摘要：The current theoretical and experimental study, on microclimate regarding wooden churches currently not listed as historic monuments, but which may in future be included among the top touristic sights of Oradea, aims to highlight the particularities of indoor microclimate in these wooden churches of the city of Oradea and the way that microclimate may be influenced by religious activities, by the number of worshippers, and by that of visitors. For the purposes of this study we used data on temperature, relative humidity and CO2 using the thermohygrometers KlimaLogg Pro and Trotec BZ30. The three wooden churches of Oradea currently not officially recognized as historic monuments but which, in future, due to their beautiful traditional wood architecture reminiscent of older churches, and to the great number of paintings and religious icons adorning them, may be deemed historic monuments, valorized thought tourism. The analysis of the obtained data reveals that there can be no optimal indoor microclimate inside these churches. DM 10/2001 recommends relative humidity of 45%-60% and temperatures between 6°C and 25°C, ideally of 25°C, so that structural damage should be avoided. On the other hand, thermal comfort for the population attending religious service or merely visiting should consist of temperatures between 17°C and 24°C and humidity of 45%-55%, in accordance to the regulations in force in Romania. In certain areas in the churches conditions do fall within the intervals recommended by the norms in force for health and hygiene and by the standards regarding microclimatic risk factors for wooden constructions. Yet this is only briefly, due to ventilation ensured by the opening of doors and windows, as well as, in one of them, by an air conditioning system.
