“…The dimensions of the inlet and outlet openings are increased by changing the width of the channel, while increasing the distance between the wall and the glazing also increases the ventilation rate [22]. Liu and others [29] have experimentally and numerically determined that the optimum time to open the ventilation ducts on the Trombe wall is 2-3 hours after sunrise, while the optimal closing time is 1h before sunset. Trombe wall reaches the maximum value of the capacity of the heat accumulation at 16h, while the minimum value is recorded at about 7-8 o'clock in the morning.…”

Energy consumption has reached its highest level globally. Buildings have the largest share in total energy consumption, so designers must take into account their functioning and the consequences that can arise. Passive solar design is an imperative in modern architecture, and Trombe wall, as one of the principles of this design, is certainly distinguished. The paper presents an overview of the characteristics of the construction of the Trombe Wall in order to improve thermal stability and reduce energy consumption in buildings. Starting from the consideration of climatic influencing factors, through the heat capacity of the materials applied and their thickness and color of the thermal mass, it is very important to know in detail all the factors that can lead to the improvement of the efficiency of this system. The specific heat of the walls in the building, the time delay, the decrement factor and the influence and position of the thermal insulation were also taken into account. The effect of glazing as well as the influence of the ventilation openings were highlighted as significant elements. On the basis of the analysis of the above components, the conclusions and guidelines for designing this type of constructions were made in order to improve the efficiency and reduced energy consumption while providing adequate comfort in the facility.

“…Studies conducted on this area are essentially about Trombe walls with ventilation openings in the massive wall. As an example of the studies already developed addressing this issue, an optimization research on the opening and closing model of the Trombe wall was conducted using experimental research and numerical calculation [30]. The optimum time to open and close the air vents was analysed.…”

a b s t r a c tDespite the studies already developed about Trombe walls, more research work is needed to contribute to the knowledge about their behaviour and optimize it according to the specific characteristics of each climatic region. The ventilation openings and the shading device operation decisively influence the temperatures fluctuation along the system and that impact should be discussed.In this context, a test cell with a classical Trombe wall was submitted to real climatic conditions in a Portuguese city. The effect of ventilation openings and shading devices in the temperatures fluctuation was analysed.The temperatures in the air layer and along the massive wall presented a similar oscillation pattern and exceeded 60 • C without ventilation and shading devices. For this configuration, temperature values at the top of the air layer were always higher than those obtained at the base and a differential of 19 • C was achieved.The temperature fluctuation across the massive wall was not proportional to its thickness due to its heat storage capacity. When the ventilation system was closed and the shading device was not activated, the temperature inside the test cell exceeded the outside temperature value in 9 • C, showing the system ability to store and release heat.
