Bottom-up Air conditioning:

Simple steps in shading and orienting the building have been followed with sophisticated air conditioning design. An extreme low-energy, hybrid AV system (VAV, or variable air volume type with cooling by chilled water) has been used here. Ducts travel through the hollow under the false floor and throw cold air up rather than down. this creates a mushroom cloud of cold air within the habitable

heights of the room rather than cooling all the volume, which allows for higher floor heights (helping daylight enter). By investing in this quality design and plant, the AC demand has been brought down by half than normal (to 32m²/tonne).
