So much for the catamaran
Home dehumidifier
If we cool a metal plate with outside air to 6 ° or 10 ° (at night in spring autumn and... Winter?),
we should get free indoor air condensation, without cooling system
So much for comfort
Simulation like at home!
stick a polystyrene sheet against a window tonight
leave a gap to let the indoor air pass,
the next day condensation will appear, see ice if it has frozen (behind double glazing huh? and 15 ° inside)
Easy? no!
Au revoir

Table of saturated vapor pressure of water:
Read that it takes 0.0234 bars to boil water at 20 ° C.
