The Toolkit is an innovative interactive bottom up and participative (living lab) programme for training and education of technicians and students, with suggestions in management and experience sharing. A selection of best practices will provide useful information to implement Passive Solution Design in order to reduce energy consumption, improve building envelope performance and promote a new environmental conscious human behavior.
• Abacus of existing relevant Mediterranean building passive renovation solutions
With the aim to explore the most innovative experiences related to the renovation of higher educational buildings in the Mediterranean Area, a deep research in the literature was carried out investigating the most recent architectural interventions on university buildings. Based on a defined methodology, case studies were organized to highlight their innovative features, in order to be compared and evaluated. The survey permitted to define an Abacus of innovative solutions for the renovation of higher educational buildings in the Med Area.
The research selected, analysed and catalogued a total of 18 case studies, concerning 9 university complexes built from scratch and 9 cases of energy modernization and restructuring.
Based on the common methodology, the analysis of the single projects gave the possibility to compare them according to a list of identified indicators on energy performances. A comparative critical analysis of the case studies relating to the “Renovation” and “New construction” projects was conducted to highlight which were the best and worst projects, according to the different indicators analysed.
Using all the data, it was possible to define a final classification of the projects in terms of cost-efficiency, both in the case of renovations and new construction.
On the basis of the analysed case studies, but also on the long years of design and the team’s research experience on sustainable architecture, it was possible to define an Abacus of traditional/innovative solutions for an energy efficient refurbishment of high educational buildings in the Mediterranean area. As an easy-to-use tool, the Abacus is a list of traditional/innovative technologies organised according to the building elements composing the envelope and the building service system.
• Innovative scenarios for the energy renovation of high educational building in the Med area
A range of innovative scenarios, was defined, for the building energy renovation, from the passive/low tech to the high tech.
The design process of innovative scenarios and use cases started from the data retrieved from the energy audit performed within the project framework, which were inserted in a digital model of the pilot building (BIM). Virtual simulations on the building energy performances have been performed and compared with the audit data. Exploiting the abacus of innovative solutions, 5 scenarios of intervention have been defined (from passive/low-tech to high-tech) and tested in the virtual model. The intervention scenarios are going to be evaluated in their cost-effectiveness and technical feasibility.
To approach the matter, the research team adopted a participated design process, which make possible to taking into account the contributions of stakeholders involved in the local and cross-border Living Lab.
• Optimal passive building measures for the renovation of high education buildings
The team finally did exploit the results of the previous activities, from the analysis of the case studies and the definition of the abacus of innovative practices to the evidence-based design process, supported by simulations, for the definition of the innovative scenarios and use-cases on the pilot building.
Such activities led to the identification of the optimal passive retrofit measures, and their replicability potential for higher education buildings in the Med area.
