The question is about how we can find solutions that make our world better without exhausting our resources.

Thank You
@Harimi Djamila thank you for your answer, I agree with you.
Kind regards
Firstly: let's try to clarify what is thermal comfort. Comfort is an attempt of equilibrium of temperature and moisture of the body with the surrounding environment. Having said that, such a type of comfort cannot be a mechanical system with a rigid management.Through milenium people found ways of approaching comfort, some almost naked as in Africa; others with a very thin and ample blouse to ventilate the body underneth the tissue such as in Paquistan, etc.etc. Many with very accssible to the air movement (Japan, Guiane).
Comfort is a feeling of equilíbrium at the surface of the body between the body temperature at the skin level and the temperature of the surrounding environment (on the shade), Yet the equilibrium can be disturbed because of the humidity of the air which interferes with the phenomena of evapotranspiration at the skin level.
Air conditioning emerged with the double purpose of cooling an drying the air and subsidiary clean the air. It would be more sain if the intervention of the air conditioning would stated for mild/intermediate values instead of ambitioning to reach 'the point' of comfort leaving people to keep their routine of adjusting their comfort with clothing,, eventual slightly different form that to be used if ther was not climatization.... Real important is the cleaning of the air, and that has nothing with air conditioning as we see it nowadays. This, is particulary useful in case of great aglomerations of people. A large church in Portugal (Fatima) has s blowing air bottom up to compensate for the sweating of the pellerins just arrived....
It would be more wise if the intervention of the air conditioning would stated for mild/intermediate values leaving people to keep their routine of adjusting their comfort with clothing instead of ambitioning to reach 'the point' of comfort that eventual would satisfy everybody. Like rabbits.... Real important is the cleaning of the air, and that has nothing to do with air conditioning as we see it nowadays. This, is particulary useful in case of great aglomerations of people. A large church in Portugal (Fatima) has s blowing air bottom up ('displacement') to compensate for the sweating of the pelegrins just arrived.... And a moderate temperature and humidity control of the space for 9000 people.
Sorry, I was too long.
The intention was good. One cannot say the same of the ideas above.
At least, I hope, we don't see AC as a panacea. I am a mechanical engineering. I taught thousands of students. I have no problem of conscience with that...

Thank you so much for your answer, and believe me I agree with you about AC.
Best regards
Thanks you very much for your kind reply. The problem, My Friend, is that in the 'so called' developed countries/áreas of the World the technological approach overwelms all environmental reasonning and is focused on the use of strict mechanical devices for blowing, heating or cooling. That alienates the meaning of Environment, the relationship of the user with the environment of proximity and with the outdoor environment and seems to alienate the importance of thermal insulation and also the thermal mass of the walls, the orientation, and location of openings, namely windows, etc. We have to respect the importance of thermal mass.,shadding, and thermal insulation and proper ventilation.
Well let's keep in touch.
