Section J of the National Construction Code (NCC) requires minimum levels of energy efficiency to be achieved for non-residential buildings (Class 2-9) to reduce the amount of energy a building requires for its normal operation.
The main elements which are assessed include:
facade (glazing and walls)
Section J method of assessment is essentially a ‘checklist’ solution whereby each building element must meet the Deemed-to-Satisfy provisions set out in Volume One of the National Construction Code (NCC).
There is no flexibility with this method of assessment as each element needs to comply independently.
The advantage of this method is that it is fairly quick and works well for simple buildings with minimal glazing.
JV3 Alternative Solution is an alternative method of compliance.
JV3 involves a 3D computer simulation to demonstrate that the annual energy consumption of the proposed building is equivalent or better than the annual energy consumption of a reference building which complies with the Part J DTS provisions.
There are many benefits to JV3 assessments. This is mainly derived from the ability to consider the building as a whole, instead of individual components in isolation.
This provides much greater design flexibility and the ability to “trade off” between different building elements, often resulting in more cost effective building specifications such as increasing insulation rather than upgrading to double glazing.
