Energy retrofit of rural protected buildings. The case of a new agri-food hub in a peripheral context in Milan.

The research origins in the framework of “UIA OpenAgri”, a European project of urban regeneration. The present research focuses on the renovation of two historical buildings within Cascina Nosedo (Milan). First aim of our study is to support and address the energy retrofit project of the buildings toward energy efficiency and integration of the local renewable potential, in the respect of the constraints related to the historical value of the buildings. In this framework, after a preliminary analysis of the actual conservation state, two envelope scenarios, with internal and external insulation, were developed, simulated with IESVE tool and evaluated. As main results we obtained that, for the demand side there are not significant difference in terms of energy loads on yearly basis (sum of heating and cooling loads) in the two retrofit scenarios. Several considerations on the supply side were carried out to assess the local renewable potential.
