“…In the stage of architectural scheme design, building orientation is also an important factor affecting building energy consumption, which is directly related to lighting, ventilation, solar radiant heat, and so on [40]. Considering the shape symmetry of the three typical models, when the building orientation changes, only the angle changes within a certain range need to be considered.…”

Under the impact of COVID-19 and the needs for urban expansion, a large number of outpatient buildings have been rapidly constructed, but the problem of high energy consumption has always been ignored. There is a lack of research on the adaptability of building shape in different climate zones. Many studies have shown that a reasonable shape in the early stage of design can significantly reduce the energy consumption of buildings. Therefore, it helps if architects quickly select a reasonable shape that can effectively reduce energy consumption. This study summarized a number of outpatient building cases in China and proposed three typical building shapes: centralized-type (Shape-1), corridor-type (Shape-2), and courtyard-type (Shape-3). The Design Builder tool was used to simulate and analyze the typical building energy consumption in different climate zones. The simulation results show that Shape-2 (angle: 0°) should be chosen in severe cold zone; Shape-1 (angle: 90°) should be chosen in cold zone; Shape-1 (angle: 0°) should be chosen in hot summer and cold winter zone; Shape-1 (angle: 60°) should be chosen in hot summer and warm winter zone; and Shape-1 or Shape-2 can be chosen in warm zone. The results of this study can provide suggestions for the energy saving design of outpatient buildings in China and other areas with similar conditions. The result can help architects make rapid shape selection in the early stage of design.

The building architecture significantly affects the energy consumption of buildings. In this paper, we study the effect of using U-shape exterior walls on energy consumption. The main target is to evaluate the impact of this parameter on heating and cooling loads for a small building model in Tetouan, Morocco (an administrative building divided into 2 zones, the effective area is 27 m2). In this context, a parametric study was carried out by the TRNSYS software 18, in order to evaluate the efficiency of using this form of exterior walls according to two selected criteria: the orientation of the exterior wall and the depth of the U-shape. More precisely, five values of the U-shape depth were studied for each orientation (South, North, South-east, and South-west), in six climate zones in Morocco presenting different climate conditions. In this sense, 126 simulations were done to have as a result the heating and cooling load for each scenario. The results showed a significant difference in the total load of the building model using different depths of the U-shape exterior walls in different orientations. We found that the U-shape parameter modified in the exterior walls is more efficient in zones characterized by a cold to moderate climate, namely, Ifran, Rabat, and Tangier (the maximum reduction of heating and cooling demand varies from 3.6 to 14% depending on the climate zone). Also, a maximum reduction in the total heating and cooling consumption is noticeable in zones with a hot climate which fluctuates between 1.9 and 3.1%.

“…While, although there are some differences between different cities for the wall with different heat storage coefficients ( L w and H w ), its advantages can be ignored compared with the insulation layer location. As for factor B , it’s lower the more energy-saving for cities with high heating demand, while it is obvious for cities with high cooling demand that the higher energy consumption [ 76 ]. Which makes further explains that the lower B ( K wall ) can effectively block the heat transfer from indoor to outdoor, and increase the cooling load despite the reduced heating load.…”
