What is nZEB?

From January, 1st 2019 every new public building will have to be designed to nearly zero energy building standards. Also, all other new buildings will have to comply with the new nearly zero energy buildings standards from January, 1st 2021. This arises from the Recast European Performance of Buildings Directive 2010/30/EU.

For dwellings, the NZEB standard will equate to an A2 BER with a primary energy value of 45 kWh/m2/annum. This takes account of the energy load for space heating, water heating, fixed lighting and ventilation. A very significant proportion of which will be covered from renewable energy sources produced on-site or nearby. (Ref: Towards Nearly Zero Energy Buildings in Ireland Planning for 2020 and beyond.

As measured by the DEAP BER method, the NZEB standard will require an Energy Performance Coefficient (EPC) and Carbon Performance Coefficient (CPC) not greater than 0.302 and 0.305 in accordance with the common general framework set out in Annex I of Directive 2010/31/EU on the energy performance of buildings (Recast).

All Glavloc® buildings have fabric energy ratings well below the requirements as specified in updated Irish building regulations.
