Abstrakt: The objective of this research is twofold. First, it aims to evaluate the impact of an urban park on the thermal behavior of residential buildings. Second, it focuses on developing and validating metamodels for predicting the cooling needs and summer thermal comfort of three types of residential buildings: single-family houses (Low-rise), small collective housing (Mid-rise), and large collective housing (High-rise). The metamodels are created through regression analysis, using a set of dynamic thermal simulations conducted with TRNSYS software. The number of dynamic simulations is efficiently reduced using the design of experiments method, and the accuracy of the metamodels is further validated through additional simulations. This study was conducted considering the climate weather conditions of the city of Nantes, France. The results demonstrate that an urban park can achieve a maximum reduction of 12.53 % in cooling needs and a 12.50 % maximum reduction in degree hours of discomfort, particularly when the building is protected from solar radiation. Furthermore, developed metamodels show high accuracy with regression coefficients over 0.96. This study aimed to create a decision support tool for local government departments to optimize urban cooling, improve thermal comfort, and reduce cooling loads in buildings by guiding the design of parks and their surrounding built environment. [Display omitted] • Impact of urban planning, building typology and building envelope on the cooling effect of parks. • Developed metamodels to predict the impact of urban parks on cooling needs and thermal comfort in building. • Metamodels serve as decision-support tools for effective urban planning. • Urban parks can reduce cooling needs by up to 12.53 % and discomfort by 12.50 %.
