Just found something on the net that might be interesting for those who are going to build a house. It?s a cooling system that should make a room +/- 8?C cooler than normal. It has been developed by a Dutch cooperation named ?12 ambachten?. It works as follows a metal chimney is painted black and around it a (plexi-)glass shell is placed that is sealed hermetically. The sun heats the air in the chimney and this rising colon of air pulls out air from the room. Which is replaced by air that comes from 15 m long 200 mm tubes put at a depth of more than 60 cm and ending in a inspection pit. According to what I?ve read you?ll need 1 such tube for every 20m?.
