Computation-based approaches have been flourishing in the construction industry for the past years. From experimental practices to mainstream production, usage of digital tools tends to be diverse and versatile. This is especially true for Computational Design (CD) which encompasses multiple practices, transforming the future of the industry and its stakeholders. Through the ever-increasing speed and capacity of computers, computation enables dealing with geometries and tasks which were traditionally either too time consuming or too challenging to be accomplished by human alone. However, CD is not just automating existing traditional processes or tedious tasks, it's about shifting the way we think and design. To better understand how to unlock the opportunities of CD, this chapter discusses: 1-the main subsets of CD, called parametric, generative and algorithmic design; 2 -presents CD's different toolsets and their evolutions, and finally 3interrogate how CD is integrated in practice, with its emerging roles and skillsets.
