Passive solar heating uses energy efficient home design for solar heating.

using a material to collect and store thermal energy from the sun.

A system that uses certain building materials (such as masonry) to collect and release energy from solar radiation.

A system that captures sunlight directly within a structure and without the use of mechanical devices, and converts it into low-temperature heat for space heating or for heating water for domestic use.

The maximization of the sun's heating abilities through careful design of a building.

A solar heating system using a simple solar collector, building materials, or an architectural design to capture and store the sun's heat. Very simple examples include a garden greenhouse, or a south-facing window in a dwelling.

A solar heating system that uses a simple solar collector, building materials, or an architectural design to capture and store the sun's heat, but that does not include any mechanical system to transfer the heat to various parts of a home or building.

A system of features incorporated into a building's design to use and maximize the effects of the sun's natural heating capability.
