Strengths & Limitations

Strengths

  • +Analysis of a significant number of case studies (40).
  • +Focus on a specific and trending architectural typology (tapered super-tall towers).

Limitations

The study didn't find a strong link between building function and space efficiency, which might mean other factors are more important or that the link is more complex.

Reliability & validity

The study's reliability is supported by a substantial sample size of 40 case studies. Validity is enhanced by focusing on quantifiable metrics like space efficiency and core area ratios within a specific building typology.

Think critically

How might the 'mixed-use' purpose of many tapered towers influence the optimal size and placement of the central core, and could this impact overall space efficiency in ways not captured by this study?

05

Design Principles

"Optimize building form and internal layout to maximize usable space within structural and functional constraints."

Understanding the space efficiency of tapered super-tall towers is crucial for optimizing building design and resource utilization. This insight can inform decisions about core placement, structural systems, and material choices, ultimately contributing to more sustainable and functional urban developments.

06

What This Means for Your Design

Tall buildings that get narrower as they go up are usually about 72% usable space, with the central part (the core) taking up about 26% of the space. Designers often use a central core for different uses and strong frame structures with modern materials.

How to use in your project

  • 1.Reference this study when discussing the space efficiency of your own design, especially if it's a tall building or has a tapered form.
  • 2.Use the findings as a benchmark to compare your design's space efficiency against.
