This report covers the development of the D^2EPC core Calculation Engine, which includes the Asset Rating Module, the Operational Rating Module and the Building Performance Module (BPM). The document provides a detailed description of the main activities that took place to implement the sub-modules, along with their functionalities. The report also outlines the actual implementation of the components up to M24 of the project, considering the current development status under a public dissemination level.
Firstly, the document aims to provide the user with an overview of the proposed holistic energy performance certification scheme. To this end, the theoretical foundations of the applied methodologies are provided to describe the included functionalities. The Asset and Operational Rating schemes for the building’s energy performance provide a clear distinction when examining an asset using static and dynamic data. Moreover, the provided set of indicators expands the provided functionalities and the end-user’s awareness about the performance in the domains of automation/control (SRI), sustainability (LCA, LCC) and human comfort and wellbeing.
The development of the aforementioned components is detailed in the second section of this report. The applied algorithms are provided in each case as charts and diagrams. Additionally, each calculation has a description of the required data sources. Integrating the developed component into the D^2EPC platform, especially with the Building Digital Twin module, will enable the automation of certain calculation procedures. Finally, each component is tested based on data from one pilot building. The resultant indicators from each calculation are provided in the last part of this report.
