1.6 Specific Application Requirements
The following applications of this document make specific compulsory requirements.
1.6.1 NABERS ENERGY Commitment Agreement
The purpose of simulation under the NABERS Energy Commitment Agreement is to provide a quantitative basis
upon which the risks of the building’s performance can be assessed. This requires that the simulation is, as far as
possible, a good representation of how the potential range of modes in which building will or may operate over
time.
All the requirements of this document must be met for an NABERS Energy Commitment Agreement.
particular:
In

The building is to be modelled as it is expected to operate. If this is unknown, default figures may
be used.

No specific restrictions on the simulation package are made. However, it is strongly
recommended that packages meeting the requirements identified for the Green Star Office Design
tool are considered.

Weather data shall be for a reference year data set for a local weather station representative of the
building. Weather data shall use actual recorded solar radiation, temperature and humidity data
from the local weather station and either be the ACADS-BSG/CSIRO Nominated Test Reference
Year for the nearest available climatic weather station, a Typical Meteorological Year (TMY) for
the location or other standard weather year. TRY formats are preferred where available.
Additional analysis is recommended to quantify the potential effect of ‘non average’ weather
conditions and climate change on future ratings.
1.6.2 Green Star Office Design Tool
The Green Star Office Design tool (“Green Star”) uses this document to endeavour to create a simulation
model that can be compared on an equitable basis against an absolute scale under standardised conditions.
As a result, the following specific compulsory requirements are made under Green Star when using this
document:
1. The default figures nominated in Section 5 of this document for occupant density, equipment
density, and operating schedules must be used.
2. Lighting density shall be modelled as per the design for base building lighting provided to NLA
and house areas with an extra allowance of 1 W/m² for tenants lighting to office floors. Lighting
shall be schedules as per the figures nominated in Section 5 for Lighting (limited control)
3. The building must be modelled with all lettable spaces fully occupied with diversity of occupation
as nominated in Section 5.
4. The simulation package must either:
