1 La Comunità Sostenibile: una soluzione partecipata per gli obiettivi della Direttiva Clima Energia. Nuove opportunità di coesione sociale e di sviluppo della sussidiarietà Il ruolo della formazione la responsabilità professionale Angela Poletti Politecnico di Milano

2 Metodologie UNFCCC (United Nations Framework Convention on Climate Change) Greenplan Scuola americana Usi del suolo Attività e sviluppo sostenibile Mantenimento di foreste esistenti Riforestazione Forestazione di suoli prima non forestati Valutazione dello stock di carbonio nelle foreste Equazioni di tipo allometrico(da studi sul campo di alberi in contesti urbani) Simulazione crescita del singolo albero Evoluzione e sperimentazioni ulteriori dell approccio impiegato da Greenplan

3 Greenplan Carbonio immagazzinato e rimosso Crescita alberi Specie Età Stato di salute Rimozione inquinanti Deflusso superficiale Dati di contesto Velocità di deposizione Concentrazione inquinante in atmosfera Dati di contesto Estensione suoli permeabili/impermeabili Grado di impermeabilità suoli

8 Gli esiti sul territorio

9 Strumenti operativi Protocollo sistema di valutazione strutturato del grado di sostenibilità di un intervento edilizio (nuova costruzione o ristrutturazione dell esistente) e della trasformazione del contesto territoriale Strumento di progettazione e di verifica (o controllo)

10 Contributo alla ricerca Creazione di uno strumento Scientificamente rigoroso analisi dei metodi di calcolo applicati nei contesti specifici delle varie discipline coinvolte analisi dei protocolli di valutazione Fattibile valutazione esaustiva ma non ridondante delle prestazioni dell intervento edilizio Tecnicamente funzionante supporto informatico di facile utilizzo Integrabile

11 Caratteristiche la logica Valutazione integrata analisi svolta sulle diverse aree tematiche messe a sistema mediante l attribuzione di pesi, al fine di ottenere un risultato di sintesi prestazionale Stima dei pesi Gli intervalli dei valori assegnati ai pesi sono vincolati in funzione dello stato di fatto dell area oggetto di trasformazione (analisi preliminari)

12 Caratteristiche gli strumenti Utilizzo di sw già esistenti Analisi chimiche del suolo, calcolo delle dispersioni termiche, analisi di fattibilità degli impianti a energia rinnovabile, etc. Supporto informatico Il protocollo si presenta come uno strumento informatico di intuitivo utilizzo, supportato da database e articolato secondo le fasi cronologiche del progetto

13 Struttura e punteggi 8 Tematiche o aree di valutazione (Qualità ambiente interno) 29 Categorie (Areazione) 125 Criteri (Efficacia dell areazione) Somma dei pesi punteggio per tematica Somma dei pesi punteggio per categoria all interno di ciascuna tematica Somma dei pesi punteggio per categoria all interno di ciascuna categoria
