Passive solar heating systems capture sunlight and release it when the sun is not present. They use materials to absorb heat during the day and release it at night. Passive solar cooling systems reduce heat gain during the day and use exterior conditions as a heat sink.
Passive solar heating and cooling systems can reduce energy usage by 80%. This can lead to lower energy bills, reduced carbon emissions, and less environmental impact. Passive solar heating is most effective in climates that are not too hot or cold. It works best in smaller buildings with good exposure to the sun.
