Derwent Park Developments has achieved a National Australian Built Environment Rating System
(NABERS) 5 Star Whole of Building Rating for its office redevelopment at 169 Main Road Moonah – a
first for Tasmania.

The 5 Star Whole of Building Rating for pre-existing buildings is rare, with the property being one of
a handful of buildings in Australia to achieve this rating and the first of its kind in the State.

Derwent Park Developments Managing Director Troy Harper said construction of the building
concluded in March 2011, with the building being fully refurbished both inside and out.

“In order to achieve this, we took the building back to a concrete shell before commencing
renovations,” Mr Harper said.

“Despite our rugged climate, Tasmania is perfectly capable of producing nationally recognised
energy efficient buildings.

“What makes this achievement even more significant is that the building cost was 50 – 65 per cent
less than the equivalent mainland building.

Tasmanian Executive Director of the Property Council of Australia Mary Massina congratulated
Derwent Park Developments in achieving a Tasmanian first.

“Derwent Park Developments is to be congratulated for this achievement which yet again shows the
private sector in Tasmania is leading the way by taking efficiency and the environment seriously,” Ms
Massina said.

Mr Harper said the success of the redevelopment was not only a testament to the organisation’s
design ingenuity, but also to the energy efficient business practices of Southern Water and
Quarantine Tasmania.

“Both tenants are to be congratulated on their achievements and are now both part of a very select
national group of energy efficient businesses,” Mr Harper said.

Southern Water Chief Executive Officer Mike Paine said a more energy efficient building meant
lower overheads, leading to reduced operating costs.

“Southern Water is committed to being energy efficient and moves such as this ensure that we can
focus on delivering the best possible services to consumers,” Mr Paine said.

NABERS is a performance-based rating system for existing buildings and is based on a building’s
measured operational impacts on the environment, taking into account such factors as energy and
water, waste and indoor environment.
