What makes passive design green?

Passive design is considered green because it maximizes natural resources and minimizes the need for artificial resources, thereby reducing energy consumption and carbon emissions. Passive design uses techniques such as orientation, insulation, ventilation, and shading to optimize natural light, heat, and airflow in a building. By utilizing these techniques, passive design can reduce the need for heating, cooling, and artificial lighting, resulting in lower energy consumption and a smaller carbon footprint. Additionally, passive design can improve indoor air quality and thermal comfort for occupants, making it a sustainable and environmentally friendly approach to building design.
