Summer is in full power here in Kerala, India. Concrete radiating heat and rooms are hot even at night.
Have seen people mention things like blackout curtains, reflective or white paint on the roof etc.
Have upped hydration and am now sleeping with windows open, with a mat on the floor.
What all things do the people in your locality do? Or if you have any specific insight into cost-effective techniques or so, could you kindly share them?
Thanks in advance
You can dig a tunnel that is at least 6ft down and 100ft long that leads into your home at one end and up to a narrow opening on the surface on the otherside. Then add a fan that blows air from the tunnel into the home. This will function as a natural AC unit. It is a lot of work to accomplish but can cheaply cool a home as long as its maintained.
The science behind it is that the temperature under the earth past 6ft is around 55 - 65 degrees Fahrenheit depending on your region of the world. The fan will then draw the air through the tunnel where its cooled and pushed into the home. The tunnel doesn’t have to be that big just like 2ft in diameter. Though mold can grow here so you would want to use a material that is resistant like a smooth walled plastic pipe for your tunnel.
I’m not sure how prevalent it is around the world, but in my area, I think this sounds like a great way to get radon poisoning. The concept for pumping cool air into a space is good though.
