I am completly opposed to Air-conditions propagandized as a solution to climate change. What is the wright approach to combating this state of temporary relief except from old-fashioned fans? Don’t get me wrong. They do the job for me. I am reffering to finding a solution for people more with health issues or large facilities that are in need of something more drastic.
That is kinda like earth tubes isn’t it? Which you could retrofit. More powerful cooling can be achieved by using the tubes as part of a geothermal heat pump. Bonus there is that its also even more efficient than a regular heat pump in winter too.
