Certification of Near Zero Energy Buildings Ireland nZEB

What is the nZEB standard?

The European Energy Performance of Buildings Directive  Recast 2010 (EPBD) requires all new buildings to be nearly Zero Energy Buildings (nZEB) by 31st December 2020 and all buildings acquired by public bodies by 31st December 2018.

Residential buildings: The Irish Government is implementing the Energy Performance Building Directive 2010 recast through revised building regulations for homes which are proposed to come into force on 1st April 2019. This means that any dwelling receiving planning permission after 1st April should meet the nZEB standard. Substantial completion must have been achieved by 1st April 2020. After 2020 all homes irrespective of when they received planning permission should achieve the new standard.

NZEB
 
Non-residential buildings: The revised regulations require buildings to use up to  60% less energy than allowed under current regulations, plus a requirement for up to 20% of this final demand to be met with renewables.  If a higher level of efficiency is achieved the renewables ratio may be reduced to 10% of final demand. Note: final demand does not include tenant equipment. This comes into force on the 1st January 2019, with a transitional arrangement that does not extend beyond the 1st January 2020. This means that the current regulations – Technical Guidance Document L -conservation of Fuel and Energy (2008 ) can only be used beyond 1st January 2019 if Substantial work had been completed by 1st January 2020 one year ahead of the 31st December 2021 deadline for NZEB itself.
