FROM SCAN-TO-BIM TO HERITAGE BUILDING INFORMATION MODELLING FOR AN ANCIENT ARAB-NORMAN CHURCH
2022
Abstract. One of the most significant issues in Cultural Heritage is the management of ancient buildings to monitor their state of conservation or to plan actions in their maintenance; this issue can be now approached thanks to the use of the Scan-to-BIM process. This method allows the creation of parametric models into a BIM environment, which are capable of enhancing the geometrical representation of building elements and integrating different types of data.This paper shows the results of the research activities carried out by the Department of Engineering at University of Palermo (Italy) on applying the Scan-to-BIM approach to the survey and the modelling of an ancient Arab-Norman church…
Experimental determination of natural air ventilation rates based on CO2 concentration
2009
This study reports the first results of a survey carried out by the authors on a hall used for conferences, training courses, seminars, and aimed to determine the correlation between the concentration of CO2 and the number of air changes only through natural ventilation. The assessment of ventilation rates was based on the knowledge of the indoor and outdoor CO2 concentrations and of the number of people in the hall. As it is known, the CO2 concentrations can be used as an index for the number of people present in a room and can be evaluated as a function of time by using the Meckler equation in steady-state conditions. In that case it is however necessary that some restrictive hypotheses a…
Ventilation Problems in Heritage Buildings
2007
The control of indoor conditions in heritage buildings, such as castles or museums, is of paramount importance for the proper preservation of the artworks kept in. As heritage buildings are often not equipped with HVAC systems, it is necessary to provide proper interventions and measures with the aim of monitoring and controlling indoor physical parameters. Moreover, another requirement should be achieved in such buildings, that is the maintenance of the safety conditions in presence of visiting people. This work reports the results of a survey carried on a hall of a historical palace, aimed to assess an useful correlation between CO2 concentration and occupancy levels.
