MACHINE-GENERATED SUMMARY NOTE :
Presently, the world is facing the severe problem of climate change. Means, the increasingly occurrence of extreme weather conditions. While some areas and their inhabitants on this planet are affected by extreme flood events caused by heavy rain falls, others suffer of unexpected heat waves and droughts (European Commision 2021). One of the main causes is the increasing emission of greenhouse gases, especially CO2, which causes a gradual rise in temperature. In the middle of the 20th century the world emitted approximately 6 billion tons of Co2. With the vast development of the industry and the growth of global markets, the emission quadrupled by 1990 up to 22 billion tons. And nowadays, the worlds emission is at over 36 billion tons per year (Ritchie and Roser 2019). The building and construction sector in 2019 accounts for 35% of the world wide’s energy consumption and simultaneously is responsible for 38% of the above- mentioned global CO2 emission (Hamilton , et al. 2020). Simply, to meet the demand of a steadily growing world population (Roser, Ritchie und Ortiz-Ospina 2019). This demand also includes an increasing exploitation of ecosystems for raw materials acquisition. In 2018 the global raw material production was at 90 gigatons. It is expected to rise to 167 gigatons by 2060 (OECD 2018), which at one point eventually will go to the landfill anyway. In Germany alone, the construction sector accounts for 60% of the total volume of waste. This is a shocking number, in consideration that 99% of the entire anthropogenic material stock is also generated in the construction sector. (Müller, et al. 2019). The take-make-dispose system of the current linear economic model is a one-way-street that not only leads to material scarcity, but also destroys ecological habitats and thus deprives humanity of its livelihood.
From an economical point of view, this extensive waste production in correlation with raw material exploitation makes it necessary to question the current linear economic model. To separate economic growth from environmental repercussions, the future model of a circular economy as a new paradigm is considered as a possible solution. This would mean a shift from “take-make & dispose” to “reduce, reuse & recycle” (Ellen MacArthur Foundation 2013).
While this puts the building and construction sector under substantial pressure, it is facing a great transformation fostered through the ongoing digitalization. The topic of the industry 4.0 is committed to fully interconnect all planning and fabrication processes as well as the entire lifecycle (Braun, et al. 2015). Focal point of this concept is the availability of all relevant data in real time (Morlet, et al. 2016). This access to real-world data can be used to efficiently influence design decisions at an early stage, when the decisions have the greatest impact on the desired outcome. The new parametric design methodology is an excellent tool for processing such data.
