Quick Summary

Passive solar energy utilizes architectural design to heat buildings using sunlight. This approach involves strategically positioning the building, designing its structure, and selecting materials to maximize solar heat gain and natural lighting. For example, a well-insulated building with large south-facing windows can trap heat on sunny days, reducing the need for conventional heating fuels. Interior elements like brick or tile can absorb solar heat and radiate it back into the building later. This method aims to lower or eliminate a building's fuel requirements by harnessing the sun's energy through thoughtful design.1

…use in residential buildings is passive solar radiation. On sunny winter days, south-facing windows let in substantial amounts of energy, often enough to heat the entire building. Wood-burning fireplaces with chimneys are still widely provided in residential buildings, but their use is mostly for aesthetic effect.
