Learning outcomes

At the end of the course the student will acquire: - basic information on the environmental risk to cultural property caused by physical, chemical, biological and natural factors; - basic information about environmental impact on the constituent materials in works of art; - methodologies for assessing the microclimate in indoor and outdoor environment for a sustainable protection of cultural artefacts and providing criteria and methodologies for assessing the environmental risk and vulnerability of cultural heritage at local, regional and national scale, including the impact of climate change; - criteria and methods to plan strategies for preventive conservation and to present examples of application to museums, archives and library.

Assessment methods

Oral Examination.

The final exam consists of a discussion on the topics covered in class (a minimum of 3 questions will be asked), aimed at the evaluation of the theoretical knowledge acquired during the course, the possession of the scientific language and the acquisition of an organic vision of the topics covered.
Good or excellent grades can be achieved by students who demonstrate a critical knowledge of the subject, who are able to apply theoretical concepts to practical examples, make use of an appropriate language and make well thought out connections among the different argument discussed in class.

Mostly mnemonic knowledge, limited abilities of synthesis and analysis and imprecise language lead to grades ranging from discrete to sufficient. Important gaps, inappropriate language, lack of an overview of the topics covered will inevitably lead to a barely adequate grade or to a negative evaluation.
