A bright idea: green power fuels city lights

Sydney's commercial property sector is embracing the concept of energy efficiency, but State Government greenhouse ratings show there is a long way to go.

The Government's latest list of Sydney's greenest office towers shows some building managers are cutting their greenhouse emissions by obtaining their power from renewable energy rather making their buildings more efficient.

In the longer term, that could be an expensive option for building managers unless renewable energy costs fall considerably, according to experts.

More than 27 per cent of the net lettable office building space in the central business district has an accredited Australian Building Greenhouse Rating (ABGR) from the State Government.

Yet greenhouse gas emissions from the commercial building sector are expected to almost double by 2010 from 1990 levels, according to the Australian Greenhouse Office.

Administered nationally by the NSW Sustainable Energy Development Authority, the rating scheme helps building owners and tenants assess their greenhouse performance.

The annual rating - ranging from one star to a top rating of five - depends on how much energy a building uses and how much greenhouse gas emission is attributed to the fuel source.

This year, three of the buildings given a five-star rating scored highly for buying green power but not as strongly in the energy-efficiency stakes.

The use of green power has increased at the top of the list this year because State Government departments must buy 6 per cent of their energy from renewable sources.

By contrast, Central Square in Castlereagh Street was awarded four stars because of the efficiency of its central plant.

"Most of the work we have done has been changes to air-conditioning and lighting to reduce energy consumption," said Jonathan Ryan, director at Henderson & Horning, which manages the building.

"With the right advice it is relatively easy to do."

Building managers are adopting the rating scheme in Sydney partly because the State Government requires all its office premises to be rated, according to Steven Hennessy, director of energy and building services consultancy AHA Management and a rating assessor.

But Mr Hennessy said he had seen a big change in the property industry in recent years. "Building owners are embracing ABGR because tenants want it," he said.

btw GPT's crown was lit up today for the first time in a very long time. Now if only Citi bank would follow suit then the Skyline will once again be completed in lights.
