The number of buildings in Sydney and Melbourne that are covered with vegetation pales in comparison to London, Rotterdam, Singapore and Toronto, according to an analysis.
Otherwise called green buildings, there are 123 green roof and wall projects in Sydney since 2016. Melbourne had a significantly lower number with just 28 similar projects in the last two years.
Singapore currently leads in terms of having green roofs and walls in its buildings. The analysis showed that if Sydney adopts the city-state’s system over a long-term period, it would have more than 3,245 green buildings by 2032. A short- and mid-term implementation of the same system would increase the city’s green buildings to 453 and 1,668 properties, respectively.
In Melbourne, choosing to add more green buildings in the next five years would increase the city’s portfolio to 103 properties. The mid- and long-term adoption of Singapore’s building standard could result in more than 570 green buildings by 2032. The benefits of including vegetation in building designs involve more than just energy-efficiency, but also cost-savings for household electricity bills.
A report showed that enforcing stricter energy-efficiency standards would provide homeowners with $18.9 billion of electricity savings from now up to 2050. Multifamily buildings would particularly benefit from improved standards.
While more greenery seems a good option, property owners and managers should consider other simple ways to monitor building performance. Some cases simply require you to check if there is a need to replace the building’s centrifugal pump or other parts of its heating, ventilation, and air-conditioning system.
An expansion of buildings with green roofs and walls in Australia would require better regulations, more public and private investments. Properly insulated buildings can significantly reduce energy consumption, while helping HVAC systems perform better at the same time. How do you keep up with sustainable building trends?
