When and Why Should You Use JV3 Modelling?

When and Why Should You Use JV3 Modelling?
Over the past several years, the Australian
Building Code Board (ABCB) has been making
efforts to evolve the country's building policies
and the National Construction Code (NCC) 's
sustainable standards into a performance-based
compliance system. If you work in the building
and construction industry, you might have heard
the term' performance-based coding.' But what is
it? Performance-based coding solutions such as
JV3 Modelling were introduced to quantify more
innovative building designs while complying with
sustainability guidelines. The modern
performance-based coding solution uses a top-down
approach and provides overarching standards. And
you or your building experts can demonstrate how
the tailored approach fulfils and complies with
those standards. You can comply with the BCA
Section J using JV3 modelling and conducting the
JV3 compliance assessment. In this article, you
will learn about the JV3 modelling approach and
its benefits.
What is the JV3 Modelling Approach?

A JV3 Modelling approach is a performance
solution that helps buildings comply with Volume
1 of the National Construction Code (NCC). It
involves an entire building stimulation approach
for determining its performance compared to a
reference Deemed-to-Satisfy (DTS) building.
When and Why to Use JV3 Modelling?
JV3 Modelling simulations provide greater
flexibility in designing a building. Simply put,
with this approach, you can underperform the
energy efficiency features in specific areas and
balance the standard energy efficiency
requirements by overperforming in other
places. It can be advantageous, especially when
considering renovating or modifying the building.
When renovating and upgrading an existing
building, there might be several factors why you
couldn't change the features. In addition, it
might be impossible to eliminate certain features
in new constructions for various reasons. Such
conditions can include Cost-effective
solutions Even when two or more buildings have
the same design, each can vary in terms of energy
performance. Some features in one building might
be cost-effective, and the same features might
prove extremely costly in another. With JV3
assessment, you can improve energy performance
and introduce cost-effective sustainability
measures while reducing performance in design
areas where the construction cost can be
extremely high. Building consultants can also
help you identify cost-effective solutions for
the BASIX certificate required in residential
projects. Restoring heritage requirements You
might not find upgrading specific parts in the
heritage building practical or feasible because
of DtS constraints. JV3 modelling can help you
ignore those certain areas and boost energy
performance scores in unrestricted
areas. Eliminate design constraints

When looking forward to meeting the energy
efficiency standards specific to the government,
you will need more room to implement a
better-performing design feature. However, you
might not consider accommodating a design element
like thicker insulation in the building's roof
since you have strict RLs. JV3 Modelling can help
you compensate for energy performance
elsewhere. Allow better aesthetics If you
strive to construct a state-of-the-art
landmark-type project, you must consider your
project's vision and design aims. For instance,
you want to install stained glass windows, but
these windows or glazings usually perform
poorly. Moreover, it's impractical and costly to
install the double-glazed stained glass windows
without ruining the building's aesthetics. In
such a case, the JV3 modelling approach can help
you include this design feature without
compromising aesthetics and the overall energy
efficiency of your building. To sum up it
all JV3 modelling is an excellent approach to
fulfil the BCA Section J compliance. This
computer-based simulation can help measure the
overall energy-related performance of a
building. Moreover, with this approach, project
owners can use design elements that might not
otherwise comply with the conventional DtS
requirements and balance this energy loss by
compensating in another area in the building
design. When considering conducting a JV3
assessment or wanting a NABERS or BASIX
Certificate for your building project, consider
collaborating with an accredited assessor to
streamline the assessment process and paperwork.
