Improving energy efficiency in heritage buildings – a case of “Palazzo Farnese”, Italy
Abstract
Historic or heritage buildings are an important component of the building stock that necessitates energy efficiency interventions. About 14% of EU27 building stock dates before 1919 and 12% dates between 1919 and 1945 (with considerable national differences). With a significant proportion of the total building stock, and high potential for energy savings or at least high enough to warrant scrutiny from an energy efficiency perspective, heritage (listed and non-listed) buildings have become a focus of special attention in Europe. The main objective of this study is to examine the potential for energy efficiency in historic buildings in Italy through the case study of ‘Palazzo Farnese’ (a 16th Century palace converted into a musuem). The key retrofit interventions considered in this study are external wall insulation, gypsum board for external walls and triple glazing. The results show that combining wall, window, and roof retrofitting resulted in a significant reduction in energy consumption. The total energy use intensity (EUI) decreased from 175.0 kWh/m2 in the Business As Usual (BAU) scenario to 151.5 kWh/m2 in the simulataneous retrofit scenario. In addition, the results reveal that wall retrofitting is the most effective individual intervention for lowering total EUI. This research demonstrated how optimal energy efficiency measures could be successfully implemented in museums while taking both conservation requirements and people's thermal comfort into account. The most influential intervention in decreasing the total EUI is wall retrofitting. The findings of this study can be useful not only for conservation architects but also for city governments and historical buildings used as museums.Citation
