North America Modeling Students Elementary (K-5) Middle/Jr High (6-8) High School (9-12) Ventilation rates Carbon Dioxide (CO2) Odor Absenteeism Cognative function Natural ventilation Indoor air quality Human bioeffluents Human body odor Education buildings Multi-objective genetic algorithm A multi-objective optimization model simulates natural ventilation and cost in classrooms to control body odor from human bioeffluents. Results support ventilation-based design decisions to improve occupant satisfaction and reduce energy use in schools.
