TIMEPAC anticipates that new indicators (for example sustainability indicators, Smart Readiness Indicator, etc.), combined with real consumption data, will allow a more accurate reflection of a building's energy efficiency as they consider the actual usage patterns. This approach contrasts with static or outdated data, which may rely on assumptions or historical usage patterns. Current practices, where building-related data are used only for single or dedicated purposes, are unsustainable and cannot effectively assess the actual performance of buildings throughout the lifetime. It is crucial to facilitate interoperability between existing databases, previously developed digital models (such as BIM or BEM), and past energy-audit reports. 

This session will provide practical and effective tips for efficient EPC data collection, validation and exploitation. Initially, attention will be directed towards clarifying the goal and purposes of data collection, followed by an exploration of the relevant data needed for generating reliable EPCs. Using several EPCs from Croatia as examples, conclusions will be drawn from the adopted data processing. These insights will be conveyed to participants through analysis and examples of best practices.

An improved EPC relies on an understanding of the data collection processes in building energy performance certification, including the tools used to gather and verify the accuracy of data. We will address the challenges associated with extracting data from multiple sources, such as incomplete datasets, data inconsistency, and missing data points. Best practices for managing these issues will be explained, providing participants with the knowledge necessary to ensure that the data used for an EPC are accurate and meets the required standards. 

Performing quality assessment of the EPC database contents is essential to ensure energy certificates are accurate and reliable for informing policy decisions, benchmarking building performance, and implementing energy efficiency upgrades. This session aims to offer an overview of a method for quality-checking procedures developed within TIMEPAC, which includes validating values in energy certificates according to predefined rules and thresholds.

An energy performance assessment of a building, if conducted systematically and comprehensively, serves as a powerful tool for evaluating current or past energy and environmental performance, as well as management practices. Preparing for building site visits is crucial for any activity related to the energy performance assessment. The planning activities should be documented in the form of a work plan, which should also be shared with the owner/users before visiting the building to carry out the intended work. This session will present main elements of proper planning and conducting site visits. 

This session will demonstrate how Building Information Modeling (BIM) can enhance Energy Performance Certificates (EPCs). It will highlight how BIM tools enable the analysis and visualization of EPC data, supporting the creation of innovative energy services and facilitating deep energy renovation projects. Additionally, it will explain the benefits of using BIM models for EPC generation, such as reducing errors and increasing efficiency and productivity.

Effective strategies for sustainable and climate-friendly urban development must be adaptive and grounded in empirical data. In this context, integrating the Smart Readiness Indicator into a building’s energy performance assessment holds significant potential to facilitate sustainable change in current development practices and to transform existing building stock into major energy-generating entities. This session will offer an overview of the SRI assessment methodology and outline the key elements of the TIMEPAC Code of Conduct for Smart Readiness and Sustainability Rating.

Buildings do not exist in isolation but are integral components of a broader urban system that encompasses environment, transportation, infrastructure, governance, among other elements. The primary purpose of any indicator is to simplify complex systems, making them understandable and easily comprehensible. Assessing sustainability is a multifaceted endeavor, requiring interconnected sets of indicators to evaluate how well a given system, such as a building stock, aligns with established sustainability objectives. This session provides an overview of sustainability indicators from the Level(s) framework, with a particular emphasis on those relevant to improving energy certification. These indicators encompass various aspects such as use stage energy performance, indoor air quality, and life cycle costs.
