I propose to take Questions Nos. 197, 198 and 199 together.
The introduction of the Nearly Zero Energy Building (NZEB) standard has seen a 70% reduction in the emissions of new buildings. Oil and liquid petroleum gas are no longer used as the primary heating source in new dwellings, with heat pumps now used in 84% of new dwellings, a percentage which will continue to increase as a result of the 2019 NZEB regulations, so that all fossil fuels will be effectively phased out in new dwellings by the end of 2023 and will be completely replaced by renewable energy heat pumps as the main heating system.
It is planned to implement a similar phase-out of fossil fuel boilers through performance-based regulations for new non-residential buildings and existing buildings undergoing major renovation (where more than 25% of the external surface of the building is renovated).
NZEB Regulations introduced in 2018 for new buildings other than dwellings have helped to accelerate the phase-out of fossil fuel boilers in these buildings by introducing renewable energy requirements for all new non-residential buildings and reducing their energy requirements and carbon emissions by 60%. It is intended that Building Regulations will be further updated to adopt the 2023 cost optimal calculations no later than Q1 2025, three years in advance of the statutory requirement of the Energy Performance of Buildings Directive.
Gas Networks Ireland have provided the following new connection data for 2019 to 2023 (up to end of February).

* Homes include both new houses and existing houses connecting to the gas network.
**A separate line-item figure for Communal Heating Scheme Apartments has been provided as these are typically recorded as NDM business meter fits.
