The City of Sydney plans to make the sustainability credentials of apartments more transparent to residents.
The City reported strong community support for the residential apartments sustainability plan, which has suggested the introduction of higher energy efficiency targets and better compliance for the existing Building Sustainability Index, known as BASIX.
Lord Mayor Clover Moore said it was important to ensure residential buildings are designed to lower greenhouse gas emissions, reduce waste and water use, and that owners are aware of their apartment’s green credentials.
“Over 70 per cent of the City’s residents live in apartments and this is estimated to increase to 80 percent by 2030. That’s 270,000 people living in apartments in the inner Sydney area,” the Lord Mayor said.
“The number of apartments is increasing, but the minimum sustainability targets for new apartment buildings, are much lower than for new houses.
“Retrofitting buildings can be costly, so it’s better to include higher sustainability standards at the design stage.”
The Lord Mayor suggested that prospective buyers of new apartments could be shown a BASIX ratings certificate, so they can be aware of how well the building performs environmentally.
“We’ve already seen how buildings with better sustainability standards can reduce bills for owners and tenants in the long run, and this is a major selling point for new apartments.”
The residential apartments sustainability plan used data from the City’s Smart Green Apartments program – a three-year sustainability trial that took place in 30 buildings across the city from 2011–13.
An independent evaluation of 21 of those buildings last year found environmental retrofit projects helped result in an annual reduction of more than 3000 tonnes of carbon emissions per building, with savings of up to $90,000 per building each year.
The City has allocated $400,000 to develop a High Rise Leaders Retrofit Program to make existing apartment buildings more sustainable.
The United States-based Carbon Neutral Cities Alliance has also given the City a $60,000 grant to help increase the number of high-rise residential buildings that create their own energy from solar and other sustainable sources.
The City will advocate for residential apartment buildings to be included in State and Federal government subsidy schemes.
“The community wants higher environmental standards in new apartment buildings and has asked us to encourage developers to increase their sustainability goals by offering incentives for water-saving devices, solar photovoltaic panels and bicycle parking in new buildings,” the Lord Mayor said.
“As we’ve seen in the commercial property sector, buildings with improved green standards are more attractive to new owners and residents who demand reduced operating costs and better environmental performance.”
