This technical investigation canvases a range issues concerned with the development of a PIM Object Library, specifically to address carbon management, though the principles could be applied within a broader context. It deals with:

• levels of detail, identifying the broad classes of objects that must be handled at a precinct scale to support carbon management use cases;
• terminology, proposing how the ambiguity and complexity of varying domain nomenclature can be managed to yield some consistency;
• property data, reporting an investigation of available property sets to support carbon management in the built environment, and
• linkages to reference data relevant to implementing a precinct object library for low carbon urban policy, planning and design application.
