Old buildings that represent and maintain historic values often have poor indoor conditions and energy efficiency. The aim of this work was to evaluate the influence of building structures on airtightness and energy performance of certain historic building types. In this study on-site measurements, dynamic simulation and questionnaires were used. Significant differences between the levels of the airtightness of the historic houses exist in the studied region. No statistically significant correlation was found between the structure types and the envelope tightness.

Effective conservation of historic buildings subject to monumental restrictions is realized through a re-use for modern functions. In fact an attended and therefore ventilated and climatized building can be maintained in thermo-hygrometric conditions suitable controlled in order to avoid the occurrence of mold. Often only the use can justify a timely and adequate maintenance. Although the sustainability of the requalification requires acceptable management costs and therefore a limitation of the energy consumptions which must be comparable with those today prescribed for new buildings.
