Description
The theme of the autumn 2017 symposium is "Circular Construction". This is in line with the annual theme "Circular Economy" of KIVI as a whole. Circularity is increasingly seen as a necessity, and is that right? Perhaps so, because raw materials are becoming too expensive or are running out, the costs of waste processing are becoming too high and inequality is growing between those who can and those who cannot afford a substantial environmental footprint.
Another interesting question is whether we should limit ourselves to the circularity of future construction, or whether the entire building stock should be considered a raw material for future construction.
Every building is temporary
Circularity is often associated with temporariness. Should we design monumental buildings for eternity, or should we also attach an expiry date to them? And, as Habraken suggested: the life cycle for supporting structure, facades, layout and installation can be quite different.
This brings us to the subject of policy and regulation. As with energy, regulation is indispensable in circular building so as not to depend entirely on individual interests in construction. How to force architects/contractors to seriously consider the employability of demolition waste in new construction. For example, by attaching a duty to each demolition permit to carry out an inventory of residual materials and components and making it accessible via a website.
Supply Driven Architecture
Such an approach leads to interesting challenges. For example, with regard to validation. Especially with load-bearing structures, certification will be required. Fortunately, a lot of technology is available to check components such as X-ray, ultrasound, 3D scanning and so on. For claddings, fire safety is an issue.
Finally, architects will have to start designing based on available used materials, where the design will depend on the specific supply. We call this "Supply Driven Architecture". It will require more creativity from the architect and design costs will go up as a result. On the other hand, material costs in general will go down.
The programme consists of a number of lectures of about 20 minutes, followed by about 10 minutes of space for discussion. Click on the link below for more information on the speakers and their lectures.
