The Boronggook Drysdale Library in Australia serves as a model for carbon neutral development. The project features a 544 square meter sloping green roof with over 4,700 native plants, designed to support local biodiversity and manage stormwater.

The geoweb cellular confinement system for those 45 degree slopes is the real technical win here. Most green roofs stay flat because steep slopes are a nightmare for soil migration and maintenance. Curious about the long term cost of that remote irrigation system.
It is a nice project, but I want to see the actual carbon accounting. Calling a building carbon neutral often relies on offsets or specific boundaries. Did they account for the embodied carbon in the concrete and steel used for that circular design?
The 100% renewable energy commitment from the City of Greater Geelong is the most important part. Green roofs are great for heat islands, but the operational carbon depends entirely on the grid mix. I wonder if they have onsite solar or just a PPA.
