Without any further treatment, it seems that waste heat is at least enough to heat living and office space (which is probably what they're doing with it). If you arrived at that 10% by just looking at the K, keep in mind that 0C is ambient temperature and already represents the lowest energy level of that system. I really believe it should be possible to take and use more of that 30° degree difference than a mere 3° off the top, even factoring in heat pumps for consolidating it and moving it around. 30° degrees of temperature difference is roughly the subcooling margin for nuclear reactors (http://en.wikipedia.org/wiki/Pressurized_water_reactor http://en.wikipedia.org/wiki/Pressurized_water_reactor), and that's at even higher overall temperatures!
