Abstract

What does the fourth industrial revolution mean to the design and engineering of facades of the future? We are experiencing a global technological revolution and the ‘archaic’ construction sector is at a crossroads. The global challenges of climate and the environment in combination with rapid urbanization calls for radical change in a highly fragmented sector, where definitions of disciplines and construction practice do not readily lend themselves to swift transformation and innovation. Technology and engineering may offer some of the possible solutions, but the challenges of the necessary transformation are formidable and will require new mindsets and new capabilities.

In this context, there is a fundamental difference between what we refer to as digitalization and computation. The façade engineer of the future will need to master computation and information technology in order to integrate complex technology, while still considering a multitude of design parameters pertaining to architecture, constructability, performance, cost and value. The integration and exploitation of computation throughout the different stages of design, delivery and operation of buildings will offer vast advantages through virtually unlimited optioneering, optimization, and hence potential gains in productivity, performance, and quality.

In an almost Darwinian sense, we are likely to see that those professionals and corporations that are able to adapt to and - to some extent - drive these changes will thrive while those that are not willing or able will increasingly struggle and fall behind. The paper outlines the promise of ‘I4.0’ and discusses through examples some likely implications on the practice of design and delivery of architecture and building technology with special focus on facades. Topics covered include automation of design and fabrication, parametric design, additive and subtractive manufacturing, optioneering and optimization, performative architecture, multiparameter decision-making, dynamic façades and transformable architecture, artificial intelligence, digital twins, augmented and mixed reality, robotics and drones.

Introduction

The Fourth Industrial Revolution – Frequently referred to as Industry 4.0 – is a term which takes on different meanings depending of context. Digitalization, computational power, connectivity, and automation are
