Green Leaf was engaged to re-engineer the building services for QCG’s two Brisbane sites. Our role as sustainable designers was to not only to design the services around the base build and fit-out requirements, but with a cost effective sustainable approach.
We worked very closely with the hospital facility maintenance staff to collect data from the BMS and to understand the client’s heating and cooling needs. This data was applied to thermal models to inform our choice of a water cooled A/C system that siphoned ‘free’ cooling capacity provided by the base hospital.
High efficiency lighting was also integrated the design and became integral to lowering the air-conditioning requirements and ultimately reducing capital cost of the HVAC installation. Lighting and A/C controls were also integral to reducing the energy consumption of these two sites with daylight dimming and occupancy sensors.
This installation is the first of its kind in Queensland. In house calculations have revealed the two tenancies will consume 55% less energy than a current best practice medical retail facility. Our hands on, proactive approach to refurbishment work allowed the client to eliminate floor plan air conditioning equipment and install ultra efficient water cooled condensers on the roof, improving net the let-able area, energy efficiency, noise levels and capital costs.
