The Non-Domestic Energy Assessment Procedure (NEAP) is Ireland's official methodology for calculating a Building Energy Rating (BER) for non-domestic buildings.
NEAP software calculates BERs and demonstrates compliance with Part L using the default calculation tool, the Simplified Building Energy Model (SBEM), or by other approved software packages. NEAP considers space heating and cooling, water heating, ventilation, and lighting, to calculate the energy consumption and carbon dioxide emissions in a building. NEAP software packages must be approved by the SEAI and can be classified as Dynamic Simulation Modelling (DSM) or Interface for SBEMie.
SBEM has been developed by BRE on behalf of the UK’s Ministry of Housing, Communities, and Local Government (MHCLG) UK MHCLG has enabled the adaptation of SBEM for official use in Ireland within the framework of NEAP.
