A passive solar home works by collecting heat as the sun shines through south-facing windows. Then, energy is retained in materials that store heat, otherwise known as thermal mass. You can benefit from a well-designed passive solar home, as it provides abundant natural light all-year round without the excessive utility bills.
The leading provider of energy-efficient windows in Detroit, Tittle Brothers Construction, discusses the basic elements that make an efficient passive solar home.
Thermal Mass
Thermal mass comes in many forms, including stone, concrete, tile, and brick. They work by absorbing heat from sunlight in the heating season and heat from warm air in the cooling season. Other thermal mass materials such as water and phase change products are more efficient at storing heat than others. If you live in an area with a moderate climate and your home has efficient insulation, the thermal mass present in the furnishings and drywall may suffice.
Distribution Mechanisms
Solar heat doesn’t remain where it is collected. It transfers to different areas of the home through conduction, convection, and radiation. In some homes, small fans and blowers assist the distribution of heat.
Control Strategies
In the summer, roof overhangs can provide shade to vertical south windows, provided they are the right size. An electronic sensing device also makes a good alternative control approach. You can choose from operable vents and dampers, differential thermostat, low-emissivity blinds, and operable insulating shutters, among other devices.
Proper Window Orientation
It is ideal for windows or other devices that collect solar energy to face within 30 degrees of true south. During heating season, from 9 a.m. to 3 p.m., these devices shouldn’t be shaded by buildings or trees. In the spring, fall, and cooling season, on the other hand, the windows should be shaded to avoid overheating.
