Green roof

The phrase green roof is slightly misleading when applied to the nearly 3000 plants on top of the University’s William James Psychology Building. In fact, it is a multicoloured mosaic – containing a range of drought resistant Otago natives of orange, gold and red as well as green.

The plants include Coprosma, the native Iris Libertia and native daphne Pimelea.

They are planted in a low fertility, pumice-based substrate between 10cm to 15cm deep and filter rain water for use in the building’s toilets, saving around 350,000L of drinkable city water each year.

Dr Janice Lord of Botany (pictured above with Property Services Energy Consultant Mark Mason) selected, planted and maintains the plants. Botany also uses it as a research and teaching tool for postgraduate and senior students.

The roof is believed to be first of its scale in the South Island and the first on an educational building.
