One of the key purposes of the METC project was to significantly improve TAFE SA's sustainability and energy usage profiles. Through extensive and rigorous consultation, the physical area utilised by the teaching programs was reduced from approximately 38,000m2 to 22,000m2. A saving of around 40% with the associated minimisation of ongoing electrical and HVAC usage. A good example of this was the relocation of approximately 3,000m2 of vehicle storage area to an external secure compound where it had previously been keep within conditioned space.
The project successfully repurposed, reused and adapted some 19,000m2 of existing campus' built environment, which, through clever insertion and careful planning, will allow for another 40 years of use from the campus' infrastructure. It should be acknowledged that the original planning and configuration of the buildings lent themselves to this adaptive reuse, providing good natural daylight penetration, which was further enhanced by opening up workshops and classrooms that had previously been enclosed to both each other and the external environment.
Within the existing buildings, an innovative indirect evaporative air conditioning system provides cooling to workshops and general learning areas, and the new building incorporates excellent cross flow ventilation with high level south lights providing both daylight penetration and motorised warm air relieving louvers linked to the air conditioning system and BMS.
Adaptation of the existing storm water system allowed for the incorporation of a bio-filtration swale system in new car park to treat storm water run-off.
Low VOC materials and finishes have been selected throughout the refurbishment; and the majority of workshop plant and equipment was rationalised and reused across all the programs rather than buying new. Increased amenities for both staff and students to encourage bicycle transport to the site, while car parking numbers were not increased to the site, despite the increase in users.
