What do green walls do?
When talking about sustainable architecture you listen about green walls and roofs and urban agriculture. It's claimed that plants absorb the CO2 and the pollutants from the atmosphere, wouldn't it be the same for the crops that we will later eat?
Shaun Fitzgerald - I think the topic of green materials for buildings is amazing because one of the challenges that we have in a building is assessing the embodied energy and how much energy or carbon was used to make materials. If you make it out of things like bamboo, it becomes a carbon sequester.
