We now live in the age of the city. More than half of the world’s people live in urban areas, and by 2050 it will be more like 70 percent. At the same time, we are using natural resources 1.5 times faster than the world can replenish itself. With city living set to continue rising, climate change and resource scarcity challenges are only going to increase.
One of the key challenges is to make existing buildings in cities more energy efficient, more water efficient and more renewable, using solutions ranging from the simple – such as insulation – to the more advanced, such as clean energy, building management systems and water recycling measures.
