Data-Driven Analysis of Spatial Patterns through Large-Scale Datasets of Building Floor Plan

CAADRIA 2021 Paper, Honkong, China (Online)

This paper introduces a unique quantitative analysis method and results that are differentiated from those in existing studies. We analyzed five types of information in floor plan images: the silhouette, number of rooms, room area, and direct and indirect room connectivity. Furthermore, the analysis used a large-scale apartment unit dataset consisting of 33,892 units. We present convincing and objective spatial pattern analysis results of Korean apartments by quantitatively analyzing a large-scale dataset. It is expected that the analysis results will clarify the characteristics of the residential environment of Korean apartments. The results suggest that changes in lifestyles lead to the modularization of bedrooms, increased numbers of private bathrooms and balconies with corridors as junctions, and the diversification of room layouts.

Multi-Objective Pareto Optimization of Tensile Membrane Architecture for Energy Harvesting

applied sciences 10.18 (2020): 6231

With the global concern about rising greenhouse-gas emissions due to fossil-fuel-based power generation, electricity production using eco-friendly energy sources is becoming increasingly important. Conversion of vibration into electricity is characterized mainly by electrostatic, electromagnetic, or piezoelectric transduction mechanisms, which can be used to generate electricity through a variety of methods. The tensile membrane architecture (TMA)—the means of electricity production investigated in this study—is an architectural structure that is classified into the same category of vibration sources as buildings and bridges, but has not been utilized previously for vibration-generated electricity. The objective of this study is to determine which TMA geometry yields optimal electricity production and stability in a specific region. The developed optimization technique can help future researchers to select the TMA type and material for specific areas and evaluate the suitability of different areas for energy.

Sliced Chair

inspired by Kokoon Chair (by Karim Rashid)

Sliced Chair is made of clear acrylic.
It was cut in one piece by the laser cutter.
Then, bent with a hot gun and a 3d printed mold.

The best location and widths of joints of back
and legs were optimized by numerous tries.

If the joints are too narrow, they could not support
the weight of back but else the chair geometry
did not look good with thick joints.

This blueprint is the best looking scale and
able to support the weight itself.
