Answer:
Passive solar heating system
Step-by-step explanation:
The goal of passive solar heating systems usually refers to the system in which the energy provided by the sun is used for heating and cooling of the living places in a house.
When sunlight falls on the house, the building elements capture the heat energy of the sun and it later releases back this heat when the sun is not there. The main objective of this system is to regulate the room temperature. It is comprised of two main elements, one is the glasses that face towards the south and a thermal mass that is used for heat absorption, storing and distribution of heat.
