Nearly Zero-Energy Buildings (NZEB) Requirements for New Buildings

Regulation 43B of the Building Regulations Northern Ireland 2012 as amended requires that a new building must be a nearly zero-energy building.

Nearly Zero Energy Buildings are defined as highly efficient buildings requiring very low energy consumption and where energy is required, the majority of their energy requirements should be derived from renewable sources either on site or nearby.
