A green roof reduces stormwater run-off, provides energy savings through the insulating effect of the growing medium and plants, is unaffected by UV, provides a habitat and food for insects, lizards, plants and birds, moderates the urban heat island effect, and muffles noise within the building. Because of the low rainfall, Christchurch doesn't have as many green roofs or living walls as some other New Zealand cities. But, the display will demonstrate examples that work based on our research into appropriate plants and substrates for the local Christchurch environment.
