Assessing Urban Environmental Sustainability by Means of Indicators: The Case of the Heritage Buildings

2002

Man in developed countries is looking for new and more suitable paradigms of a correct evolution, founded on an improved level of quality of life, on a pollution-free environment and on the availability of rising amount of time to be spent in pleasure and cultural activities.

IAQ monitoring in heritage buildings

2005

Heritage buildings often operate in free conditions, as they are not equipped with HVAC systems. This calls for the interventions of proper measurements with the aim of monitoring and controlling indoor physical parameters. As matter of fact, the control of indoor conditions in museums is of paramount importance for the proper preservation of artefacts. Moreover, in such buildings another requirement should be achieved, that is the maintenance of the comfort and safety conditions for visitors. In this work the results of a survey carried out on a hall of a historical palace to estimate the people occupancy by making use concentration of CO(2) are reported.

STRUMENTI E METODI PER INTEGRARE GLI ASPETTI AMBIENTALI NELLA MANUTENZIONE DEL PATRIMONIO ARCHITETTONICO

2022

La corretta e costante applicazione della manutenzione può assumere un ruolo chiave per garantire la qualità del patrimonio costruito e il soddisfacimento delle più recenti classi di requisiti ambientali. A tal fine, è necessario che le strategie che guidano la programmazione delle attività di manutenzione siano modellate sulle caratteristiche del manufatto in esame. In Italia una larga parte degli edifici risulta edificata prima del 1946 e, molti di questi seppur non strettamente tutelati dalla legge, possono presentare rilevanti caratteri morfologici o costruttivi che vanno opportunamente conservati. La manutenzione, condotta in un’ottica sistemica e multiscalare, comprendendo interventi …

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.

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…

Energy and environmental assessment of heritage building retrofit

2020

In the transition to a low-energy economy, the building stock renovation should address the reduction of the environmental impacts, by means of suitable energy retrofits oriented to meet current energy efficiency regulations, construction guidelines, and standards on comfort and operation. With regard to the historic segment of the building stock, suitable refurbishment policies are needed to avoid the loss of their heritage values, even if this is a complex issue requiring interdisciplinary approaches, dedicated diagnostic procedures, and specific tools. In this paper a suitable method for energy and environmental assessment specifically devoted to historical building retrofit, following a…

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…
