The potential radiation temperature is determined by the radiation that reaches a human body in the city. This radiation is a combination of shortwave radiation (light) and longwave radiation (infrared) that appears directly on the body or is projected indirectly via reflection on buildings and the ground on the body. The sky view factor is an important parameter in calculating direct and indirect radiation. The urban heat island effect (SHE) occurs when there is a temperature difference between city and surrounding countryside and is mainly the result of the built-up and paved environment. The SHE is the largest at night and is particularly noticeable during the summer months. The most well-known consequence of this effect is the ‘heat stress’ or the ‘feeling of unease’ in hot temperatures. During heat waves and especially at night, heat stress can lead to health problems and even mortality, especially among sick, young (-4y) and older (+65y) populations. Other consequences of the SHE are the failure of infrastructure, machinery, reduction of labour productivity, reduced lifespan of materials... The city of Antwerp mapped out the SHE in the first instance to develop a prevention and communication policy for its residents, companies and visitors and to take policy measures to increase the quality of life in the city. In the second instance, this research is part of the preparation of the Antwerp Adaptation Strategy, which systematically maps out the city's challenges with regard to climate change. The same study found that the SHE will increase as a result of global warming.
