Building science primarily focuses on the interactions of heat, air, and moisture within buildings and their environments. This field seeks to understand how these elements affect the performance, durability, and energy efficiency of buildings.

Heat flow involves understanding thermal dynamics, such as insulation, heat transfer, and temperature regulation within the building envelope. Air flow considers how ventilation, air leakage, and pressure differences influence indoor air quality and climate control. Moisture flow is critical to prevent condensation, mold growth, and degradation of building materials, affecting both comfort and structural integrity.

Together, these three flows create the conditions for how a building performs over time, influencing energy consumption, occupant comfort, and overall sustainability. Other options do not encompass the core tenets of building science, as they focus on elements that are either not as directly relevant to indoor environmental quality or do not pertain to the fundamental principles that affect building performance.
