Passive system design principles focus on maximizing the use of natural resources for heating, cooling, and lighting a building without relying on mechanical systems. The essence of passive design is to create comfortable indoor environments by harnessing elements such as sunlight, wind, and thermal mass, rather than using energy-consuming mechanical systems.

The usage of mechanical heating and cooling systems directly contradicts the fundamental concept of passive design, which seeks to reduce or eliminate the need for such systems. Instead, passive design prioritizes strategies like optimizing building orientation to maximize solar gain and configuring spaces to encourage natural ventilation.

Choosing options related to natural airflow and daylight, building orientation optimization, and thermal mass application all align with the goals of passive design, highlighting the effectiveness of these strategies in enhancing energy efficiency and comfort within a structure.
