Spatial mapping of heating and cooling (i.e. thermal) demand in Ireland (ex. Northern Ireland).
These datasets result from the SEAI's National Heat Study. Specifically, Section 8 of Report 1: "Heating and cooling in Ireland today" (link). Both heating and cooling demands are split into four sectors: residential, industry, commercial and public services at the spatial scale of small area which is defined by the Central Statistics Office (CSO).
Zipped collections of shapefiles are available in two spatial reference or coordinate systems: 
1) Irish Transverse Mercator (ITM, EPSG:2157) 
2) WGS 84 Web Mercator (EPSG:3857)
