The scope of this deliverable is extensive, covering the theoretical underpinnings, practical methodologies, and technological aspects of a new, integrated operational rating system for buildings. It aims to provide a more nuanced, accurate, and comprehensive assessment of building performance, considering a wide array of factors beyond just energy consumption. This deliverable begins by outlining the context, background, and objectives of the project, providing a robust framework that sets the stage for the detailed discussions in the following sections. It clearly defines the scope and lays a solid foundation for understanding the operational rating system being developed.
Definition of Indicators: This crucial section delves into the indicators used to measure the operational rating, introducing and evaluating their precision and reliability in assessing building performance. The analysis includes a review of historical data to identify trends and considers the impact of variables such as weather conditions, occupancy patterns, and usage variability on these indicators. It also discusses the importance of certifications and standards in operational rating, highlighting the need for continuous improvement and relevance.
Selection of Indicators: This part focuses on selecting appropriate indicators for the operational rating. It discusses their relevance to building performance, data availability and reliability, and the methods used for evaluating and choosing indicators. Challenges and limitations of indicator selection are acknowledged, and the concept of thresholding is introduced. This section addresses Indoor Environment Quality Indicators, Operational Rating Indicators, and Financial Indicators, underscoring the multi-dimensional nature of building performance assessment.
Thresholding of Indicators: In this revision, there is a significant emphasis on the methodology for setting performance thresholds for the indicators. This process is crucial for ensuring that the indicators are robust and meaningful, distinguishing buildings that meet or exceed performance standards from those that do not, thereby enhancing the operational rating system’s effectiveness.
Future Work: This section looks ahead to the next major milestone, which will be the final and all-encompassing version of the SmartLivingEPC operational rating methodology. It will synthesize all prior work into a comprehensive and definitive methodology, reflecting the integration of all enhancements and feedback gathered through ongoing research and application.
Overall, this deliverable presents a detailed and progressive methodology for operational building rating, focusing on a comprehensive set of indicators beyond traditional metrics. It includes an in-depth analysis of indicator selection, with a new focus on thresholding, culminating in a synthesis of findings and implications for building performance assessment.
