 Obiettivo del progetto (Objective)

'The MEMORI proposal will provide the conservation market with innovative measurement technology, improved pollution effects knowledge and evaluation and control methods for the reduction of gaseous pollutant impact on movable cultural assets, - facilitating increased and safe use of protective enclosures for cultural heritage (CH) objects located indoors in new or rebuilt buildings for collections, to satisfy demands for energy saving to mitigate climate change. MEMORI will develop a small novel portable instrument for easy combined (oxidising acidic impacts) environmental dosimetry in situ with adapted software and web page for results presentation and interpretation. MEMORI will do extensive laboratory and non-destructive field analysis of impact of indoor environments on a range of organic CH materials for the assessment of environmental quality for movable cultural assets, especially focusing on objects protected inside diverse types of enclosures. MEMORI will perform varied realistic experiments and studies of methods for mitigation of the pollution impact on CH objects in enclosures such as; use of absorbing media of different types; pollution barrier films; low emitting construction materials, and anoxic conditions. MEMORI seeks to achieve its goals by engagement of SMEs that combine expertise in marketing and consulting of conservation equipment with practical conservation experience for the benefit of conservators and stakeholders, supporting their effort to assure optimal conservation conditions for their collections. MEMORI also has significant participation of SMEs in its work with technological instruments development and presentation systems for the End users, and in the studies of mitigation methods for application with protective enclosures and accessories that these SMEs market. The basis for MEMORI is the scientific and technological excellence of research and innovation within a high quality consortium with high quality management.'

Introduzione (Teaser)

Research shows that indoor air quality (IAQ) presents a little-known risk to museum collections. Fortunately, a cost-effective system has been developed to better monitor and mitigate its impact.

Descrizione progetto (Article)

Museums commonly consider the risks that humidity, light, pollutants and temperature pose for their collections, but rarely consider IAQ.

A survey conducted by the EU-funded project http://memori.nilu.no (MEMORI) shows a general lack of awareness by museums about the dangers that IAQ poses to objects in their collections.

In response, MEMORI conducted research on the dangers of IAQ and developed an early warning tool and online system for museums to assess and reduce the impact of IAQ on their collections. The project was coordinated by the Norwegian Institute for Air Research and carried out by 14 partners, 4 subcontractors and an advisory end-user group.

Together, MEMORI partners looked at the role that organic acids (acetic and formic) play in accelerating the ageing of organic materials.

They performed experiments at laboratories, primarily testing cellulosic material, varnish, pigments (including inorganic pigments), parchments, textiles and leather.Results showed that all organic materials were impacted by their exposure to organic acids, and in some cases even at very low levels.

Next, the group looked at the use of absorption materials to reduce the presence of organic acids in enclosures. Priority was given to materials with high absorption rates at a low cost. Data from the above experiments were used to develop new recommendations for tolerable pollutant levels.

MEMORI also built on technologies from two earlier EU projects, AMECP and MASTER, to create two devices to measure IAQ.

The devices, called dosimeters, are sensitive to indoor climate, light and acidic air pollutants, and come in a permanent and hand-held form.

One university partner went further to develop a luminescence-based oxygen sensor to test oxygen in airtight enclosures.

Used in conjunction with new online software created by MEMORI, museums can now measure IAQ, evaluate its risk and decide on cost-effective mitigation strategies. MEMORI's work ensures that European heritage will be better protected, preserved and available for public viewing for longer periods of time.
