Dynamic Design Concepts for Hot Climatic Conditions
Published in Neha Gupta, Gopal Nath Tiwari, Photovoltaic Thermal Passive House System, 2022
As discussed in Chapter 6, a Trombe wall is a sun-facing wall popularized in 1964 by French engineer Félix Trombe and architect Jacques Michel. It is regarded as part of the green building envelope (passive concept), which is sustainable for cooling and heating to address the environmental and energy crises throughout the world. A thick thermal mass used as an exterior façade reduces the decrement factor and leads to a time lag. A heavy structure is preferred for thermal cooling as the mass acts as an insulator and a heat storage medium. The unglazed Trombe wall may be constructed with different materials like stone, brick, reinforced cement concrete, mud, etc. For thermal cooling of the building, the exposed solid thick wall should be bare (absorptivity, α ≤ 0.4) and for thermal heating of the building, it should be a blackened surface (absorptivity, α ≥ 0.9)
Energy: Storage

A Trombe wall[11] (after the engineer Felix Trombe who used it extensively) is a form of passive solar energy storage. It is most commonly used in small buildings in combination with other passive energy-saving methods. The wall is a south-facing thick construction of brick or concrete with a layer of glass on the outside and an air space between. The greenhouse effect allows solar radiation to heat the wall but blocks the longer-wavelength, lower-temperature radiation from the wall. The wall stores heat during the day and releases it into the living space at night. Vents with one-way flaps pierce the wall at the top and bottom, whereby cool air from the room enters the air space at the bottom, is heated, rises to the top of the space, and reenters the room through the top vent. The flaps block reverse flow.

Over the course of the heating season, the Trombe wall absorbs enough solar energy to cancel all thermal losses from the building interior through the wall itself and delivers excess heat to the remaining building load. Simulations at Los Alamos Scientific Laboratories support estimates that each square meter of Trombe wall provides 500 to 800 MJ (45 to 70,000 Btu) to the building heating load each season. If the predictable seasonal losses that would have occurred through a conventional wall are taken into account, each square meter of Trombe wall replacing conventional construction will effectively reduce building oil consumption by 36-1 (9.7 gal), or electrical consumption by 19 kWh.

The purpose of utilising Trombe wall is to transfer the stored energy in the Trombe wall to building space for heating or to facilitate air circulation (i.e. setting up convection currents in the room). Results of experimental work carried out by Okonkwo and Akubuo (2007) at Nsukka, Nigeria, showed that brooding temperature range between 28 C and 35C could be maintained in the brooder house under ambient temperature range of 18–37 C while the temperature of the Trombe wall heat storage device ranged between 22 C and 60C. The thermal comfort maintenance cost was drastically reduced with death rate of the chicken dropped to about 3% (about 97%).

Energy is one of the most challenges facing the world today due to the continuous increase in energy consumed and offset by a specific reserve of conventional energy resources(Ahmed 2018). Solar energy is the best renewable energy that can be exploited by humans because it is renewable energy and is not exhaustible and does not result in the use of harmful gases or by-products in comparison to other sources of energy(Ahmed and Hussein 2018)(Khalil Ahmed and Aziz Mohammed 2017). The Trombe wall is one of the passive solar systems that take advantage of the available solar energy in nature and converts it into heat without any electrical or mechanical assistance. A Trombe wall is always located on the southern façade of buildings in the northern hemisphere to increase solar energy throughout the year. The principles of the Trombe wall clarified, as shown in Figure 1.

The thermal energy performance of ventilated Trombe walls is generally related to several weather data (dry-bulb temperature, global horizontal irradiation, wind speed and direction), building design and building envelope performance. The traditional Trombe wall absorbs solar irradiation and transfers heat into the room through conduction and convection. The temperature-controlled ventilated Trombe wall absorbs solar irradiation and transfers heat into the room mainly through convection, thereby enhancing heat exchange between the room and the Trombe wall during the day. The temperature-controlled ventilated Trombe wall can not only solve the problem of overheating during the day and the phenomenon of reverse thermosiphon at night, but also can transfer the heat of the air channel into the room at a fast speed. In this study, due to the room has the low heat storage capacity and poor thermal insulation, the room temperature drops rapidly at night. More efficient ways to use the heat collected from ventilated Trombe wall include improving the building envelope insulation, improving the speed of ventilation and optimizing the location of the air inlets and outlets.
