The issues of the classes include design in the spirit of "zerowaste", i.e. maximum use of existing tissue and the use of secondary building materials. In the face of climate change, construction should face the enormity of waste generated by this sector. Minimizing the production of a new substance and maximizing the use of the existing substance in combination with high aesthetic values is a considerable architectural challenge.

The classes include presentations of secondary materials and logistics solutions, discussions on the challenges of reconstruction according to  zerowaste philosophy , an exercise consisting in the analysis of the selected implementation of zerowaste architecture.
