Mirvac’s workplace at 200 George Street tower provides the company with a “living laboratory” to test out technologies and approaches that improve sustainability. The building has achieved a 6 Star Green Star Office Design v3 rating and a WELL Gold rating, and is targeting a 6 Star Green Star As Built v3, 5 Star NABERS for energy, 4 Star NABERS for Water for the Mirvac fitout. The company has signed a 10 year lease on 6,865 square meters over five floors. The building was developed and built by Mirvac, and the Mirvac Property Trust retains 50 per cent ownership with the balance of ownership belonging to AMP Capital Wholesale Office Fund. The 37-level tower designed by FJMT features a pressurised high performance closed cavity facade with timber blinds within the floor-to-floor integrated glazing units that comprise the building’s skin. The blinds respond to light conditions to reduce glare and thermal loads.
