Architecture Engineering and Science

The Global Warming, Climate Change, Energy Depletion, and Carbon emissions are the greatest risks to humanity in the 21st century. Urbanization in many ways increases the lack of energy resources and demands more construction of high-rise towers for a better standard of living. Buildings are responsible for around one-third of global greenhouse gas emissions. With the emergence of the energy crisis, the rise of environmental consciousness, energy-saving measures, and sustainable buildings became a topic of attention. Due to advancements in technology, the design of high-rise buildings has come across various changes with large glass openings, sealed windows, and deep plans which increase the dependency on air conditioning systems (HVAC) thus increasing the demand for more energy consumption inside the building due to mechanical ventilation and air conditioning. In this paper, an attempt has been made to understand the strategies used for designing energy efficient high-rise buildings that can lower the heating and cooling load and thus increase the performance of the high-rise building. The research is based on a theoretical approach and qualitative analysis which is identified from the literature review and secondary case studies, Case studies selected for the study are office high-rise buildings which are sustainable skyscrapers and have achieved lower energy consumption in heating and cooling load compared to the typical office building which shows how an increase in natural ventilation and other architectural design parameters such as building envelop, form, orientation and integration technology like Building Management System (BMS) system can make it more energy efficient high rise building.
