Periodic Reporting for period 1 - CHRONICLE (Building Performance Digitalisation and Dynamic Logbooks for Future Value-Driven Services)
Berichtszeitraum: 2022-07-01 bis 2023-12-31
Buildings, constitute 40% of Europe’s energy consumption. The stock is inefficient, old, and 80% will still be in use by 2050.
Increases and Improvements in design and renovation practices are required for decarbonisation.
Calculating emissions from buildings is difficult due to their variability, assumptions used, and data quality. Emissions from the operational phase and the full lifecycle (materials, construction, maintenance, renovation, destruction, disposal) must be considered using energy and carbon metrics.
Real time data and knowledge of component performance in lifecycle assessment (LCA) could lead to more precise, robust, and cost-effective assessment of building performance, operations and maintenance; allowing comparison of new builds and renovations.
More reliable and informative building performance results addressing building and human-centric aspects from live building data is paramount to wider acceptance, deployment of future building assessment practices, and the success of EU Climate strategy.
The Energy Performance of Buildings Directive (EPBD) recast, introduces the Smart Readiness Indicator (SRI) to assess the level of smart readiness of buildings to adapt to occupant and grid needs. The New European Bauhaus wishes to ensure investments in energy performance consider core architectural ideals such as the social and aesthetic aspect by promoting co-creation in design/use over the building life; these aspects are not currently addressed or easily comparable.
Initiatives like Energy Performance Certificates (EPCs), incentivise phase out of inefficient buildings. EPCs are mandatory in EU Member States for construction, sale, or rental of a building. Despite positive contributions there are areas for improvement, there is no unified methodology for operational performance, limiting their use for decision making beyond the point of sale or change of occupant.
Life Cycle Assessment (LCA) product data on materials, processes, energy, and transport using Environmental Product Declarations (EPDs) is increasingly available. A standard framework for organizing and accessing LCA data, such as a Digital Building Logbook (DBL) leveraging Building Information Modelling (BIM), could improve LCA data accessibility and usability. A framework should establish secure, transparent, comparable and flexible information exchange; increase awareness, facilitate collaboration, and ensure high interoperability to achieve a holistic and dynamic building lifecycle assessment, using live information to incorporate building and human-centric aspects.
CHRONICLE will deliver a holistic, life-cycle performance assessment framework and tool-suite for buildings, supporting sustainable design, construction; and efficient renovations and investments.
It will integrate initiatives, like EPCs, Level(s), SRI, under the Digital Building Logbook concept. Performance will be assessed by well-defined KPIs, based on static (design) and dynamic (measurement) information for different types of use and building phases (new or under refurbishment). Continuous monitoring and analysis of real building lifetime performance will be based on digital twins (DTs).
The data availability and accessibility will extend EU energy related policies while advanced building performance information will facilitate efficient energy planning, allowing stakeholders to quantify the short and long term impact of activities, from policy to practice, across the whole life cycle for better planning of upgrades and renovations and de-risking of investments through an accurate LCA.
CHRONICLE will promote evidence-based impact assessment to support coherent policy, design of smart penalties and reward schemes to motivate energy consciousness, while paying attention to the market stakeholders (AECs Architecture, Engineering and Construction; ESCOs, Energy Service Companies; and FMs, Facility Managers)) and building owners and tenants/occupants.

CHRONICLE will realise a complex integrated system, in the first 18 months the following progress was made.
The definition of the system architecture in accordance with the system component definitions was delivered and a list of technical requirements was iteratively defined.
Business scenarios and use cases related to the technical components were described.
To ensure alignment of the use cases with real world needs feedback was sought through surveying professional stakeholders and building residents. Over 80 Key Performance Indicators (KPIs) were investigated. KPis were evaluated for implementation feasibility and the implementation barriers and relevance were reviewed. Short-listed indicators were tested with early data, to finetune and consolidate calculation methods.
Existing data models were investigated to address the fusion of Building Information Modelling (BIM), Internet of Things (IoT), and KPI requirements of the architecture.
The Common Data Environment (CDE) was developed to ease integration of the system components.
The functionalities specifications and services of the Data-Driven Digital Twin (DT) and the architecture and data model of the Physics-Based DT were designed and their development is ongoing in alignment with other components under the defined system requirements.
The integration of the DT models has been discussed to identify co-simulation scenarios for the integrated DT framework prior to actual integration.
The methodologies and use cases were integrated into the definition of the applications to be developed, listed below.
A BIM-based dynamic building logbook employing distributed ledger technologies (ChroView DBL interface.).
User-friendly GUIs for stakeholders, with enhanced UX for building performance monitoring, assessment, and certification were designed. The UIs, ChroViewOcc, ChroViewPlus, and ChroViewFM, cover services from real-time monitoring to benchmarking and personalised recommendations.
Applications for enhanced building renovation design , including the Building Renovation Passport and WLC framework with multivariate optimization services balancing cost, values, and risk were designed. (Renovation Planner and the Investment Appraiser)
Site surveys in the 5 pilot sites were conducted to identify available infrastructure, informing the design of bespoke IoT systems currently being installed.
A set of validation tools was developed and tested in the demonstrator test beds prior to use in the pilots. The processes are designed to provide a holistic building performance framework.
The outcomes described represent significant progress towards the project’s goals which will lead to realisation of defined impacts later in the project.
