NCC Volume 1 Section J


This course will assist industry in getting up-to-date with the significant changes to Section J in the NCC 2019, with an emphasis on its impact to the energy efficiency provision.

Recent changes to Section J will be identified and explained, with a focus on Part J5 and JV3 (Verification Using a Reference Building). Practical examples will be worked through, including a step-by-step approach to both DTS and JV3, plus the processes involved in producing the modelling to achieve the required outcomes. Solutions to compliance difficulties within J5 will also be discussed.

Other sections of the NCC have undergone significant updates. All engineers within the construction industry should review these. It is important to gain a holistic understanding of the entire NCC, such that assessment of the energy efficiency of buildings does not adversely affect the performance of other aspects of a building.

Intent of the new Section J

Building envelope and the glazing calculator

Performance provisions

JV3 – why Verification Using a Reference Building is in the NCC and how the results are checked and regulated

Performance methods
