A mixed mode ventilation strategy will be adopted for the whole building. This includes mechanical ventilation with heat recovery in winter, natural ventilation assisted by earth ducts for passive cooling in the summer.
The mechanical ventilation strategy allows the thermal energy extracted from the exhaust air to be used to heat the supply air, thus dramatically minimising the need for additional heating in winter.
The earth ducts will supply naturally cooled fresh air to the AHUs. The exhaust air extracted at high level through wind cowls located above the roof. A displacement ventilation system will supply low velocity fresh air from low level and extract exhaust from high level within the building.
To further minimise energy consumption, energy efficient lighting, i.e. fluorescent and LED lamps will be installed inside and outside the building. Daylight dimming sensor will be provided around the perimeter areas and occupanct sensors will be installed in storage, toilets and changing facilities. PVs will be incorporated into the scheme to offset approximately 46% CO2 emissions arising from fans, Pumps & lighting. The estimated peak output is around 55kW. The project aspires to achieve BREEAM Outstanding.
