The office HVAC consisting of a mixed-mode design with openable façade elements allowing for natural ventilation and cooling when available to the perimeter zones. Hot water for space heating is provided by air source heat pumps and chilled water for cooling is generated via air cooled chillers. Multi function heat recovery air source heat pumps are utilised during simultaneous heating and cooling conditions for high efficiency operation.
Sustainability initiatives include LED lighting with occupancy detection and daylight dimming controls, solar thermal hot water heating, air source heat pumps and photovoltaic panels, resulting in an EPC rating of A and a Very Good rating under BREEAM New Construction (Industrial) 2014.
