The new 1,000m2 office building in Brisbane’s Fortitude Valley quietly beat the field to receive the first Green Star Design and As Built v1.1 certified rating in Australia. Remarkably 69 Robertson Street’s project team did this by achieving the highest possible rating of 6 stars, with an impressive score of 83.3 points awarded in just one round of the assessment process.

Floth Sustainable Building Consultants, an independent Australian specialist engineering firm, developed and occupy the three level office building. They undertook the building services engineering and Environmentally Sustainable Design (ESD) and moved into the upper two levels in August 2015. The constrained zero lot line building designed by Mondo Architects includes green trellis walls with drought tolerant climbing vines growing up the external faces of the central light well and rear decks. While the planting has been carefully selected to thrive without additional irrigation, roof rainwater is still being collected for green wall establishment and for toilet and urinal flushing.

The new office building is fitted with the latest occupancy- and daylight- controlled direct- indirect LED lighting systems. Heat recovery variable refrigerant flow air conditioning systems are literally able to move heating or cooling from one part of the building to another as required. High indoor air quality is assured with a 50 percent increase in outside air being delivered to occupants via variable air volume systems that are demand controlled in response to zoned carbon dioxide sensors. Many other features and a host of GBCA-recognised innovations were elegantly integrated in the otherwise conventional building without significant additional cost.

Floth shares a distinguished history with the site, which was bought back in 2000 when it was occupied by a venerable Queenslander that was actually built by the Robertson family (after which the street is named). The converted Queenslander served as the Floth state offices until 2003. The Queenslander was eventually removed from the site and preserved for future generations by being transported to Esk to become the new home of a family who lost their house to fire.

Beyond Green star, this is the first building that has formally and publicly adopted the Australian Sustainable Built Environment Council’s (ASBEC) standard definition of a zero carbon building. A 53 percent reduction in operational carbon emissions is predicted from facade and integral building services improvements (compared to an equivalent Building Code compliant energy model). A roof-mounted solar photovoltaic system achieves a further 13 percent reduction, also equivalent to offsetting 28 percent of the building’s final operational energy. 100 percent accredited GreenPower purchased from Origin is the final piece of the zero carbon puzzle. Over the base building, both Floth’s and the eventual Level 1 tenant’s fitouts will effectively be zero carbon in operation by virtue of the 100 percent GreenPower supply. Notably the free electricity generated by the solar photovoltaic system will more than offset the additional operational cost of the GreenPower. Given the cost effectiveness of the building, it would be difficult to come up with a better solution.

Floth have recently achieved the first 6 star NABERS Indoor Environment rating in Australia for the Floth tenancy at Level 2 & 3, 69 Robertson Street, Fortitude Valley.

A number of other sustainability certifications are currently being targeted, including the National Australian Built Environment Rating System (NABERS) Energy and Water and the US Green Building Council’s LEED (Leadership in Energy and Environmental Design) New Design and Construction rating system.
