Description

The Built environment is our home, but it is also a major driver of environmental impact. The European building sector consumes a staggering 1,070,000 ktons of material annually (Circular Building Coalition, 2023). Growing urban regions and consumption patterns combined with an extractive and wasteful economy create many adverse environmental impacts both inside and outside of our human habitats. Our linear economy is at the root of these challenges: core to this economic model is a fundamental disconnect between how we live our lives and do business, and what this means for the natural ecosystems that allow us to live happy, healthy sustainable lives. 

In 2004 it was estimated that at the current rate of mining, we are left with 32 years of copper, 23 years of tin, and 21 years of lead (C.O’Donnell, D.Pranger). The excavation, production, and transportation of all these materials emit vast amounts of carbon. So much so, that if we keep constructing buildings in the same manner as we are now, we will pass our carbon budget for remaining within the 1.5C scenario as defined in the Paris-Agreement. With raw materials becoming scarce and the urge to reduce the carbon intensity of the materials used for the construction of new buildings the call for different design practices is bigger than ever. In the near future, carbon budgeting, recycling and reusing will become an inevitable part of how architects, designers, and engineers construct the built environment. 

The Carbon-Based-Design Seminar focuses on integrating different parameters into design practices. Besides focusing on esthetical qualities and user demands you will also have to design within a set amount of carbon that can be emitted during the construction of your project. In several short design sprints students are encouraged to reduce the environmental footprint of their design to fit within the amount of CO2 that is still left to be emitted. 

In these sprints we will explore the influence of secondary material use, reduction of highly impactful materials, and other design parameters (such as different typologies or reducing unnecessary components) that will influence the carbon emitted during the construction of a building. Students will dive into several frameworks, tools, and methodologies which help drive long-term, meaningful sustainability progress and avoid unintended consequences and burden shifting.

Learning Objectives

At course completion the student will:

  • Understand the basics of the circular economy as it relates to the urban context and the built environment, including potential applications and their limitations;
  • Be able to map the material flows and their embodied carbon through the lifecycle of a building project
  • Be familiar of the environmental impact caused by analysed materials and how to design for reducing it;
  • Be able to bring these tools into practice
