Electric water heaters from Stiebel Eltron Australia were installed at the new office building located at 1 William Street in Brisbane CBD, contributing to the successful ratings achieved by this project. Designed by Woods Bagot for Cbus Property, the building was constructed by Brookfield Multiplex.

The tallest building on the Brisbane skyline at 259.8 metres, this office building near the Brisbane Parliament House was developed to meet the growing accommodation demands of the Queensland Government.

Designed with the environment in mind, the building has not only achieved a 5-star accredited NABERS energy rating but also a 5-star Green Star rating. Stiebel Eltron supplied 140 electric instantaneous hot water units to the development, contributing to the energy and green ratings achieved by the building.
