How thick should a Trombe wall be?
8- to 16-inch thick
Trombe Wall Construction
A typical Trombe wall consists of an 8- to 16-inch thick masonry wall coated with a dark, heat-absorb- ing material and faced with a single or double layer of glass. The glass is placed from about 3/4″ to 6″ away from the masonry wall to create a small air- space.
How effective is a Trombe wall?
While passive solar techniques can reduce annual heating demand up to 25%, specifically using a Trombe wall in building can reduce a building’s energy consumption up to 30% in addition to being environmentally friendly.
Can a Trombe wall have windows?
Architects can use Trombe walls in conjunction with windows, eaves, and other building design elements to balance solar heat delivery. Strategically placed windows allow the sun’s heat and light to enter a building during the day to help heat the building with direct solar gains.
Is a Trombe wall direct gain?
A Trombe wall is a system for indirect solar heat gain and, although not extremely common, is a good example of thermal mass, solar gain, and glazing properties used together to achieve human comfort goals passively.
How does a Trombe wall work in winter?
At night, a Trombe wall functions differently. The vents at the top and bottom of the wall are closed to ensure that the now cool air in the channel between the glazing and the wall doesn’t re-enter the home. Heat absorbed by the concrete wall is still able to maintain a comfortably warm internal space overnight.
What is the best thickness of the Trombe wall with vent and without?
It was recommended to use a fan for vented type trombe wall and a suitable insulation, which improves the efficiency by 8% and 56%. Optimal size and thickness of the wall of trombe wall was found to be 37% and 30–40 cm for its optimal performance.
How does Trombe wall work in winter?
b) Trombe walls in the winter: In the winter, when the sunlight hits the wall, the wall gets „charged‟ up to warm the house by transferring the sun‟s heat inside. The thermal mass in the trombe wall will gradually boost as it absorbs heat energy, and then will gently release it.
What is the best thickness of the Trombe wall with vent?
Optimal size and thickness of the wall of trombe wall was found to be 37% and 30–40 cm for its optimal performance.
How does Trombe wall work in summer?
In the daytime, Trombe walls facing the Sun have sunlight incident upon them. The wall absorbs and stores the heat coming from the direct solar radiation. Cool air from the building enters the air channel between the wall and the glazing through a vent that is present at the bottom of the wall.

Is Trombe wall sustainable?
Trombe walls are regarded as a sustainable architectural technology for heating and ventilation.
Who invented Trombe wall?
A Trombe wall is a wall with high thermal mass used to store solar energy passively in a solar home. It is named after the French inventor, Felix Trombe, who popularized the design in 1964 although Edward Morse had patented it back in 1881.
