I live in a house full of people, electronic equipment and other stuff pouring out energy in the form of heat. The sun beating down adds considerably to the problem. I have found that it is quite possible to reduce the build up of heat just by using blinds and curtains thoughtfully and timeously thereby making the house far more comfortable. Upon researching this further imagine my surprise when I discovered that humans have been using SHADE to do this since time began.
Whatever will they think of next.
