Summary

The unique selling point of Pro-GET-onE is the distinctive integration between energy deep renovation techniques and seismic retrofitting actions: this “X-factor” aims at solving construction and safety problems within nZE (nearly Zero Energy) retrofitting, focusing on users’ priorities and expectations.
Greater efficiency, attractiveness and marketable renovation can only be achieved through a holistic and integrated set of technologies, in which all the different requirements (energy, structural, functional) are optimally managed. This is why the project idea is based on the unprecedented integration of different technologies to achieve a multi-benefit approach by a closer integration between energy and non-energy related benefits. Thus, the project aims to combine in a same holistic and integrated system based on pre-assembled components the highest performances (iii) in terms of:
i) Energy requirements – by adding (or substituting the existing with) new prefab and plug and play high-energy performing envelopes and HVAC (Heating, Ventilation, Air Conditioning) systems;
ii) Safety – using appropriate external structures to increase the overall structural capacity of the building, while supporting the new envelope consisting of timber based components for opaque parts/surfaces, and aluminum, glass, PV Photovoltaic, solar panels);
iii) Social sustainability – increasing the real estate value of the buildings and the desirability of retrofit options by providing tailored and customized solutions for users, owners, and house managers increasing safeness and minimize disturbance of inhabitants.
To sum up, the goal of this proposal is to provide the market with an innovative, yet readily implementable system for buildings’ envelope to be applied for energy, structural and user-oriented retrofit that will significantly increase the commercial value and the life cycle of buildings, will involve the users in attractive and visible solutions and, ultimately, will reduce the costs of energy retrofit options in the whole building lifecycle. This goal will be attained through the application of solutions for the building envelopes, as well as through an optimum climatic-structural-functional management, grounding on the substantial increase in the real estate value of the buildings through significant energy and architectural transformation. This incremented value will be obtained through the development and application of inteGrated Efficient Technologies (GETs) in the strategic aim of creating a new and attractive market in the deep renovation of existing buildings towards nZEBs

Work performed

Some of the WPs have already been concluded adding in this way a significant value for the continuity of the project and the research enrichment.
WP2 - concluded at M12- provided a comprehensive state of the art including the required data to achieve the cost-optimal design and implementation of the proposed system in the different case studies and to. This WP results will work as an open data-base to the remaining period of the project.
The main focus of WP3 is to provide technical and detailed studies of integrating insulation components as well as RES (Renewable Energy Sources) in relation to the external structural grid and the integration on the building envelope, considering cost and energy efficiency of each selected solution both separately and in combination. Through the continuous collaboration of the partners involved and the deep analysis and research on various solutions, first results were obtained and are still under evaluation for further implementation mainly for the case of Athens and the Mock-up.
WP4 was also completed. The aims of this WP were the evaluation of the seismic performance of the selected technologies by using advanced simulation techniques and also to find cost efficient and optimal solutions for strengthening existing residential buildings. Both timber, structural aluminium and light steel structures were analysed and implemented to provide light and optimized seismic solutions for prefab existing facades like TES facades and MORE CONNECT.
An ABACUS of different options (the façade modules) is being studied in WP5 according to the main structural frame and the residential units’ utilities. The design process is still in process nevertheless for the three case studies (Italy, Greece, Romania) there has been a preliminary analysis and is proposed a first approach for the possible verification of the abacus for each span of each building envelope.
Furthermore it is now under development a tool (an application/web site) that will translate the design process into a common practice and will be user friendly. These will be connected with energy performance indicators, economic payback projections, material-colour variations and possible suppliers
WP6 is focusing on the evaluation of the integrated design and technologies proposed for the GET system. In detail, the main objectives are the selection of the best performing combinations of technologies to be implemented in each case study. In particular so far, three shape scenarios of GET system have been examined for each pilot building of Pro-GET-onE taking into account the structure of the buildings, the climatic conditions as well as the social environment. The aim is to evaluate and to optimize each set of technical solutions or integrated solutions to comply to different building requirements while providing energy saving, safety/seismic risk, user oriented design by using a holistic approach;
An integrated BIM system will be applied to minimize construction time and optimize the energy, seismic, and the tailored solutions of selected technologies.
WP7 has just started, though some preliminary actions were organized like the Cost management and control. Regarding the Mock-Up, a single prototype built at the headquarters of the partner ALIVA. One Mock up with 2 different solutions is foreseen
For the following WP8, there has been already a detailed research on EU and National monitoring protocols, and in a further step the selection of the most appropriate protocol will take place.
In WP9 the communication strategy has been set up and updated twice and the project website was launched during M3.
Two specific ProGETonE events were organized (one national event in Italy and an international symposium in Groningen. Pro-GET-onE partners have joined a clustering initiative to share knowledge about deep renovation practices and challenges, together with P2ENDURE, 4RinEU and More-Connect. Three open access articles have been written. Currently tw

Final results

Pro-GET-onE is grounding on innovative process and services, combining existing technologies at TRL 7-8, thus using viable solutions in a disruptive, yet integrated and holistic manner. The resulting added value is in the achievement of a multi-benefit result, implementing and extenting previous findings in prefab and nZEBs renovation also for the case the structural renovation of buildings in seismic regions.
