Abstract

This study presents a comprehensive framework for assessing indoor environmental quality by integrating coupled mass and heat transfer mechanisms within building envelope models. Recognizing that indoor air quality, thermal comfort, and energy efficiency are interdependent, the research aims to holistically evaluate how building materials, ventilation strategies, and occupant behavior influence human exposure to pollutants and overall energy performance. The model simulates simultaneous heat and moisture transfer through walls, windows, and ventilation systems to capture dynamic indoor conditions. Human exposure metrics are incorporated to assess occupant health risks, while energy modeling evaluates system efficiency under varying environmental conditions. The findings emphasize the importance of an integrated approach in building design, providing valuable insights for architects, engineers, and policymakers focused on creating healthier and more energy-efficient indoor environments.
