Air conditioning accounts for approximately seventy percent of the elec - tricity used in new commercial office buildings in India; therefore the most effective way to reduce electrical consumption is to reduce the cooling load and to use efficient cooling systems. T h e v er t i c a li t y o f t h e co u r t y a r d i s a cc e n t u a t e d by t h e t a l l t r i c k l e f o un - t a in , t h e n a rr o w d i v i d e b e t w ee n t h e b uil d in g ’s w in g s , a n d t h e s k y a bo v e .

The most efficient air-conditioning chillers are water- cooled units in which the evaporation of water transfers heat into the atmosphere. These are suitable for large central systems, but unsuitable for this building, which is designed for decentralized operation and con trol. Another drawback of these systems is that they consume substantial amounts of soft water. Air-cooled systems on the market offer the benefit of modularity but they are inefficient during high summer. Lall thought it worthwhile to investigate a fundamental alternative – a hybrid system that could offer the best of both worlds. In the hot dry season the system would use direct and indirect evaporative cooling, and in the humid season refrigerant cooling. No such unit existed on the Indian market, so Lall worked with air-conditioning consultants to develop a prototype. The specialists configured the system and sized the compo- nents , and Lall’s office arranged the components into a compact physical unit, housed to suit the architecture.

In the DA building, U-shaped concrete columns house the vertical ducts.
