Information for Stakeholders

CHRONICLE will deliver a semantically enriched and BIM-based Common Data Environment (CDE) and relevant data governance services to ensure the efficient management of both static and dynamic building information. CHRONICLE’s CDE enables the management and collaboration of project information throughout the lifecycle of the project. The CDE will facilitate the sharing, management, and storage of data that is relevant to the various CHRONICLE stakeholders, such as AEC, building owners etc., and respective CHRONICLE tools. CDE will ensure that authorized users involved in the project have access to the most current and accurate information, and that the data is consistent, reliable and secure.

CHRONICLE’s Digital Twin framework acts as the spine of all the project’s activities, aiming to accurately model and simulate the building’s processes based on real life data, monitoring buildings operations and environmental conditions, collected through an IoT network installed on site. Combining powerful building thermal modelling techniques and machine learning algorithms, CHRONICLE’s DT Framework will accurately forecast the behaviour of the building’s conditions and systems. It will additionally mimic the behaviour of the building occupants to bridge the simulation gap and provide an accurate and representative building model, continuously calibrated based on current IoT data streams.

The Renovation Planner Tool is designed to help building professionals and homeowners plan renovations of buildings and dwellings. It will help to assess various renovation scenarios of the building, focused on optimizing its energy performance. Furthermore, the tool will present a complete financial assessment per renovation scenario proposed, while also evaluating other important factors like the tenants’ comfort and carbon emissions. Depending on the parameters that the user chooses to prioritize, the renovation planner will give a list with the best scenarios to proceed.

Each proposed scenario will contain and describe a renovation roadmap with concrete renovation measures to be applied. Continuing on from the selection of the preferred renovation scenario by the user, the Renovation Planner will also issue a building renovation passport (BRP) which will include and present all the details about future building inspections, maintenance and renovations in a pro-active manner based on the expected service life of the components, systems and materials to be used and applied during the renovations.

The Investment Appraiser is a tool that will be developed to forecast value and liabilities related to buildings’ performance as well as energy saving investments. Together with the other Chronicle applications, it will provide support to the stakeholders of the AEC Industry and its inhabitants.

The first part of the Investment Appraiser aims to support a property (building) valuation, performing a Life Cycle Cost (LCC). The application consists of a backend solution that performs LCC according to literature proven cost KPIs. This includes Dynamic Costs for instance, those associated with energy or water consumption and Static Costs as of those associated with Building Materials for renovation scenarios.

The second part of the Investment Appraiser oversees calculating the Carbon Bill for both the Base Line of each pilot and the generated renovation scenarios. According to the UC3.2 the Carbon Bill is an associated cost that measures the impact of emissions and sets an economic magnitude according to a standardized quantity.

The Performance Evaluator is an application that captures not only the actual and post-occupancy data, but also the simulated outcomes from the Digital Twin. End-users will be able to monitor building operations (e.g. energy consumption, heating loads, indoor air temperature) as well as receive recommendations in terms of energy, cost and comfort.

In general, the Performance Evaluator serves as the data analysis system supporting the functionalities of both ChroVieOcc and ChroViewPlus. It plays a crucial role in effectively assessing building usage and advise the users on how to improve the overall energy performance.

This online BIM-based tool enables (i) the three-dimensional (3D) visualization of the building and (ii) the monitoring of near-real time data from smart equipment installed on site, such as energy consumption, environmental conditions, and other performance indicators. These include energy usage analysis, costs, CO2 emissions, indoor air quality and tenant-user’s comfort. ChroViewFM’s dashboard allows the user to track the building’s energy use and comfort levels and, eventually, identify any significant changes over time. To this end, ChroViewFM provides notifications of upcoming maintenance activities and warnings of any unexpected behaviour of the building equipment, thus facilitating the building’s predictive and preventive maintenance. Finally, it offers a user-friendly 3D visualization tool, where the user e.g., Architect/BIM modeler, FMs etc., can upload actual or hypothetical BIMs of a building of interest.

The Digital Building Logbook (DBL) is an information repository for all relevant building data. It allows to store, organise, manage and trace information and data throughout the whole building’s lifecycle. It is a valuable resource for building owners and stakeholders (AECO, FM, OP ) to observe the evolution of the building based on trusted information and it facilitates decision making. The DBL bridges the gap between the great amount of data and information generated during the building’s life cycle and the lack of methodologies and tools to safely manage, organise, structure, and share this data.

The building information, milestones and data can be archived in one, secure place where it will be accessible to authorized parties in the long-term. The CHRONICLE Digital Building Logbook offers intuitive features (such as a timeline of the building’s lifetime) that supports the involved stakeholder’s decision making on critical decisions regarding the building management. It will offer multiple ways of searching for and managing data. Through the communication established with the Common Data Environment of CHRONICLE, results and information from other CHRONICLE solutions will be automatically stored in the logbook. The system uses blockchain technology to guarantee the integrity and traceability of your data. 

This mobile app will allow building residents understand and improve their energy consumption, transforming performance rating from an administrative document to a useful and comprehensive tool for the actual building tenants. Apart from insights on current energy performance, the app will provide indicators related to comfort and health conditions (e.g. air quality) per household as well as insights on the current ambient conditions, depending on the smart devices installed on site. It will also provide actionable suggestions on improving energy efficiency based on actual information collected per household, for example how to adjust the setpoints of the cooling or heating devices, how to consume energy when the production from renewables is maximum etc. This will result to tenants actually improving the energy efficiency of their home, further resulting to reductions in their energy bill.

The primary objective of ChroViewPlus is to assist Energy Service Companies (ESCOs) and Facility Managers (FM) in offering them expert recommendations and in-depth insights to effectively reduce energy consumption.

The user interface will be designed to analyse various operational strategies and their respective impacts on the overall energy performance of the building. The final application examines real-time system patterns, compares them with forecasted behaviours and provides recommendations for identifying opportunities to save on costs.

Overall, the interface will enable ESCOs and FM to achieve significant cost savings. By doing so, they will not only minimise maintenance expenditures, but also gain the capability to comprehensively assess and present the environmental impact of various operational strategies.
