Un anno di monitoraggio microclimatico in una sala della Pinacoteca Nazionale di Ferrara: problematiche di gestione ambientale e conclusioni

The article deals with the microclimate monitoring of a room in the national picture gallery of Ferrara, started in May 2006 for a term of twelve months. This work was aimed to draw a general and complete picture of the microclimate conditions in which paintings are subjected. Two paintings on wooden tables, representing “Coronation of the Virgin” and “St. John the Evangelist”, dated XV century, have been subjected to several investigations like the study of EMC (equilibrium moisture content) and its variations during all months of the year, and illuminance levels on pictorial surfaces to evaluate the suitability of lighting system of the museum. Solutions are suggested to create a suitable environment for the good conservation of works of art
