Somehow, the window of my room faces directly at the scorching beams of the sun all year long. The local weather here is humid, and the heat from the sun coming in from the windows makes the room almost unbearable to live in during mid-afternoons.
I could roll down the blinds, shut the windows and turn up the fans, but the heat still gets radiated through the walls into the room. And rolling down the blinds and closing the windows make the room dark and stuffy. The heat is really bad, so bad that often, low-quality rubbery textured materials in my room could sometimes feel sticky, like they were turning molten under the influence of the intense room temperature.
What are some techniques people use in their rooms to shade windows from scotching sunlight and to keep the room temperature cool without turning on an air-conditional the whole day?
