Abstract

The control of the microclimate inside a building hosting cultural heritage is an important issue and the management should be carefully performed. Moreover in spaces like churches frequented by people also comfort, indoor air quality and fire safety have to be considered. From the point of view of good engineering practices, the values of the aforementioned parameters have been suggested in recent legislation and in national standards and general information can be found in technical literature. Seldom the con-servation needs of cultural heritage conform to predetermined standards, and therefore suitable environmental conditions have to be determined on a case-by-case basis. Moreover, sometimes the installation of an heating system controlling the temperature and/or the humidity values have led to results opposite to what was intended because of the complete modification of previous conditions. In this context in the last years the direct combustion radiating heating diffused in the historical churches thanks to the clear advantage in the climatization of wide vol-umes. The aim of this paper is to present, improvements and guidelines for the installa-tion of radiating systems direct combustion. Some relevant topics, like air temperature variation and ventilation rate, fire protection, are discussed. Experimental data coming from literature and collected in an historical church used as test case during the winter period are presented.
