The Roof
The building’s utility plant sits in the side halls of the roof, not on the open deck — waste processing, cooling, a fuel cell, water treatment, and data infrastructure, mirrored on the east and west sides. Between them, the open deck carries the tennis and pickleball courts. Every bath/entry unit, every lift, and the foyer at each end reach the roof the same way they reach every floor below. The plant capacities shown are drawn as the system is expected to stand in about five years, not as it would be purchased today.
Keeping the plant in the side halls leaves the middle of the roof open, so the deck is given to sport rather than machinery. The equipment in those halls is measured bay by bay on The Plant, Measured, and how its power and cooling work is explained on Energy & Power and Cooling. The whole building is described on The Public Building.
