City shadows reveal its energy flow

By calculating the amount of solar radiation reaching streets and buildings, researchers could help optimise the way energy is used in our cities.

The research team developed “shadow models” and a new type of software to determine what happens to sunlight once it enters our cities.

Results from the study can be used to search for greater harmony between human and natural energy consumption. For example, a building that is heated at night might have enough solar radiation falling on it during on the day to retain the heat created at night.
