“…A recent example focused on different Moroccan climate zones-Ben Guerir, Agadir and Tangier-can be found in [46]. As can be seen in Figure 5, we selected the DesignBuilder software package for building modeling and analysis; we also used the EnergyPlus software package for simulation purposes [47]. This software package is widely used as a simulation tool for energy optimization of buildings [48].…”

The trend in energy consumption, with a particular focus on heating and cooling demand, is an issue that is relevant to the promotion of new energy policies and more efficient energy systems. Moreover, heating and cooling energy demand is expected to rise in the next several decades, mainly due to climate change as well as increasing incomes in developing countries. In this context, the building sector is currently a relevant energy-intensive economic sector in Morocco; it accounts for 33% of the country’s total energy demand (as the sector with the second highest energy demand, after the transport sector), with the residential sector accounting for 25% and the tertiary sector accounting for 8%. Aiming to reduce energy dependence and promote sustainable development, the Moroccan government recently issued a comprehensive plan to increase the share of renewables and improve energy efficiency. This strategy includes novel thermal building regulations promoted by the Moroccan Agency for Energy Efficiency. This paper analyzes the thermal behavior and heating-cooling energy demand of a residential building located in Tangier (Morocco) as a case example, based on the country’s new thermal regulations and considering specific climatological conditions. A comparison with common Moroccan residential buildings as well as with those in nearby countries with similar meteorological conditions but significant differences in terms of energy demand regulation and requirements, such as Spain, is also included. Simulations were carried out using the DesingBuilder and EnergyPlus Software packages. According to the results, the last building thermal regulation requirements in Morocco need to be revised and extended in order to achieve the energy efficiency objectives established by the Moroccan government for 2030.

“…In the same way, Baghaei Daemei et al [43] examined the single-side and crossventilation systems on a residential building in Rasht. They indicated that the natural ventilation is influenced by the ratios of the wind area to the height and length of the building and the ratio of the opening to the room length.…”

Today, renewable resources and the crucial role of passive strategies in energy efficiency in the building sector toward the sustainable development goals are more indispensable than ever. Natural ventilation has traditionally been considered as one of the most fundamental techniques to decrease energy usage by building dwellers and designers. The main purpose of the present study is to enhance the natural ventilation rates in an existing six-story residential building situated in the humid climate of Rasht during the summertime. On this basis, two types of ventilation systems, the Double-Skin Facade Twin Face System (DSF-TFS) and Single-Sided Wind Tower (SSWT), were simulated through DesignBuilder version 4.5. Then, two types of additional ventilation systems were proposed in order to accelerate the airflow, including four-sided as well as multi-opening wind towers. The wind foldable directions were at about 45 degrees (northwest to southeast). The simulation results show that SSWT could have a better performance than the aforementioned systems by about 38%. Therefore, the multi-opening system was able to enhance the ventilation rate by approximately 10% during the summertime.

“…The aerodynamic design is aimed at solving the problem of optimizing tall buildings in order to improve the structural sustainability against winds. It can be argued that wind force has a decisive role in the design of the tall buildings, even more important than the earthquake loads in some cases (Baghaei Daemei, et al, 2016;Parker and Wood, 2013). Approaches to designing tall buildings in order to control the vibrations induced by wind force can be divided into three main groups: architectural design approach, structural approach, and mechanical approach.…”

The study of wind behavior around tall buildings is a critical issue in architectural and structural design. Therefore, Tall modern buildings are extremely sensitive to the wind. Thus, the assessment of wind loads to design these buildings is essential. Monitoring the wind, which is forcing extraordinary tall buildings is highly challenging. By looking at recent constructions in Iran, it is obvious that despite the fact that constructing tall buildings is spreading, there is less concentration on environmental factors such as wind's aerodynamic. The purpose of this study is to introduce a theoretical framework. Hence, by using CFD simulation, investigating on wind speed in various regions of the tall-triangular building have been focused. Finally, Autodesk Flow Design 2014 software is utilized to present a CFD simulation of a building model with a triangular footprint, Rounded Corner aerodynamic correction, and Set-back aerodynamic form. These simulations have been looking forward to finding out about how can aerodynamic forms affect pressure zone reduction in buildings and reduce wind flow pattern in urban regions.
