Considerations Regarding the Solutions for Heating and Cooling of Cult Buildings

Abstract

Abstract Religious art, expressed through the architecture and painting of churches, is subject to the action of time, requiring preservation of the architectural and artistic heritage throughout their existence by providing adequate microclimate parameters. Functional and constructive particularities of cult buildings – large volumes constructed, high thermal inertia of the envelope elements and periodically occupied spaces with variable occupant – influence the conditions of conformation and operation of the heating and air conditioning systems. The determination of the calculation parameters and the conformation of the installation systems must take into account these particularities and consequences leading to the necessity to provide some installations with low functional inertia. The report presents an adequate method of calculation based on the thermal balance of the air in the enclosure and the envelope space, under the conditions of cyclical operation and with limited duration of the installations. The paper is within the thematic context of the doctoral thesis “Energy efficiency solutions for heritage buildings”
