Climate adaptation of design scheme for energy-conserving high-rise buildings—Comparative study of achieving building sustainability in different climate scenarios

Given the climate-sensitive interactions between buildings and the immediate environment, an insight into the impact of design parameters on building energy performance under specific climate environments is crucial for the sustainable development of green buildings. The following study imparts a distinctive view of the performance-based effect of architectural and engineering design parameters on high-rise office buildings by exploiting the advantages of climatic features in different climate environments. Therewith, the study identifies and compares the major sensitive design parameters on the energy performance of high-rise buildings in different climate contexts. Furthermore, the most applicable passive strategies to attaining stipulated building sustainability criteria are established. The results indicate that the energy performance in a certain climate environment is highly sensitive to the design characteristics, such as plan ratio, core position and atrium effect. In a cold climate environment, a high-rise building with a rectangular building plan (plan ratio = 1:1.44, with vertical split-core in the absence of an atrium), satisfies the Passivhaus engineering criteria on air-tightness and fabric insulation; and adopts double-glass curtain walls, presented the best energy performance. Whereas, a square building plan (with vertical split-core and no atrium) that complies with the air-tightness and fabric insulation criteria under Passivhaus engineering standards, minimizes east- and west-bound window exposures, and adopts double-glass curtain walls exhibited the best energy performance in the hot climate zone. However, it requires renewable energy systems as an additional energy source to attain the stipulated building sustainability criteria.
