This shot of the burned-out Koolhaas-designed hotel in Beijing caught an interesting subject in the foreground: a hundred cooling towers on the roof of a neighbouring building. What do they do? They take the heat generated within the building by lighting, equipment and solar gain and pump it out into the atmosphere. Think of it as coal-fired exterior heating, just what you need in Beijing. Jonas Risen at Greenline notes:
Every action as a consequence. In this case you can witness the brutal nature of moving thousands of tons of BTUs from one system, the building interior, to another, the exterior environment, and vice versa. Entropy will have its revenge.
