This Deliverable outlines the Use Cases of the SMARTLAB project. These Use Cases are based on buildings which have been selected by project partners to give an accurate representation of the building stock in the project area in Limerick city. They draw on an analysis of available sources of statistical data on Irish buildings and insights from the project partners’ areas of expertise. This Deliverable sets out the process used to identify Use Cases within the project and outlines a schematic of those Use Cases chosen by SMARTLAB partners. Fundamental to the discussion of Use Cases in the project was a decision on the project focus area, as any Use Case would have to fit an area profile once this decision was made. Accordingly, this Deliverable also delineates the process by which the project boundary was agreed.
