Mosaic is a mixed-used residential tower, located in the heart of Fortitude Valley. The landmark development is the first residential tower within the cultural hub of the Valley locale and consist of 18 storeys with 3,000m2 of retail space. Featuring 212 apartments and incorporating an additional 40-room boutique hotel, Mosaic provides a functional link between popular neighbouring entertainment precincts, James Street and Emporium.

Floth Sustainable Building Consultants was appointed to undertake the mechanical, electrical, fire & hydraulic specifications of the building as well as ensuring the integration of Green Building Council of Australia’s Green Star initiatives.

As part of Floth’s ecologically sustainable design (ESD) plan for the building, Mosaic’s construction encompasses several innovative ‘green’ measures which will reduce overall energy consumption and cost whilst also minimising the impact of the building on the surrounding environment. The air-cooled system also eliminates the need for cooling towers thus contributing to Mosaic’s visual amenity.

The engineering of naturally ventilated corridors as part of the ESD plan helps to reduce Mosaic’s energy consumption by approximately 25,000kWh per annum and improves the building’s carbon footprint by 25 tonnes per annum.

As part of Floth’s electrical undertaking of the project, photovoltaic solar panels were installed that will offset the landscape and common area lighting energy consumption. In addition the landscaped and common areas are equipped with time and motion switched energy efficient lighting to minimise the energy consumption.

In order to ensure water efficiency, Floth designed water-saving fittings in each apartment which is projected to reduce the predicted water consumption by up to 33 litres per person per day.

Additionally, water meters were installed in each apartment which will ensure residents pay only for their individual usage, whilst also allowing Mosaic management to monitor the ongoing costs of the building.

Floth developed a recycled irrigation system for the picturesque Mosaic rooftop and pocket gardens, encouraging a self-sufficient, environmentally sound, and blooming Mosaic landscape.

The intelligent architectural design of the structure, in conjunction with the natural ventilation, and the energy efficient equipment distributed throughout the development, will reduce Mosaic’s potential greenhouse gas emissions by up to 15 per cent.
