The ‘3 for 2 Concept’ allows the construction of three floors within the standard space of two floors, without any impact on perceived floor-to-ceiling heights, which researchers say could reduce energy consumption in offices by 40 per cent.

The methodology, devised by the Future Cities Laboratory (FCL) of the Singapore-ETH Centre (SEC), a joint Swiss-Singaporean research centre, is being…
