Environmental Assessment Tools: Toward an Interlinked Sustainable Design of Cities and Buildings. The Cases of Vado Ligure and Altare Municipalities (Italy)

The present paper aims at highlighting the connections between the environmental assessment of urban planning and building design activities at different scales. Environmental assessment is a multi-scale and inter/trans disciplinary process, which considers the city through an ecological approach. Environmental assessment includes different tools depending on the planning and design phase, with links and overlaps but also with contradictions. Four different evaluation fields are discussed - land use, water management, local resources, energy - also concerning the case of two Environmental Reports for Strategic Environmental Assessment (SEA) processes of municipal urban plans for two Italian municipalities, Vado Ligure and Altare. The analysis of case studies shows that SEA is not always an effective tool for strategic urban planning, as it includes similar assessment criteria to building scale ones, causing overlaps and contradictions.
