The building has achieved 45% energy saving compared to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standard baseline and consumes minimal portable water with the use of a tube well and a pump powered by solar energy, the harvesting of rainwater, and the installation of efficient sanitary fittings.
Furthermore, in adherence to the Bank’s green agenda, the mechanically ventilated areas of the building are fitted withenergy-efficient air conditioners and the carbon dioxide levels of office area are continuously measured to maintain a healthy indoor environment for its occupants.
