The research aims at verifying aesthetic, technical, energy, and environmental opportunities of integrating different photovoltaic (PV) roofs in the “Rustico Macchi,” an Italian heritage building that needs a deep energy renovation for hosting exhibitions and school projects. Compatibility of different PV products and technological solutions for heritage buildings are evaluated through the support of the focus groups with the local Heritage Authorities. Besides, a dynamic building energy model is created from on-site information for testing energy and environmental benefits of the various PV interventions. The results of this analysis are reported in a risk-benefit scheme that compares the following: (i) “aesthetic integration” implying a compatible visual interaction with historic shapes, characteristics, and materials; (ii) “technological integration” involving the multifunctionality of energy production and building functions; (iii) “energy integration” indicating the efficient PV integration on the overall energy consumptions, and (iv) “environmental integration” related to clean production and positive interaction between the building and the environment. The results highlight that a balance between preservation, energy production, and sustainability is still possible respecting the heritage significance of the building and its settings as well as using tailored design solutions, innovative, and multifunctional PV products.

Abstract
The research aims at verifying aesthetic, technical, energy, and environmental opportunities of integrating different photovoltaic (PV) roofs in the “Rustico Macchi,” an Italian heritage building that needs a deep energy renovation for hosting exhibitions and school projects. Compatibility of different PV products and technological solutions for heritage buildings are evaluated through the support of the focus groups with the local Heritage Authorities. Besides, a dynamic building energy model is created from on-site information for testing energy and environmental benefits of the various PV interventions. The results of this analysis are reported in a risk-benefit scheme that compares the following: (i) “aesthetic integration” implying a compatible visual interaction with historic shapes, characteristics, and materials; (ii) “technological integration” involving the multifunctionality of energy production and building functions; (iii) “energy integration” indicating the efficient PV integration on the overall energy consumptions, and (iv) “environmental integration” related to clean production and positive interaction between the building and the environment. The results highlight that a balance between preservation, energy production, and sustainability is still possible respecting the heritage significance of the building and its settings as well as using tailored design solutions, innovative, and multifunctional PV products.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
