ABSTRACT:

There is a particular approach to the energy performance and indoor microclimate of historic build-ings. However, the implementation of energy efficiency in historic buildings is limited, given that thematerials, structure, geometry and artworks to be conserved inhibit the improvement of microclimateparameters or energy performance. The main aim of this work is to study the use of environmental con-ditioning techniques in a historic building and its impact on the conservation of artworks prior to therefurbishment project. This study describes experimental research carried out on the church of Nues-tra Se˜nora de la Merced, a historic building in a Mediterranean climate. The building was monitoredand measured to validate numerical codes using Design Builder 4.7.027 and Energy Plus 8.3. Softwarebuilding models made it possible to evaluate the implementation of different environmental techniques– passive, active and combined – in the church with a view to conserving artworks. This study concludedthat the use of passive environmental techniques does not completely eliminate the mechanical risk orbio-deterioration that are inherent to movable heritage. Proposals for the use of active systems in com-bination with passive techniques improve the initial conservation of artworks and decrease the risk ofbiological degradation. Although energy consumption is high due to the large size and thermal inertia ofthe building, consumption is considerably reduced when active and passive systems are combined.
