District cooling A solution against concentration of heat in cities (Source: Climespace) Heat island effect: Increasing temperatures in the cities center due to: Heat dissipation from human

cooling demand Case study of Paris The installation of conventional dry air conditioning system significantly increases the heat island during the summer period 1.

10 District cooling A solution against concentration of heat in cities (Source: Climespace) Heat island effect: Increasing temperatures in the cities center due to: Heat dissipation from human activities Urbanization: higher heat absorption from solar radiation Strategic importance of choosing the type of cooling technology by: Controlling the projected energetic solution Meeting the cooling demand Case study of Paris The installation of conventional dry air conditioning system significantly increases the heat island during the summer period 1. They contribute to an increase at night time of 0.5 C in city center areas If all the cooling demand is satisfied by conventional units, and not from DSC, the impact will be in the order of 1 C to 2 C If by 2030 the cooling demand is met only by conventional air conditioning systems the impact will be in the order of 2 C day time city centre, 2.5 C night time and 0.5 C on the outskirt of Paris 1.
