Wind catcher

Tall, chimney-like towers rise from centuries-old adobe houses in Iran's desert city of Yazd, drawing in a pleasant breeze for residents of one of the hottest cities on earth.

This post is about wind catchers, a traditional architectural way to maintain air temperature low inside buildings commonly seen in the middle eastern countries. This is an awesome example of the creative talents that our ancestors have had.

Passive cooling systems are a type of building design that uses natural processes to cool a building without the use of mechanical systems.

This diagram shows how a wind catcher creates positive pressure on the windward side and negative pressure on the leeward side and how in doing so cool fresh air is pulled in and circulates the hot stale air out, it does a good job showing this by being very simple to read and shows just the basics of how the process works

Some of the best disguised air conditioning units we've seen, there are some great ways to hide or cover up your ugly aircon units

87% of all U.S. homes are equipped with air conditioners, and air conditioning accounts for 12% of residential energy use. Besides the fossil fuels that power them, many use refrigerants to cool the air, which can be potent greenhouse gasses if released. Is this the solution?

From ancient Egypt to the Persian Empire, an ingenious method of catching the breeze kept people cool for millennia. Now, it could come to our aid once again.

Natural ventilation systems rely on pressure differences to move fresh air through buildings - pressure differences can be caused by wind or the buoyancy effect created by temperature differences or differences in humidity. In either case, the size and placement of openings in the building is critical - useful to think of a natural ventilation system as a circuit, with equal consideration given to supply and exhaust. Wind causes a positive pressure on the windward side and a negative…

One of the main reasons for global warming is the burning of fossil fuels, natural gas, coal, etc which produces large amounts of greenhouse gases.....
