Integrated ecosystem design: An evaluation model to support the choice of eco-compatible technological solutions for residential building

The technological components regarding building cladding are designed for ensuring thermo-hygrometric comfort conditions within habitable spaces and realising smart buildings. Often the solutions adopted are identified referring only to the characteristics of mechanical and energy materials without considering the ecological-environmental properties in an urban context. Thus, it is appropriate to choose technological components not only according to material type, but also ecological aspects pursued through presence and/or structured integration of natural elements. The technical-design forms based on building-nature integration allows, on one hand, the sustainable soil use with multiple benefits (ecosystem services) that natural systems produce, on the other hand, the identification of technological solutions sized referring environmental quality levels achieved through appropriate natural species use. In this way, it can be obtained lower buildings investment and maintenance costs, and greater energetic-environmental benefits. So, it is proposed an evaluation protocol for settlement transformation interventions structured considering environmental effects obtained with Nature-Based Solutions (NBSs) into the project. According to ecological-environmental quality level achieved with NBSs, the technological component is sized according to preliminary design parameters (noise reduction and solar irradiation degree) obtained through NBSs. The total performance level of technological solutions is expressed using Economic-Environmental Indicators. The protocol is tested on social housing case in Anagnina district of Rome (Italy).
