Projects
The project brief did not include any formal green star rating . Good practice energy efficiency strategies were however implemented and includes items such as heat recovery capabilities of the 4 pipe Heat pump chiller , economy cooling on all AHUs , variable water and air flow systems and supply air temperature reset based on the Variable Air Volume diffuser feedback .
Various building elements such as high-performance double-glazed facades and low energy light fittings were selected based on simulations done in thermal modelling software to promote energy efficiency and thermal comfort in the building .
UNIQUE ELEMENTS The simultaneous heating and cooling capability combined with the thermal storage is a fairly new concept and makes the system unique in a sense . The system as a whole is not unconventional , but the building shape made the implementation of the system challenging and one of a kind . RACA
