Solar chimneys as cost-effective renewable energy systems offer significant energy saving in buildings through the enhanced natural ventilation. Previous studies have focused on the fluid dynamics of the solar chimney itself. Still, few studies were found in the literature on its assessment on the energy performance in buildings, such as addressing how many percentages of energy can be saved based on it in buildings. This is mainly due to the relevant challenges of the assessment methods, such as absent functions, modeling accuracy, experimental validation, and the capability of addressing many influencing factors. To overcome the constraints, five typical energy assessment methods were critically reviewed through this review, including hydrostatic pressure, thermal network, zonal model, theoretical/empirical models, and computational fluid dynamics (CFD) modeling. This is the first review paper specified for the energy assessment methods of solar chimneys. The major influencing factors of solar chimney include configuration, installation conditions, material usage, and environment. The current energy assessments for solar chimneys are primarily based on the thermal network and zonal model (or the combination) but not CFD modeling. The current challenge for hydrostatic pressure analysis is its applications in multiple chambers, especially with those large openings (e.g., doors and windows). The thermal network could overcome this challenge, but its modeling accuracy and generality still require effort. Due to many influencing factors, a single assessment method may not be viable for practical implementation. Future research on energy assessment could be in several directions, such as a combined zonal and CFD modeling, the validity and uncertainty of those energy assessments in practical building applications, and detailed and comprehensive experimental tests for the validation.

The present study aimed to develop a computational model to understand the effect of air gap depth on the Trombe wall system. The simulation was performed for midday of January 17, 2017, at a Kirkuk city/Iraq; at this time, the solar intensity was at a maximum value equal to 487.1 W/m2, ambient temperature 10.1°C, and wind speed 0.7 km/h. The result of the simulations is investigated with the experimental work in the literature. The various parameters such as thermal efficiency, inlet and outlet temperatures from air gap, room temperature, and air mass flow rate in the air gap channel have been considered in simulation. The comparison result showed a good agreement between the predicted results and experimental work. This research work will be useful for the research community to understand the effect of air gap depth in Trombe wall system.
