OPTEEMAL D2.1 Requirements and specification for the District Data Model

The objective of OptEEmAL is to develop an Optimised Energy Efficient Design Platform for refurbishment at district level. The platform will deliver an optimised, integrated and systematic design based on an Integrated Project Delivery (IPD) approach for building and district retrofitting projects. This will be achieved through development of holistic and effective services platform that involves stakeholders at various stages of the design while assuring interoperability through an integrated ontology-based District Data Model. This deliverable is the outcome of Task 2.1 “District Data Model requirements definition and specification”. The aim of this task is to define the requirements that the District Data Model (DDM) needs to meet to facilitate the OptEEmAL platform functionalities. The DDM integrates all of the data required to perform a refurbishment analysis of buildings within a district, including: Building data, District data, Contextual data, DPIs, Intermediate results, targets, barriers and boundaries. Building data will be collected and stored using BIM-based tools; district data will be managed with GIS systems; contextual data will be collected from the municipality or from open data repositories (climate agencies, national statistics agencies…); targets, barriers and boundaries will be set by the users; and intermediate results and DPIs will be generated by the platform tools or using external tools. The DDM plays a key role to ensure the interoperability between different standard data models. The proposed DDM is a comprehensive semantic framework which facilitates the intertwining of standard data models with domain specific ontologies. The DDM will be implemented as a set of interoperable data repositories. At this stage of the project five repositories have been envisaged: BIM repository, City repository, Contextual repository, ECM catalogue, and Platform database.
