The building is predominantly mechanically ventilated with supply and extract heat recovery type ventilation equipment in the office areas. The laboratory areas are each provided with variable air volume fume cupboards for extract with supply air provided from a dedicated air handling unit to a positively pressurised lobby and also into the rooms to create negative pressure within the laboratories.
The toilet areas and kitchenette are provided with individual extract ventilation using small extract fans activated by PIR occupancy sensors for energy conservation. The chemical solvent store is provided with permanent high and low level extract ventilation by a ducted ATEX explosion proof extract fan. Efficient VRF (Variable Refrigerant Flow) air source heat recovery systems have been installed to meet the heating and cooling requirements for the laboratories and office areas. The offices are provided with 4 way blow cassette air conditioning units. Ducted type units with supply and return air grilles are located within the laboratory areas. Condensing units are located on the flat roof area over first floor. Water service for toilets, kitchenette and ancillary areas are provided directly from the mains water service.
Although this building is provided with heating, ventilation, comfort cooling, boosted domestic water services and water heating as well as lighting and general power by electric means only it is still fully complies with Part L requirements due to energy saving inverter driven technology, heat recovery ventilation and air conditioning systems, efficient lighting and controls.
