Research Summary: Due to the ever growing trend of urbanization and population growth, the construction of high-rise buildings is inevitable and will also continue at an ever increasing pace. However, typical high-rise buildings (the traditional template of a rectilinear, air-conditioned box) are not energy efficient in many aspects of their design. In this research the impact of architectural design elements on building energy performance will be studied in three climate types, temperate, sub-tropical and tropical. The exterior envelope, building form and orientation, service core placement, plan layout, and special design elements like atria and sky gardens are the subject of investigation. This study found that a double-skin façade with automated blinds and operable windows besides a narrow floor plan, the correct placement of core services in regards to solar heat gains, and the application of vertical shafts like atria, which bring daylight and natural ventilation deeper into the plan, are the stra tegies that effectively can provide energy savings for tall buildings. However, when the building has this potential to use energy efficient design strategies, the real performance depends on how the building is used by the occupants. Designers should therefore take user behavior into account during the design stage.

Research Methodology: This project comprises two major parts. For the first step, in order to find the energy efficient design solutions for high-rises, twelve case buildings will be selected with different degree of sustainability from three climate types (temperate, sub-tropical & tropical). For each climate group, there are three sustainable high-rises and one typical high rise design as a reference. Sustainable design approaches beside building-related energy performance data will be collected through a literature review and contact with the energy consultants. For the next step, in order to estimate the effectiveness of different design strategies on cooling, heating, ventilation and lighting, one typical high-rise building will be modeled (via DesignBuilder) per climate type. Afterwards, different design strategies will be added to the basic model to find the maximum energy saving. Finally the optimum design will be presented for each climate through integration of different design strategies.

Main Question: What are the design strategies that help a high-rise building to use less energy for cooling, heating, ventilation & lighting?
Design guidelines for planners and designers with the aim to reduce the energy consumption of high-rise buildings from the early stage of design.
