This paper presents an eco-architecture project in a public green space of the Ladispoli Municipality, located on the Italian shorelines close to the city of Rome.The purpose of the project is the creation of a multifunctional urban green space, where social relations, sports, environmental awareness education and other activities can take place in a natural context. The final aim of the project, which includes a requalification of the surrounding areas, is to obtain an ecofriendly interaction between the urban public space and the built space, with sustainable mobility principles and the conservation of the natural environment.The project offers different outdoor activities for all ages and includes the design of a building which contains two multipurpose playgrounds, a gym, supporting functions, a bar and public toilets.The building design includes a green roof, for preserving space to nature and for guaranteeing a harmonious integration with the surrounding environment.In order to enlarge the green area, to bring it up to the contiguous buildings and to create a closer connection between the housing areas on both sides of the ditch and the park itself, a tunnel for the vehicular traffic was created.The project improves the usability of the green space through the introduction of: pedestrian and cycle paths connected to the existing ones, wooden bridges, new functions and services.The distinctive feature of the whole project is an integration of different best available technologies for obtaining an optimization of the performances in terms of energy efficiency and environmental sustainability, aiming to achieve at the same time, a reduction of operating costs and the preservation of local biodiversity.

The control and improvement of energy-environmental quality in buildings are responsible for almost 40% of the emissions related to energy and processes, and are essential to achieve the commitment of the Paris Agreement and the Sustainable Development Goals (SDGs) United Nations (UN). This paper provides a support tool to planners and administrators of the territory for the identification of interventions aimed at the energy requalification of the existing Italian building heritage, mainly for residential use. The purpose of this tool is to reduce energy consumption by intervening on the building envelope with specific solutions that are identified through a matrix resulting from the study. In the first part of the study, an analysis was carried out on various factors such as the existing residential building, the building and construction types and the materials of the envelope typical of each construction period, which are critical for energy efficiency issues. In the second part of the study, the analysis of the state of the art of the insulating materials existing on the international and national market was carried out, in order to standardize the efficiency interventions of the building envelope. By exploiting the potential of the proposed matrix, and integrating it with Geographic Information System (GIS) technology, it would be possible to create a database containing information regarding the characteristics of the building envelope of the residential building stock and to identify a set of insulation interventions more suited to each specific case near Rome, Italy.

The carbon neutrality of the built environment plays a key role in fighting the climate crisis and fully realising ecological transition. In this field, the aim of the paper is to promote a new production paradigm that enables an integrated process from the design phase to the production of high-performance building components, to their “tailor-made installation” for the efficiency enhancement of the national residential building stock, reducing resource consumptions, costs, construction time and the associated environmental impact. The methodological approach is based on three key elements: digitalisation, production and performance. Recent technologies make it possible to achieve important goals, through the creation of the digital cataloguing of existing buildings, advanced dynamic simulations, improved energy performance for building stock and industrial production chain optimisation of the construction sector according to off-site construction criteria. This strategy was tested on a demonstrator building. The methodology application has made it possible to validate a catalogue of standardised insulation solutions that can be applied to 90% of the existing national building stock and that can reduce installation times by 60% and costs by around 30% compared to traditional techniques, while complying with the national requirements on thermal building insulation. The study is able to organise production according to advanced standardisation in order to meet the real demand of the market with advantages in term of production costs and economies of scale.
