Die detaillierte Kenntnis der Merkmale und Leistungen des Gebäudebestands wirkt sich potenziell positiv auf die Fähigkeit der Europäischen Kommission aus, im Hinblick auf die Strategie 2050 und den Europäischen Green Deal, wirksame Strategien für Gebäude zu entwickeln. Angesichts des Mangels an umfassenden und zuverlässigen Daten zum EU-Gebäudebestand wird BuiltHub einen strukturierten und umfassenden Datenerfassungsansatz sowie einen leicht zugänglichen und benutzerfreundlichen Datenhub in Form einer strukturierten webbasierten Plattform (IT-Infrastruktur, Analyse und benutzerfreundliches Dashboard) erstellen, welcher auf Vorteile und Einbeziehungsstrategie für Daten- und Metadatenanbieter basiert. Die erwähnte leistungsorientierte Einbeziehungsstrategie wird umgesetzt, indem Mehrwertinformationsdienste entwickelt werden, die auf die Hauptnutzer der Plattform und andere Hauptnutznießer (Endnutzer) zugeschnitten sind. Die Hauptvoraussetzung für den Vorschlag zum Aufbau einer BuiltHub-Gemeinschaft ist, dass Dateneigentümer bereit sind, Daten/Informationen in die BuiltHub-Plattform einzuspeisen, im Austausch für die Mehrwertinformationen/Kenntnisse, welche die Plattform durch ihren Betrieb bereitstellt. Darüber hinaus werden “Multiplikatoren“ die BuiltHub-Erfolge zur Erweiterung der entsprechenden Community verbreiten.
Das Konsortium wird auch verschiedene Datenprozesse und Serviceschemata entwickeln, um mögliche Benutzer abzudecken, basierend auf ihren Bedürfnissen und der potenziellen Verwendung von Daten und Analysen sowie den Vorteilen, die sie aus der Zusammenarbeit mit BuiltHub entstehen.
Das Projekt zielt darauf ab, auf der Datenbank des Gebäudebestandsobservatoriums und den zugehörigen Analysen aufzubauen, um den Datenfluss einfacher, robuster und sicherer zu machen. Das BuiltHub-Konsortium ist jedoch auch bereit für einen eigenständigen Entwicklungsansatz als Backup-Plan. Ziel ist es auch, eng mit verwandten Projekten und insbesondere dem Projekt B4E-6 MATRYCS zusammenzuarbeiten, indem der Datenerfassungsansatz und eine Standarddefinition der einzelnen Elemente auf verschiedene Ebenen (von Landes- zu einzelner Gebäudeebene) aufgeteilt werden.

The EU building stock progress toward decarbonization is very slow with an annual amount of deep renovations in the EU28 only around 0.2%. The detailed knowledge of building stock features and performances has a potential positive disruptive effect on the ability of the EC, MSs and ACs to design effective policies targeting buildings in view of the 2050 goals and the European Green Deal. Stated the lack of comprehensive and reliable data on the EU building stock, we will develop a structured and inclusive data collection, as well as easy to access & use datahub, in the shape of a structured web-based platform (IT infrastructure, analytics and user-friendly dashboard). The overall aim of the BuiltHub project is to define the roadmap and vision for a durable dataflow enabling to characterise the EU building stock. The above-mentioned platform will ensure such a long-lasting data flow through the engagement of the stakeholders by providing knowledge and related services. The datahub will be fed into thanks to such benefits based
engagement strategy targeted to data and metadata providers. Data are related to building performance and functionality, while metadata refers to building features and contexts. The former can be provided e.g. by facility manager and utilities, the latter e.g. by local authorities and citizens. The stakeholders’ framework that we are going to establish will enable automatic and semi-automatic connections to smart meters and existing databases, as well as “manual” collection of datasets coming from industry associations, research organizations, market players and policy makers.
Recommendations and practical approach can be directly usable for specific EU policy and possible specific
regulation/rules, promoting data collection at member state and local level, while involving the whole community of data collection practitioners.
We will develop the aforementioned tailored services for Lead-Users of the platform and the other main beneficiaries (End-Users and Multipliers). Lead-Users will directly use the BuiltHub results as available in the web-based platform, provide data and use knowledge, while End-Users will be engaged by the BuiltHub consortium to exploit the user-friendly platform in their activities, eventually providing data in return, to also continuously improve the platform usefulness and effectiveness. Users may also possibly pay fees for advanced services. Finally, Multipliers will disseminate the BuiltHub achievements, enlarging the related engaged community and boosting the building stock transformation. We have already identified an initial set of beneficiary stakeholders, while a more comprehensive mapping will be detailed within the project timeframe:
• Lead-Users: researchers, facility managers, real estate developers, utilities/aggregators
• End-Users: policy makers, designers, national and local authorities (e.g. urban planning departments), citizens
• Multipliers: stakeholders associations, media, EC/EASME

BuiltHub will deliver specific actions: (i) to reach each group and to create an engaged and motivated community by offering targeted services in return for their effort in providing data, as well as (ii) to give the deserved value to the provided services (coming from data post-processing and analytics). We will ensure a long-lasting data flow, working on private and public benefits in providing digital data to the BuiltHub platform. Such benefits will be available in the form of knowledge and related services accessible through the platform for e.g. benchmarking, supporting investment, and urban planning towards full decarbonization. A specific value proposition and related business case, and a robust marketing strategy will be developed for sustainability and durability of the engaged BuiltHub community and of the platform, with this becoming their reference data repository and tool box. The BuiltHub platform will offer differentiated service schemes
to face different possible users’ needs and potential use of data & analytics. The users’ benefits they can enjoy from cooperating with BuiltHub will be properly disseminated and communicated with tailored initiatives, and services access properly configured.
The BuiltHub project aims to build upon the Building Stock Observatory (BSO) database and related analytics, to simplify, strengthen and safeguard the data flow. BuiltHub will facilitate data collection for the current and next contractors, in particular referring to “how to collect data”, “which are the meaningful data (and metadata) to be collected”, “what should the data be used for”. While the direct connection with BSO is in principle the ideal case scenario, it includes two prerequisites: a) the BSO infrastructure is already solid and functionable and b) EASME supports this approach and enables timely access to the BSO backend, functionalities, data and metadata. Notwithstanding, if these conditions are not met, the BuiltHub consortium is also ready for a development approach which stands on its own, as a back-up plan, focusing on supporting the development of durable dataflow.
The BuiltHub consortium has a solid relevant background including H2020 Hotmaps (coordinated by TU Wien), H2020 ExcEED (coordinated by Eurac) and iBRoad projects (coordinated by SYMPRAXIS), the BuildUP service contract (currently managed by EVERIS), 1st BSO EC service contract coordinate by BPIE, representing a very good starting point for developing the BuiltHub concept and implementing related activities.
