Non Domestic Compliance using NEAP

Building Control now insist on a NEAP report before work starts, to ensure that the design is compliant to the 2008 Part L Building Regulations for buildings other than dwellings. A Final  NBER certificate with NEAP report and Airtightness Test is needed by Building Control when the building is complete. Building Control will not allow the client to rent, sell or take ownership of the building until they issue a certificate of compliance on completion.


A BER Assessor must publish the Final NBER certificate in an independent manner in accordance to the SEAI Code of Practice.

The calculation will take account of construction type, levels of insulation, ventilation, airtightness, fuel types, heating and cooling systems, controls, lighting, distribution losses, renewable energy contribution etc.


The Building Regulations will be revised at the end of 2015 and will be 40% more energy efficient than the 2008 levels. These Part L building regulations will be further revised by January 2019, for all new public buildings. From this date all public buildings will be constructed as Nearly Zero Energy Buildings (NZEBs) which will have a higher energy efficiency level.

—‘Nearly Zero-Energy Building’ means a building that has a very high energy performance. The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby
By January 2021, all non domestic buildings will be constructed as NZEBs.
