Subject fundamentals

As defined in 1987 by the World Commission on Environment and Development (WCED) established by the United Nations in 1983, "Sustainable development (sustainability) responds to the needs of the present without compromising the ability of future generations to meet their own needs. The concept of sustainable development has its limitations; not absolute limits, but imposed in the use of environmental resources by the present state of technological and social organization and the capacity of the biosphere to absorb the effects of human activities. A process in which the use of resources, the direction of investments, the trajectory of technological progress and institutional changes all contribute to increasing the possibilities for responding to the needs of humanity; not only for today but also for the future, giving priority to the needs of the poor of the world."

Chemistry, intended as the science of matter and its transformations, plays a central role in this passage and acts as a bridge between physics, the science of materials and human sciences. The course introduces the designer to a more aware level of sensitisation of environmental problems and of sustainability of the productive processes and the materials implied in these, proposing a scientific and technological reference cultural background from which the designer can infer versatile tools to approach the environmental problem.
What is proposed here is a course organised as a culture course on the matter, in its various divisions (atoms, molecules, extended phases) and aimed at creating a link between the microscopic and macroscopic worlds to supply the bases for a comprehension of the matter itself and of the phenomena on which technologies and processes are based, in a viewpoint of global sustainability.
It lasts for six months and is held in the 1st year, 1st teaching period.
Expected learning outcomes
Awareness of the problems of (eco)sustainability of the main processes of production/transformation of the materials used. Ability to dialogue with other technical-scientific cultures for the selection of processes/products that are more suitable in view of a design able to unite creativity, innovation and reduction of environmental impact.

The skills that we intend to provide also aim at transmitting understanding of the design process to the scale of the product. We highlight the ability that the student must acquire to face up to a wide range of problems, of design and process, aimed at defining a good, correct and expressive product, through the knowledge and skills listed here below:

- Knowledge of the field of materials;
- Ability to make decisions in the awareness of one’s own role and responsibilities;
- Ability to collect, analyse and interpret information from the context elaborating them independently;
- Ability to manage time and resources;
- Ability to reflect on the ethical, social and cultural themes linked to them;
- Ability to interact with the various cultures, disciplinary areas and professionalisms that design connects;
- Ability to work in mono- and multi-disciplinary teams;
- Ability to present one’s work in public in Italian and English;
- Opening to innovation, interest for the multidisciplinarity and for the continual updating of one’s own knowledge.
Prerequisites / Assumed knowledge
Basic knowledge of mathematics and physics.

Assessment and grading criteria
Course attendance is a condition to be able to positively develop the activities included. The level of learning will be monitored in an ongoing way; the ongoing results will go towards the final judgement (expressed with a single grade), based on the presentation and discussion of a written and graphic exam and an interview.
