“…Florides and associates [17] conducted the analysis which have shown that, in relation to the thermal mass, the increase in the wall and the roof thickness and the use of night ventilation is not enough to reduce interior temperature to acceptable limits during summer. In cases where space heating is intensified during the day, it is necessary to try to use walls with a lower thickness of thermal mass [8].…”

“…It is also preferable to apply a combination of 20 cm thick thermal mass and a single glazing compared to a 10 cm thick wall with a triple glazing. The thermal mass made of 45 cm thick wall in combination with single glazing is also a better option compared to a 20 cm thick thermal mass combined with a triple glazing [8].…”

“…It is extremely important to take into account the economic aspect and the cost of construction as well as the savings during the lifetime of the facility (Life cycle costing -LCC) [7]. It is recommended to use passive solar systems regardless of their price, as this reduces energy consumption, preserves the natural environment and reduces the emissions of gases which contribute to the greenhouse effect [8]. Many studies have shown that the combination of multiple strategies is generally more effective than applying one strategy.…”

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.

“…Cold air passes from the lower opening of the wall, then the air is heated through the channel and moves into the room through the upper aperture. Meanwhile, heat transfer through the thermal wall needs more time to move to the room . The Trombe wall is covered in the summer to prevent excessive warming in hot weather .…”

Global energy demand for the future can be met using renewable energy resources, and one of its harvesting tools is the photovoltaic (PV) technology. The combination of solar cell technology and Trombe wall is one of the most important research topics at present. PV-Trombe walls are receiving great attention because of their applications for simultaneous electricity generation and heating. In this article, a review of available literature covers different designs of a PV-Trombe wall system besides its thermal and electrical applications. The review covers in detail the influence of design and operational parameters including the glass cover, use of direct current fan, facade width, air vent, air gap thickness, thermal insulation, packing factor, coverage, heat storage, air mass flow rate, PV cell cooling, southern windows, and tilt angle of solar cell on the performance of PV-Trombe walls. Furthermore, comparison between the PV-Trombe wall system and classical Trombe wall as well as the applicability of this novel system are revealed. This review article is beneficial to engineers and researchers and can provide information for future studies.

“…where S is the net solar intensity which the Trombe wall absorbs, N is number of days in winter and A r is the Trombe wall receiving surface area in m 2 , L TW is the monthly thermal load of the Trombe wall system measured in GJ (Fares, 2012). During day, heat is transmitted by convection through the air vents.…”

AbstractIn the coming years, it is anticipated that if we continue with the same pace of energy consumption, communities will continue to face three major challenges; a mounting increase in energy demands, pollution, and global warming. On a local scale, Egypt is experiencing one of its most serious energy crises in decades. The energy consumed in indoor cooling and heating is the biggest portion of total energy consumption in residential buildings. This paper is an experimental simulation study for building retrofitting in off-grid settlements in semi-arid climates, using Trombe wall as a low-tech passive heating and cooling solution. In this study, we made developments to the conventional classic Trombe wall using occupant-centered design and living lab experimental methods. The thermal efficiency of the proposed Trombe wall design is simulated during winter and summer peaks. In the proposed design we used gray paint instead of typical black paint in addition to 15 cm reversible natural wool insulation and two 3 mm thick roll-up wool curtains. The new design reduced the heating load by 94% and reduced the cooling load by 73% compared to the base case with an annual energy savings of 53,631 kW h and a reduction in CO 2 emissions of 144,267 kg of CO 2 . The living lab test proved that the proposed design of the Trombe wall is economically viable and the payback time is 7 months. It is recommended that the proposed design be monitored for a whole year to have an accurate assessment of its efficiency. A post occupancy evaluation is also needed to measure local residents' acceptance and perceived comfort after retrofitting.
