• Heightening population density and expanding urbanization has increased the need for constructing high-rise buildings due to land shortage. Many efforts have been done to design or retrofit high-rises in an energy efficient and sustainable way to decrease their significant environmental impacts. A high number of studies have been conducted on reducing the energy demand or carbon emission of High-Rise Buildings (HRB). This paper presents a review of 48 previous studies regarding energy and carbon performance of HRBs during 2005–2020 in different climatic contexts. Results showed great potential of reducing energy consumption of high-rises by enhancing envelope design parameters (up to 78.9%), optimizing plan layout (up to 17%), and utilizing natural ventilation (up to 45%). Furthermore, reviewed researches proposed a number of methods to reduce operational (up to 25%) and embodied (up to 60%) carbon emissions, mostly by enhancing envelope heat transfer coefficient and using recycled materials, respectively. Efforts have been also made for achieving net-zero energy in high-rises by integrating renewable energies. Eventually, research gaps and future study potentials are presented. Categorized results of this review would help designers to identify the most influential design parameters of high-rises regarding energy consumption and carbon emission. •This paper presents extensive description regarding energy efficiency and carbon emission of high-rise buildings (HRBs).•Useful energy-efficient design or retrofit strategies are categorized in six main sections.•Promising results regarding energy and carbon emission reduction are obtained in each category.•The most investigated parameters and metrics, as well as useful software in each category are presented.•Research gaps and future study potentials in the scope of HRB energy efficiency are suggested.
