Microclimate simulations are in high demand to assess the thermal impacts of urban design and vegetation changes. Modeling accurate microclimate dynamics complex settings requires extensive computing power. A hybrid Python approach is introduced simulate human exposure (mean radiant temperature, MRT) comfort (Universal Thermal Climate Index, UTCI) cities. The proposed model combines various engines Rhinoceros account for interactions between surfaces, tree canopies, atmosphere. was validated hot, dry Tempe, USA, using in-situ human-biometeorological observations then applied archetypes Bologna Imola, Italy. MRT UTCI were simulated at five sites Bologna, four with varying building heights canopy cover climatologically hottest week year (August 3–9). performed well an RMSE 5.4 °C, index agreement 0.96, outperformed existing models tree-shaded sites. driven mainly by shade from dense forms trees. Highrise, medium-to-high coolest concerning comfort. Sites Tempe exceeded categories Very Strong or Extreme Heat Stress independent archetype. enables fast assessment planting strategies.

Heat exposure for urban populations has become more prevalent as the temperature and duration of heat waves in cities increase. Occupational to is a major concern personal health, excessive can cause devastating outcomes. While occupational studies have traditionally focused on environmental temperature, work intensity, clothing, little known about daily profile workers, including their travel working patterns. This study developed novel measure reprieve dynamics, moving average hourly (MAHE) balance short-duration but high-exposure events capture inability from events. MAHE was assessed by combining an activity-based model (ABM) Requirement Survey simulate workers' total exposure. The simulation considers travel, schedules, outdoor frequency. conducted 1 million workers Phoenix, Arizona, using Mean Radiant Temperature (MRT). results show that 53–89% Phoenix's construction, agriculture, transportation, raw material extraction, entertainment industries will likely experience over 38°C at least hour. These also up 34% laborers exposed 7 hours continuous above location most intense identified near downtown central business districts, significantly different home locations suburban rural areas. Formulating balances risk with cooling benefits aids identifying individuals prolonged high
