CHRONICLE

Assessment Methodology for Building Energy Ratings

Project Summary

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' Role

IES integrates the whole Digital Twin (DT) framework which consists of a physics-based platform working together with data driven models (occupant behaviour data). IES is responsible for ensuring the physics-based Digital Twin is BIM-based and for maintaining seamless interoperability between platforms.

Additionally, IES is the lead partner for one of the project's final end-user applications, which provides an operational decision support service for commercial buildings. Particularly, IES will create a UI to assist ESCOs and other professional stakeholders with operational data analytics and optimal control strategies. It will offer them expert recommendations and in-depth insights to effectively reduce energy consumption

Upon the project’s completion, ESCOs and Building Owners will be able to achieve significant cost savings not only to minimise maintenance expenditures, but also gain the capability to assess and present the environmental impact of various operational strategies.
