Natural Ventilation and Light
As applied to high-rise buildings, natural ventilation, and light are essential for sustainable green design (Elotefy, Abdelmagid, Morghany, & Ahmed, 2015). Daylight should be avoided in constructions erected in hot, humid climates (Abdellatif & Al-Shamma’a, 2015). In addition, it is known that there is a direct relationship between the shape of buildings and the emergence of overpressures or low-pressures.
However, the existing body of knowledge does not allow for specifying the essential physical parameters of natural ventilation as applied to high towers constructed in humid regions. The issue’s core lies in the need to determine the pressure differences as applied to windward and leeward faces. Therefore, further study of wind-induced air motion and its possible importance for green design is crucial.
Green Cores
Green scores are actively used in the design, especially in city master planning. They are an important part of the radial development principle. Nevertheless, their potential as applied to high-rise buildings needs to be investigated to comprehend whether they can be used for constructing sustainable buildings and in the maintenance of comfort zones for a living (Navaei, 2015).
Greenery
Greenery is particularly important for cooling down the ambient temperature (Sharma, 2016). Well-designed green walls, sky terraces, and rooftop gardens do not only create a beautiful visual effect but also contribute to meeting the landscape requirements. Designers should consider accompanying traditional vertical coverage with horizontal planted areas.
Façade Skin
Façade skin is one of the most important factors in green design in hot, humid regions (Halawa et al., 2018). According to a case study by Yang, Yuan, Qian, Zhuang, and Yao (2018), well-ventilated designs help in energy-saving and assist in controlling the exhaust airflow. In their article titled “Summertime Thermal and Energy Performance of a Double-Skin Green Facade: A Case Study in Shanghai,” the team carries out a comprehensive energy assessment (Yang et al., 2018). The façade is a particularly significant factor as applied to glazed buildings. The research suggests that further studies are required to understand how the use of climate-sensitive regulators can help manage hot, humid climates effectively.
