The TGD are changing to incorporate the NZEB requirements. Irelands building regulations have changed significantly since 2005 in an effort to meet the European 2020 targets. The Technical Guidance Documents (TGD) part L has improved from 2005 to 2011 by 60% in relation of energy usage. The table below highlights the changes from 2005 to 2016 with their differences and the improvement on efficiency of residential buildings.
TGD changes Ireland

The DECLG have proposed a 70% improvement in energy usage compared to the 2005 TGD reference dwelling. The DECLG stated that the new building regulations are to be published in 2016 and will be implemented on a voluntary basis. There has been no exact specification published for the NZEB standards in Ireland yet but they have specified the Energy Performance Coefficient (EPC) of 0.302 and Carbon Performance Coefficient (CPC) of 0.305, the maximum primary energy for a NZEB residential dwelling will equate to 45 KWh/m2y, which will be a BER of A2

The TGD Part L ‘Conservation of Fuel and Energy – Dwellings’ details a building’s energy requirements to comply with the Irish Building Regulations 2011. The TGD specify that new dwellings must have a renewable contribution of no less than 10 kWh/m2/annum for domestic heating, hot water supply or cooling or 4 kWh/m2/annum of an electrical energy supply or a combination of both.
