To address the problem of global warming, efforts are being made worldwide to reduce carbon emissions. As part of these efforts, a plan for energy savings at the national level has been established. Large cities in each country are major energy consumers. In addition, architects of metropolitan high-rise towers, which are also major energy consumption sources, have committed to establishing institutional mechanisms to reduce the energy consumption of such buildings. However, designs that consider energy performance have been limited to the introduction of conceptual technology. Energy-saving plans considering energy performance are generally established through heating, ventilation, and air-conditioning (HVAC) systems only after the design of the tower is determined. By analyzing the mass form determinants, except those for HVAC, in designing a tower, this study analyzed the correlation between the mass form determinants and energy performance of the tower, allowing designers to consider energy performance from the early design stages. This study then attempted to analyze design strategies for efficient energy reduction, without relying on HVAC, in the phases prior to deciding on a design. In addition, this study attempted to transform the correlation into an equation using the typical floor plan, window area ratio, skin size, floor area, volume, floor height, story height, and aspect ratio, which determine the mass form in the early phase of design. By developing objective design indicators for energy performance based on this equation, this study could be used as basic material for rating the quality of energy performance-based designs, thereby contributing to the growth of low-carbon-footprint green construction. |
