Controlling outdoor climates is crucial due to climate change. Microclimates affect comfort and energy use in buildings. Warmer summers are making people uncomfortable and increasing energy use in Nordic countries. The layout of tall buildings affects how hot or windy it feels outside and inside. A study in Tallinn, Estonia, found that small changes in building positions can make a big difference in how comfortable it is in summer. This shows that planning tall buildings carefully can make people more comfortable and save energy.
