Green roofs a smart choice in South-East Australia

10 August 2018

Congratulations to Andrea (Andrew) Pianella on recently completing his PhD on the thermal behaviour of green roofs in South-East Australia.

Andrew quantified the effects of substrate, soil moisture and vegetation cover on green roof temperatures and heat flux.

His research reveals that a 150mm deep green roof on a single-storey brick office with a concrete roof can potentially save up to 65 per cent in heating and up to 35 per cent in cooling loads, and will make it easier to select substrates and plant species to deliver the best thermal performance.

It also brings new precision to calculating the energy benefits of green roofs, facilitating their inclusion in sustainable building rating schemes such as Green Star.

The GIRG team were excited to celebrate Andrew’s graduation with him on Friday 27 July at the Royal Exhibition Building and congratulate him on his contribution to green roof knowledge and practice.
