Abstract

According to the Global Status Report REN21 the buildings are responsible of around one third of global final energy consumption and 28% of greenhouse emissions. In the context of the European Sustainable Development Goals and the aim of the European Union at obtaining a free-carbon economy within 2050, it is necessary reducing primary energy demand and greenhouse gas emissions during operational phase of the industrial buildings, whose impact is underestimated. The paper concerns with the Tuscany’s context, characterised by an industrial buildings stock mainly built before the ‘90s with reinforced concrete prefabrication systems. All these buildings share similar architectural, structural and technological characteristics as well as common issues: structural and energy due to both external envelope thermal insulation and systems for energy supply. Moreover, the presence of asbestos in roofing elements requires urgent interventions. As clearly emerging, the integrated redevelopment of industrial heritage is an urgent topic of interest. A preliminary assessment of construction technologies, recurring characteristics and typological factors was carried out in two different geographical areas in Tuscany, leading to several statistical data used to define recurrent industrial building types. Starting from the energy requalification of a building representative of the most widespread category, the research aims at defining a methodology for multidisciplinary retrofitting to be applied also to other building types with the same intended use. The approach is based on reducing both primary energy demand and CO2 emissions. This can be achieved with energy efficiency measures addressing envelope components and more efficient systems for both heating, cooling and industrial processes using renewables for energy supply. Sensible energy savings and improvements in internal conditions can be achieved. As regards energy production, the only introduction of the photovoltaic system on the roof is not enough to satisfy the loads required by the manufacturing process on colder months.
