The building systems of the new Headquarters have been developed in conjunction with Atelier Ten to minimise both the energy required for cooling and the need for potable water consumption. In milder months, the façade is operable to allow natural ventilation – minimising the need to provide cooling to the building. When conditioning is required, it will be optimised for energy conservation via the use of ventilation energy recovery – allowing fresh air into the spaces with reduced energy impact, and the waste heat that would normally be rejected from the chillers into the atmosphere is to be harvested to provide free pre-heating of the domestic hot water supplies.
