Passive cooling

Passive cooling is technology that cools buildings without using power. It generally means the building doesn't use pumps or fans. Instead, other techniques are used to keep sun heat out and cold air in. Like orientating a building to take advantage of winter sun and avoid direct sunlight in the summer.

I am closer to a nerd than cool, but there are certain moments when I could be considered cool by some people. And I never use pumps or fans.
