Central heating
The end result is a building which looks strikingly modern, but which has significant usability problems. Because the design features visible movement of people, the environment is noisy and the full-height glass walls to offices and study spaces offers little in the way of privacy, A large number of rooms have no direct external windows, relying instead on borrowed light from the central atrium. The subsequent lack of ventilation and reliance on fluorescent lighting for the whole of the day is not conducive to good health. Outside of rooms, all spaces are designed for transit and thus there are no informal 'social' areas for people to gather and talk. On a more mundane level, there are no kitchen areas and the only taps delivering drinking water are situated in the toilets. None of the toilets have external windows, and thus are usually less than pleasant spaces to visit. Central heating is under-specified which, when coupled with the already mentioned windows and ventilation issues, leaves the building cold in Winter and unbearably hot in Summer.
