Yesterday I was at one workshop on Green buildings and once again felt that the field of passive cooling is driven by sentiments rather than science. Especially passive techniques such as earth air tunnels, where underground pipes are used for cooling/heating ambient air before feeding into the building, significance of key design issues such as diameter, spacing between pipes, flow velocity are less known. Whereas, if not chosen properly they can simply not permit the tunnel to work inefficiently and make it a monument rather than a functional passive cooling system.
I am worried about this issue is simply because such examples create wrong notion about the concept not being useful/successful whereas there is nothing wrong about the concept and its utility.
