Section J Compliance – The options that save you money.

The routes of Section J Compliance

Deemed-to-Satisfy

The most common route to Section J Compliance is though Deemed-to Satisfy (DtS) in the form of a Section J Report. This report is the cheapest and usually easiest of the options to complete, but may lead to a building that costs more to construct and operate.

Performance Solution

The other main route to Section J compliance is a performance based solution, most commonly JV3’s. This allows for maximum design flexibility and the benefit of determining how some differing design options will not only affect constructions costs, but also running costs.

Combination Approach

The final approach to Section J Compliance is the combination approach, this approach, as it would sound, it a combination of Deemed-to-Satisfy and JV3’s.

Deemed-to-Satisfy, Section J Compliance Report

If you are designing a commercial building and you hear the words; energy efficiency report, then its most likely a DtS Section J Compliance Report that is being discussed. This is the most common and easiest means of determining compliance. The DtS provisions of the code are a important part of compliance, not only for energy efficiency, but many aspects of compliance such as fire and health.

DtS provisions are very prescriptive and don’t allow for much innovation or creative design by nature. If you’re building a very simple type of building that uses traditional building materials and construction methods, then this is likely your best option. It’s quick, easy and cheap.

However it doesn’t take a NASA sized step outside of the box before this method becomes too difficult to use. Straightforward requirements like clear glazing for showroom displays can quickly turn a simple job into one that’s more complex that DtS allows for.

Pros:

  • Reports completed quickly
  • Cheapest of the options

Cons:

  • Little flexibility
  • Not able to fine tune construction and operational costs

Performance Based Building Code, Section J Compliance – JV3

For years, the Australian Building Code board (ABCB) has been trying to move the requirements of the National Construction Code (NCC) towards a performance based code. Those who’ve worked in around the building industry for any amount of time have probably heard this turn of phrase, but what exactly does it mean?

The intent of a performance solutions is to give the ability to quantify a more innovative design approached. The Deemed-to-Satisfy provisions of the building code are more prescriptive. They are a ground up approach to meeting the requirements of the code, complete each part and you will have a compliant design.

Performance Solutions are more of a top down approach. The building code gives you some over arching requirements and it’s up to a specialist to demonstrate how their customised approach meets those requirements.

Section J Compliance can be confirmed by completing a performance solution known as a JV3. This is a computer based simulation that allows you to measure overall building performance and enables you to use components that may not otherwise meet DtS requirements and offset these losses by compensating elsewhere. For instance you could install cheaper lower performance windows and offset this with higher performing wall insulation.

Pros:

  • Can reduce construction costs,
  • Can reduce operation costs,
  • More flexible consruction options,
  • More holistic approach.

Cons:

  • More time to prepare report,
  • Reports may cost more than DtS.
