The reduction of energy use and related emissions in the built environment is a priority for both national and local authorities. Public authorities have to manage varied building stocks with generally low budget available, thus needing to enhance their institutional capacity in the field of energy efficiency and use of renewable energy sources. This paper describes a Decision Support Tool (DST), designed for comparing a portfolio of energy efficiency and renewable energy interventions on the overall set of municipal public buildings of a given local authority resulting in an evaluation of the investment opportunities in terms of costs, energy savings and CO2 emissions avoided. The DST was co-developed, validated and tested for over 300 Municipal Public Buildings (MPB) from five Mediterranean countries (Italy, Portugal, Spain, Greece and Croatia).

La riduzione del consumo energetico e delle emissioni nell'edilizia è una priorità per le autorità pubbliche, che devono gestire stock edilizi spesso obsoleti con budget generalmente bassi, necessitando quindi di migliorare le capacità istituzionali ed incrementare l'efficienza energetica e l'uso di fonti energetiche rinnovabili. L'articolo descrive uno strumento di supporto alle decisioni (DST), progettato per confrontare un portafoglio di interventi di efficienza energetica ed uso delle rinnovabili negli edifici pubblici, fornendo una valutazione delle opportunità di investimento in termini di costi, energia risparmio ed emissioni di CO2 evitate. Il DST è stato sviluppato, convalidato e testato in oltre 300 edifici pubblici municipali di cinque paesi del Mediterraneo (Italia, Portogallo, Spagna, Grecia e Croazia). I risultati presentano la classifica degli edifici pubblici in base ai criteri considerati effettuata nella regione di Leziria do Tejo in Portogallo ed illustrano i vantaggi e le limitazioni dell'utilizzabilità dello strumento identificati dagli utenti.

Abstract
The reduction of energy use and related emissions in the built environment is a priority for both national and local authorities. Public authorities have to manage varied building stocks with generally low budget available, thus needing to enhance their institutional capacity in the field of energy efficiency and use of renewable energy sources. This paper describes a Decision Support Tool (DST), designed for comparing a portfolio of energy efficiency and renewable energy interventions on the overall set of municipal public buildings of a given local authority resulting in an evaluation of the investment opportunities in terms of costs, energy savings and CO2 emissions avoided. The DST was co-developed, validated and tested for over 300 Municipal Public Buildings (MPB) from five Mediterranean countries (Italy, Portugal, Spain, Greece and Croatia). Selected results are presented for Leziria do Tejo region in Portugal, depicting a ranking of public buildings by the considered criteria. Advantages and disadvantages identified by its users and the usability of the DST are also unfolded.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
