While several studies have analysed the end use energy demand at the urban scale, the definition of ‘energy intensity’ used frequently in this field is not completely clear. To clarify this ambiguity, this paper defines ‘Urban Energy Density’ (UED) to unify the current definitions and to create a link between energy management and urban planning. UED is the total amount of end use energy (kWh) demanded, predicted or consumed in a building normalized by the total building area or its footprint area during a year. The research has developed an ArcGIS Energy Dataset (AED) to create an UED map of the International Financial Services Centre zone, (IFSC), Dublin, Ireland using CIBSE energy benchmark data. In this UED map the major end use energy consumers in 29 building categories and their dispersion in the region are analysed. The map shows that the IFSC zone needs approximately 152MWh energy per year and the Convention Centre Dublin has the highest UEDg of 570kWh/m2 while, the lowest UEDg is associated with a covered parking lot in the south of the site with an energy demand of 20kWh/m2 per year.
