What is the primary goal of passive solar design principles?

The primary goal of passive solar design principles is to utilize natural light and heat effectively. This approach aims to maximize the advantages of natural sources of solar energy by strategically designing the building's orientation, windows, and insulation. By doing so, passive solar design minimizes the need for artificial heating and lighting, thereby reducing energy consumption and enhancing occupant comfort.

To achieve this, buildings may incorporate features such as large south-facing windows for sunlight exposure, thermal mass materials that absorb and store heat, and appropriate shading devices to control heat gain in warmer months. This design philosophy focuses on creating a naturally energy-efficient environment, leveraging sunlight throughout the day and varying seasons to maintain an optimal indoor climate.
