Assessment Methodology for Building Energy Ratings
Building performance assessments generally rely on as-built features and are only delivered at commissioning stage. They do not consider the entire lifespan of a building nor the environmental impact throughout all phases of its life cycle. However, the service life of buildings’ components, as well as the maintenance work have a long-term impact on the operational cost.
CHRONICLE project aims to deliver performance assessment that supports sustainable buildings and investment decision making over the life cycle. It includes human centric, social, economic, sustainability and whole life carbon indicators to a BIM-based framework that allows all stakeholders interaction.
The methodology will be based on both static and dynamic data, as continuous monitoring of the actual building performance over its lifetime will be part of the assessment. Onsite measurements through IoT solutions, weather stations and open BIM data will be connected to the Digital Twin updating the models automatically. Finally, a set of applications for energy and life-cycle assessment will help end-users to predict, track and validate different building renovation measures through flexible what-if-scenarios and cost-benefit analysis.
IES integrates the whole Digital Twin (DT) framework which consists of a physics-based platform working together with data driven models (occupant behaviour data). The DT continuously receives live data streams from the cloud-based data environment that gradually improves its accuracy.
Additionally, IES is the lead partner for the project’s final end user applications. The DT provides the open interfaces for 3rd party applications. In particular, IES will create dashboards to assist both Facility Managers and ESCOs with operational data analytics and optimal control strategies. Also, it will design mobile apps showing to the end users the impact of their behaviour and how to achieve a future-proof energy efficient building.
Upon the project’s completion, ESCOs, Facility Managers and Building Owners will be able to optimise their investments, renovation and operational strategies and receive automated alerts on suspected or forecasted building performance degradation
