Background
Under the Council of Australian Governments (COAG) 2015 National Energy Productivity
Plan (NEPP), and with endorsement by the Building Ministers Forum, the Australian
Building Codes Board (ABCB) was requested to update the energy efficiency provisions in
NCC 2019.
The NEPP is a COAG Energy Council agreed package of measures, which aims to
improve Australias energy productivity by 40 per cent by 2030. Measure 31 of the NEPP
forecasts strong productivity and emissions reduction benefits from revising the NCCs
energy efficiency provisions, particularly for commercial buildings.
On this basis, for NCC 2019 the ABCB was instructed to focus on increasing the
stringency of the energy efficiency provisions for commercial buildings (the subject of this
document).
Introduction
This case study is one of a series produced by the ABCB to support the Public Comment
Draft of 2019 NCC. The purpose of this Case Study is to help illustrate the impact of the
proposed changes to Section J of Volume One of the NCC. It shows what changes, if
any, a building designed to meet the 2016 NCC provisions of Section J would need to
make in order to comply with those of the NCC 2019.

Note that any opinions on the impact of the proposed changes to Section J are expressed
by the Case Study author. It should not be regarded as those of the ABCB nor an
indication that the NCC will be changed to reflect these opinions.
It should be further noted that part of the proposed changes to Section J in NCC 2019
include changes in the calculation methodologies used to determine predicted energy use
by components in a building. This can make direct comparison between the 2016 and
2019 versions of a building solution difficult. Instances where this issue arises are
highlighted in the text.

EXECUTIVE SUMMARY
WSP has been approached by the ABCB to test the draft revisions of the NCC 2019 Section J revision as it impacts upon
NCC 2016 compliant buildings. This report outlines the impacts on the Collins Arch Development a mixed use high
rise building which contains Class 2, 3, Class 5 and Class 7, incorporating residential, retail, hotel and office zones in
Melbourne, VIC.
The building was designed with Green Star in mind targeting a 5 star Green Star Design & As-Built v1.1 rating, and 5
star NABERS rating for the commercial office. Due to these targets, the building is efficient by nature incorporating
high efficiency air-conditioning systems with extensive shading and a high-performance faade. The building achieves
NCC 2016 compliance through the verification method JV3 for building fabric (Parts J1 and J2) and DTS compliance for services resulting in a hybrid compliance solution.
In order to comply with the Draft Section J Requirements for NCC 2019 through Verification Method JV3 no items on the building fabric were altered from those of the existing building (Parts J1 and J2). This results in a null cost impact.
In order to achieve compliance with the proposed DTS requirements Section J of the NCC 2019, some minor changes
need to be made to the HVAC and Ventilation systems. This includes doubling the thickness of refrigeration and heating
hot water pipes. Although theoretically these changes can be made, it would require significant coordination work with
the architect and other disciplines and there is no guarantee that the spatial requirements would be able to be
accommodated.
The lighting design for the Collins Arch project was found to be compliant with the proposed requirements of 2019 with
the exception of the lighting power density in the hotel and commercial lobbies and hotel standard rooms. Compliance
could be achieved in this instance through reducing the lighting installed and no cost addition would be expected,
however the amenity of the spaces may be impacted. Alternatively, the project could seek to demonstrate compliance via a
JV3 Verification Method for the building services, allowing the higher lighting power density in the hotel and commercial lobbies and the hotel standard rooms to be offset by higher performing spaces elsewhere in the building.
The lifts proposed for the building are expected to be compliant with the 2019 requirements.
The building and services were found to be generally in accordance with the new provisions of Section J of the NCC
2019. Minimal cost impact is expected to make minor changes to the systems design to meet the more prescriptive
provisions of Parts J5 and J6.

2.7 OTHER MEASURES INFLUENCING NCC COMPLIANCE
In order to achieve compliance with the proposed requirements Section J of the NCC 2019, some changes need to be
made to the HVAC and Ventilation systems. Many of these changes are related to sizing of plant and equipment.
Although theoretically these changes can be made, it would require significant coordination work with the architect and
other disciplines and there is no guarantee that the spatial requirements would be able to be accommodated.

3 SIMULATION PARAMETERSIn order to confirm compliance with the draft provisions for NCC 2019 Section J a JV3 an energy simulation wasperformed to compare the proposed compliant design against a reference design determined using the DTS provisions
identified in NCC 2019. These simulations were based on the following parameters
3.1 WEATHER FILE
To accurately model the dynamic nature of buildings thermal response, hourly-recorded weather data is used in the
thermal simulation. Such weather data contains records of radiation, temperature, humidity, sunshine duration and
additionally wind speed and direction.
A Test Reference Year for Melbourne has been used for this study; chosen using an ASHRAE approved procedure. ATest Reference Year is hourly weather data for a year for use in simulation of the performance of active and passive solar
energy systems, building energy consumption and indoor climate calculations.
The Validation Protocol states that ACADS-BSG/CSIRO weather data is acceptable. Both ASHRAE and CSIRO procedures use the same weather information and calculations to produce a test reference year. Therefore, the ASHRAE
test reference years is equivalent to the ACADS-BSG/CSIRO test reference year and meets the requirements.
3.2 BUILDING LOADS
Building loads determine the heating and cooling requirements of a building. They come from sources such as occupants,
equipment, lighting and solar loads. The internal loads; occupant, lighting and equipment loads, are detailed below in
Table 3.1, Table 3.2 and
Table 3.3 with values and profiles taken from design team specifications and NCC 2019.

4 SIMULATION RESULTS FOR
PERFORMANCE BASED CASEA building simulation was prepared for both NCC 2016 compliance through verification method JV3 and for a 5 Star
Green Star Design & As Built rating.
The simulation was performed for both JV3 compliance and the Green Star assessment using EDSL TAS 9.3.3; an EN
ISO 13791 validated dynamic simulation modelling (DSM) software tool using a TRY (Test Reference Year) weather
file of Melbourne . The Green Star assessment also involved further additional calculations of energy use estimated through hand calculations.
A comparison of this simulation against the JV3 assessment results for NCC 2019 are shown below in Table 4.1
indicating the greenhouse gas reduction for the proposed fabric against the reference model with DTS services.

5 ECONOMIC ANALYSISA high level economic analysis of the design changes required to meet compliance with the proposed provisions of
Section of the NCC 2019.
5.1 BUILDING FABRIC AND GLAZING
The assessment of the provisions in relation to the building has found that the building fabric and glazing as per the
current design is deemed compliant via Verification method JV3. Therefore no changes to the building fabric or glazing
is required.
5.2 MECHANICAL SERVICES
The assessment of the mechanical systems design has found that changes would need to be made to the following
elements. A high level estimate of the cost impact is provided.

COMPLIANT COST
INDICATIVE 2019
COMPLIANT COST
Dampers Motorised dampers would be
needed to be added at every
riser take-off at every floor.
The tempered outside air to
the hotel does not include
motorised dampers. As this
balances the toilet exhaust,
we believe that dampers
would not be required.

Pipework Some pipework will need to
be upsized to reduce
pressure drops of straight
length piping
Nominal cost difference. Coordination issue
Pipe insulation High temperature refrigerant
piping and heating hot water
piping will need to be
nominally doubled in
thickness.
Piping insulation is expected to increase from
approximately $8/m to $30/m
Total cost difference Dependent on length of piping

The cost difference of the design changes nominated above is expected to be nominal as it is related to the piping
insulation only.
5.3 ELECTRICAL SERVICES
A number of tested areas did not satisfy the proposed 2019 lighting power density requirements. If these non-
compliances could not be carried by the remainder of compliant spaces over the entire development, then the lighting
density would need to be reduced. On this project, the net cost result is likely to be a minor saving. There would be
anticipated to be greater consultancy costs associated with developing solutions that meet compliances, however if the
solution requires fewer lights, then the installation costs will likely reduce.

6 CONCLUSIONSIn order to comply with the Draft Section J Requirements for NCC 2019 through verification method JV3 no items were
altered from those of the existing building. This results in a null cost impact.
In order to achieve compliance with the proposed requirements Section J of the NCC 2019, some minor changes need to
be made to the HVAC and Ventilation systems. This includes doubling the thickness of refrigeration and heating hot
water pipes. Although theoretically these changes can be made, it would require significant coordination work with the
architect and other disciplines and there is no guarantee that the spatial requirements would be able to be accommodated.
The lighting design for the Collins Arch project was found to be compliant with the proposed requirements of 2019 with
the exception of the lighting power density in the hotel and commercial lobbies and hotel standard rooms. Compliance
could be achieved in this instance through reducing the lighting installed and no cost addition would be expected,
however the amenity of the spaces may be impacted.
The lifts proposed for the building are expected to be compliant with the 2019 requirements.
The building and services were found to be generally in accordance with the new provisions of Section J of the NCC
2019. Minimal cost impact is expected to make minor changes to the systems design to meet the more prescriptive
provisions of Parts J5 and J6.

7 COMMENTARY ON THE NEW
SECTION J PROVISIONS 2019
7.1 PARTS J1-J2 BUILDING FABRIC
The following items are general concerns on wording and clarity that we believe should be incorporated into the code.
SECTION COMMENT RECOMMENDED RESOLUTION
Wall-glazing construction
J1.5 (d) (iii)
Doesnt clearly indicate that these
are wall only R-Value
requirements and whether they
apply to the total wall for each
level and orientation or for each
wall element.
Indicate whether this is a wall only value
and whether it should be a minimum for
each wall element or an average for each
level and orientation.
Wall-glazing construction
J1.5
No worked example for
calculating thermal resistance
values of entire facades. This
could be a source of confusion as a
faade with 50% at R1 and 50% at
R2 is total R1.33.
Provide a worked example on how to sum
R/U-values and SHGCs for a faade in
order to provide clarity.
Wall-glazing construction
J1.5 (d) (ii)
Lack of precise description of
used to display retail goods in a
shop or showroom has potential
to reduce stringency to all retail
buildings.
Provide a clear definition of this term
including the maximum level of
occupancy required (if any) for this term to
applicable to a project.
Wall-glazing construction
J1.5
Division of requirements for
specific class types only ignores
the extra thermal requirements of
overnight operating buildings in
classes other than Class 3 or 9c
building or a Class 9a ward area.
Recommend returning to a previous issued
draft distinction of the two provisions
which divided the buildings based upon
hours of overnight use.

basement and retaining wall elements as
Section 3.5 also includes a calculation
method for basement walls.
7.2 PART J5 MECHANICAL SERVICES
This section intends to highlight the major positive and negative impacts of the NCC 2019 founded upon the results of
this case study.
- Positives
o J3.5(c) Allows building designers to enforce contractors to adhere to good building practices in regardto building sealing.
o J5.2(a)(iii) An improvement to the original criteria for economy cycles; however, could use more
clarification on what consists of an airside component of an air-conditioning system. i.e. do all the
FCU airflows added together entail an air-conditioning system, or do they only need to be considered
individually.
o J5.2(a)(x) Provides a low cost high impact solution for this project to allow for energy efficiency
opportunities if only one level of the building is being used outside of normal operating hours. It helps
ensure energy use during after-hours operation is kept to a minimum.
o J5.4(b) Provides a path to fan compliance for a variety of real world applications. The NCC2016 was
not friendly to fan selections in high pressure applications because efficiencies are measure in W/L/s,
regardless of pressure drop. The NCC2019 simply requires a motor efficiency. In this case study, the
kitchen exhaust fans were assumed to be non-compliant; however, these fans would become compliant
under the new requirements. Refer to appendix for more information.
o J5.7(c) Refer to J5.4(b).
- Negatives
o J5.4(b) The methodology for calculating fan efficiencies required is tedious, and requires a selection
before checking compliance. Therefore, the current process of selecting a fan is iterative. This process
could be made easier through manufacturer software integration. Checking compliance is one of the
most difficult aspects because a fan efficiency needs to be provided. Commonly, efficiencies arent listedon schedules, and not all manufacturers provide efficiencies in selections. If checking compliance is notmade simple, there is a risk this section of the code could be overlooked.
o J5.4(c) & J5.4(d) Requiring a designer to meet specific pressure drop requirements restricts design
flexibility whilst not necessarily increasing overall building efficiency. Whilst the specified pressure
drops are in-line with good industry practice, there are times where components would need to exceed
the limitations for practical reasons (i.e. spatial issues, cost). It may be more beneficial to shift this
part of the code to the Australian Standards to be enforced as guidelines.
o J5.7(c) Refer to J5.4(b).
o Table J5.8(a) The piping insulation requirements for pipework between 30C and 85C (typical
heating hot water and refrigerant systems) has nearly tripled in R-value. Small refrigerant piping and
branch piping to hot water coils would need to increase significantly in size, potentially from 25mm to
75mm. This increase could potentially triple the pipework insulation cost, and it will greatly impact on
ceiling void coordination. Whilst this increase strives for energy efficiency improvements, it may not bepractically realised in a real world installation. The theoretical losses from the current insulation
requirements are low enough such that temperature drops through a system are considered negligible.

7.3 PART J6 ELECTRICAL SERVICES
The more stringent lighting illumination power density requirements proposed for the 2019 amendment appear adequate
for functional lighting for the areas that have been tested. The spaces tested for this case study showed non-compliances
for areas subject to a focus on architectural lighting. The proposed calculation methodology and illumination power
density limits will impact the ability to implement architectural lighting outcomes. As an area-weighted calculation
allowing some areas to exceed the power density limits over an entire project, there will be the ability to employ
architectural lighting solutions in select and limited areas on projects.
The architectural lighting tested for the hotel included floor level, wall panel and ceiling illumination in the hotel foyer,
and in the hotel rooms, the lighting included lamps, and display lighting that can be controlled by the lighting control
system. Some potential perverse outcomes of a more stringent lighting limit may include lamps being powered from
GPOs (not controlled), and vertical panel lighting treated as signage and similarly not as well integrated into the lighting
control system.
