What Is A Trombe Wall And How It Plays Role In Passive Solar Architecture Design?
A Trombe wall is a type of passive solar architecture design which functions as an insulating buffer between the exterior environment and the interior of a building.
The wall consists of an outer brick, concrete or masonry surface with one or more layers of glazing on the outside and an air space between them.
This air space allows for thermal insulation, creating an air gap that helps reduce heat flow from inside to outside.
Heat from sunlight is absorbed by the dark-colored material on the outside, while cooler air is maintained on the inside.
The absorbed heat is then released gradually into the living areas during colder ambient temperatures to warm up interiors naturally.
Having a Trombe wall installed can significantly reduce energy consumption in buildings, resulting in lower bills and increased savings over time.
Who Invented Trombe Wall?
The Trombe wall was invented by French engineer Felix Trombe in the 1970s. It is an energy-efficient passive solar heating and cooling system that uses a dark wall connected to a glazed opening on the south side of a building, designed to absorb the sun’s heat.
The air between the wall and window forms a cavity which acts as a thermal battery; when opened, it picks up heat from the sun during the day which are released into the house at night.
This helps to reduce energy consumption and lower heating bills without any additional mechanical equipment or maintenance costs.
Where Are Trombe Walls Used?
Trombe walls are an innovative passive solar technology developed in the 1970s. They are a type of double-wall construction consisting of an outer wall of solid masonry or concrete materials, coupled with a large south-facing glass panel and an inner wall made of masonry or different types of insulating materials.
The air between the two walls is heated by absorption through the glass, then drawn into living spaces via vents.
Trombe walls can be used as both interior and exterior walls to capture heat from direct sunlight, store it during the day and slowly release it at night to maintain comfortable temperatures without any additional energy source.
In addition to providing winter heating, they also provide cooling in summer by allowing for naturally ventilated airflow.
Trombe walls can be found in many climates around the world, including temperate areas such as Canada and northern states in the U.S., as well as tropical regions like South Africa, India and Brazil.
How Does A Trombe Wall Aid In Energy Conservation?
A Trombe wall is an energy-conservation strategy that uses the thermal properties of materials such as concrete, brick and stone to absorb and store the sun’s energy during the day and then release it again in the evening.
A Trombe wall utilizes a dark absorber plate that heats up when exposed to sunlight. The air between this plate and an outer glazing is heated by conduction, convection or radiation and stored in a thick masonry wall behind the glazing.
This heat is then released gradually at night to maintain warmth inside the building, allowing for significant savings in heating costs.
Additionally, air behind the absorber warms up during summer days, resulting in natural ventilation that replaces or reduces mechanical cooling systems.
Are Trombe Walls Still Used?
Trombe walls, named after French engineer Felix Trombe, are passive solar thermal energy collectors that use the sun’s radiation to heat up a wall of masonry.
Due to their effective design, they have been used since the 1970s to help people reduce their heating and cooling expenses while still providing moderate temperatures inside buildings.
Despite their long history, however, their usage has decreased significantly in recent years due to advances in air conditioning technology and the rise of photovoltaic cells.
Although Trombe walls are no longer widely used as a means of providing home heating or cooling, some installations are still seen in certain regions with high levels of solar radiation and inadequate access to conventional energy sources.
What Are The Advantages Of Trombe Wall?
Trombe walls are an efficient and cost-effective way to provide passive heating and cooling for buildings.
They offer many advantages including lower energy costs, passive solar gain, improved air quality, reduced maintenance, and increased interior comfort.
Trombe walls also help reduce the amount of energy used to heat or cool a building as they act as thermal mass that can store and release heat.
This helps keep the temperature more even throughout a day by reducing the daily cycle of heating and cooling needed.
Additionally, Trombe walls require very little in terms of upkeep meaning less maintenance compared to other forms of climate control such as electric space heaters or air conditioning systems.
Furthermore, due to their thermal mass properties they can act as a buffer against outside temperature extremes which increases interior comfort levels.
What Are The Disadvantages Of Trombe Wall?
Trombe walls can have some serious drawbacks.
- Firstly, they require the installation of very thick and expensive walls that may not fit into the existing design of a building.
- This is especially true if you are trying to make an existing structure green using a trombe wall.
- Additionally, these walls must be constantly monitored and maintained in order to ensure maximum efficiency from them.
- Poorly designed or maintained trombe walls could also lead to overheating since inadequate ventilation around the wall can cause it to absorb too much heat from the sun.
- In addition, the Trombe wall requires a lot of energy for construction and its materials aren’t always available or easy to source.
All these factors may make installing a Trombe wall cost prohibitive for many people.
