Charlestown is a mixed-use development in Dublin 11 comprising of 285 apartments with an 18,800 sq meter shopping centre with Dunnes Stores as the anchor tenant. Charlestown uses its own district heating system (DHS), which sources heat in the most environmentally aware manner possible. Central to this effort is the Energy Centre which generates heat and power for all of the customers on site using a high efficiency combined heat and power (CHP), a biomass boiler with locally sourced wood pellets and backup gas fired boilers. The pellets used are zero-rated for Kyoto Protocol carbon emissions, given it is recycled carbon from Irish timber.
