Urban Planning and Valuation

The quality of extra-virgin olive oil (EVOO) is strongly correlated to the fatty acid alkyl esters (FAEE) content. High storage temperature leads to degradation of positive oil attributes in the long term, while low temperature develops rancidity quickly, thus reducing the consumer’s acceptance and, therefore, the shelf life of EVOO. In Calabria, there are many traditional olive mills, yet only few are utilized nowadays. This is mainly due to the low building performance—in particular to the temperature control inside the oil storage area. This paper illustrates the thermal analysis carried out on a famous historical olive mill located in Lamezia Terme, the best agricultural land in Calabria. A thermal retrofitting assessment was conducted, and eight different passive strategies were evaluated to improve the sustainability of the buildings.
