Abstract
Based on the monitoring campaigns, we have evaluated the indoor microclimate in a church. Most church buildings are characterised by low thermal comfort due primarily to their architecture, heating huge volume of air. The CFD tools was used for thermal comfort evaluation in case of the existing heating system during the winter season. The simulation model was validated with experimental data and it was used for thermal and air velocity profiles in the occupancy zone of churchgoers. The aim of the paper is the study the feasibility of maintaining the heritage values of the churches while achieving the significant improvement of the thermal comfort.

From the viewpoint of thermal comfort, more research has to be performed in order to rate the human thermal comfort in the church heated with static heaters and underfloor heating system
Summary
The energy cost for heating large space, especially churches is quite high. Aside from the high energy cost that the heating system generate, there are other problems in the church when is heated during the winter. In order to heat the interior of the church for the daily mass is used a hot water static heaters (Tsupply = 900C, Treturn = 700C), introducing abrupt variation in temperature and more importantly, in the relative humidity of the indoor air. These variations have been known to cause damage to the church buildings and its cultural heritage patrimony. These variations have been known to cause damage to the church buildings and its cultural heritage patrimony. [1]
