Digital to Physical: Comparative Evaluation of Three Main CNC Fabrication Technologies Adopted for Physical Modelling in Architecture

The objective of this experimental study is to investigate and systematise data regarding the production issues and limitations of Computer Numerically Controlled fabrication technologies typically adopted for physical modelling in architecture. This study also aims to observe the value of potential feedback to the design process from different types of digitally fabricated architectural models. This experimental research systematically explores digital fabrication as a computer-aided modelling tool using two international architectural competition projects as case studies: the design of a skyscraper and relocatable schools. Developed by the authors especially for this research paper, each case study acts as a test bed to compare and evaluate digital production techniques adopted for physical modelling in architecture. Designs go through a process of refinement using CNC fabrication as an integral part of the design process. Each step in the process is closely evaluated as to its effectiveness according to a matrix of feedback criteria.

Hybrid environmental-media facades: rationale and feasibility

ABSTRACT It has been demonstrated that kinetic sunscreens linked to intelligent building systems have the potential to improve the energy performance of large-scale public and commercial buildings. However, there has been minimal uptake, primarily due to the capital and maintenance costs. This study proposes that costs can be offset through adding value by repurposing the sunscreening system as a low-resolution media screen. To evaluate the feasibility of this hybrid environmental-media facade concept, physical prototypes has developed and calibrated to real-time simulation and control software; and two case studies were undertaken to assess the physical and economic feasibility. This article introduces the rationale for a hybrid façade, documents the prototypes and case studies, and outlines further work on control systems for a truly smart building façade.
