Innovative and affordable service for the Preventive Conservation monitoring of individual Cultural Artefacts during display, storage, handling and transport

The Project


The concept of Preventive Conservation (PC) of a cultural artefact is based on mitigation of the deterioration or damage due to material ageing and biological, mechanical and chemical degradation processes over time.

The degradation of an artefact depends on the environmental conditions to which it is exposed, such as temperature (T), relative humidity (RH), light (L), air pollutants (AP) – either gases such as NO2 (nitrogen oxides), SO2 (sulphur dioxide) and O3 (ozone) or particulate matter – and vibrations (V) and their synergies.


Cultural artefacts gradually adapt to the environment over time if it is maintained constant. However, their degradation rate increases considerably when they are exposed to short-term or seasonal environmental conditions (fatigue behaviour), as the effects on an artefact are cumulative in time. These changing environmental conditions are often the result of moving artworks between exhibitions, from exhibitions to storage and vice versa, or during transport for institutional loans to temporary exhibitions.

In addition, cultural artefacts can be made of wood, metal, textile, canvas, paper, ceramic, stone or glass among others, and a large number are made with a combination of these different materials. Since each material has a specific reactive behaviour as a function of environmentally-induced stresses and degradation kinetics, there is a vast heterogeneity in terms of physical and material behaviour of artefacts.


So, for an effective PC of cultural artefacts it is essential to consider the historic environmental stress and degradation kinetics of their different materials (and their synergies) and monitor the artefact at all times. However, due to the complexity and heterogeneity of the material nature of the artefacts, this requires expensive monitoring and control equipment as well as specialised personnel, out of reach for most small to medium-sized museums and collections.

The CollectionCare System

The CollectionCare project, a European Commission Horizon 2020 funded initiative, aims to develop an innovative PC decision support system targeting the needs of small to medium-sized museums and collections. It will integrate current research and technological advances in monitoring systems (sensor nodes), wireless communications, big data, cloud computing and material and multi-material degradation models into a single affordable system. This way, the CollectionCare system will be able to monitor the environmental conditions of each artefact individually at any place (on display or in storage, handling or transport), provide degradation predictions of multi-material cultural artefacts and offer suitable recommendations for their proper conservation.


To begin with, the CollectionCare system will monitor the environmental conditions with a low-cost wireless sensor node that will be attached strategically in the room, on the cultural artefact or nearby.



The data collected by the sensors will be transmitted to a cloud computing platform for Big Data using LPWAN technologies.

Then, the recorded data will be automatically stored, analysed and crossed in the cloud with advanced multi-material degradation models, as well as with the European Standards and Guidelines parameters to evaluate those data.

Later, CollectionCare system will provide degradation predictions for multi-material cultural artefacts, alarms and appropriate recommendations for preventive conservation to control and minimise their degradation, thus ensuring their preservation. This can be viewed through the CollectionCare management software web browser.

This way, CollectionCare will provide an affordable, adaptable and versatile solution for the preventive conservation of movable artwork, targeting the needs of stakeholders such as small to medium-sized museums, art galleries, libraries, archives, private collections, transport, storage and handling companies, art management software companies and insurance companies specialising in art.
