Specification 45 Modelling profiles for J1V5
S45C2Reference building sole-occupancy unit
The heating loads and cooling loads must be calculated for the reference building sole-occupancy unit in accordance with the following:
a) J3D7, for roofs.
b) J3D9, for wall-glazing construction.
c) J3D10, for floors.
d) J4D5, for roof lights.
e) Solar absorptance of 0.6 for external walls and roofs.
f) Open area of 3.8 x 10-4 m2 per m2 of zone façade area for façade air infiltration, separate to designed natural ventilation openings.
S45C3Proposed building and reference building
(1) The heating load, cooling load and energy value for J1V5(1) and (2) must be calculated for both the proposed building and the reference building sole-occupancy unit using the sameβ
a) heating load or cooling load limits, calculated using heating degree hours, cooling degree hours and dehumidification gram hours from Table S45C3a; and
b) energy value factors from Tables S45C3b and S45C3c; and
c) location, in accordance with S34C3(3); and
d) climatic data, using the Typical Meteorological Year weather files drawn from the years 1990 to 2015 published by CSIRO; and
e) adjacent structures and features; and
f) orientation; and
g) building form, includingβ
(i) roof geometry; and
floor plan; and
number of storeys; and
location, extent and configuration of ground floors and basements; and
the size and location of glazing; and
external doors; and
walls between or bounding sole-occupancy units; and
balconies; and
testing standards, including for insulation, glazing, water heater and unitary air-conditioning equipment; and
fabric and glazing, includingβ
thermal resistance of air films including any adjustment factors, moisture content of materials and the like; and
internal shading devices, including their colour and criteria for operation; and
system configuration and control of air-conditioning services and energy sources other than renewable energy generated on-site where present; and
capacity and water usage, for on-site domestic heated water systems, assumingβ
a consumption rate in accordance with Table A.6.2 of AS/NZS 4234 of 10 L plus 1.25 L per m2 of floor area per sole-occupancy unit per day; and
a seasonal load profile in accordance with Table A.6.3 of AS/NZS 4234; and
a water inlet temperature of the monthly ground temperature in accordance with Table A.8 of AS/NZS 4234; and
a water outlet temperature of 60Β°C; and
the same calculation method for standing losses; and
internal heating loads, in accordance with Table S45C3d; and
occupancy profiles, in accordance with Tables S45C3e, S45C3f, S45C3g, S45C3h, S45C3i, S45C3j, S45C3k and S45C3l; and
internal zoning, assumingβ
daytime air-conditioned zones include at least one living space and one dining space; and
kitchen zones are a separate zone using virtual wall partitions at all times, and are only air-conditioned if adjacent to an external façade; and
each bedroom is a night-time air-conditioned zone; and
all other zones, including pantries, corridors, en-suites, walk-in robes, bathrooms, toilets, laundries and adjacent roof space or basement are unconditioned; and
the same assumptions and means of calculating the temperature difference across air-conditioning zone boundaries; and
the same floor coverings, furniture and fittings density; and
the same internal artificial lighting illumination levels.
(2) Where present, the air-conditioning services, including all centralised domestic services infrastructure, of each sole-occupancy unit of both the proposed building and the reference building must be modelled withβ
in climate zone 2 to 8, a heating thermostat setting ofβ
20Β°C for all conditioned zones from 6:00 am to 12:00 am; and
18Β°C at all other times; and
a cooling thermostat setting ofβ
in climate zones 1, 2 and 3, 27Β°C for all daytime conditioned zones from 6:00 am to 11:00 pm; and
in climate zone 4, 26Β°C for all daytime conditioned zones from 6:00 am to 11:00 pm; and
in climate zone 5, 25Β°C for all daytime conditioned zones from 6:00 am to 11:00 pm; and
in climate zones 6 and 7, 24Β°C for all daytime conditioned from 6:00 am to 11:00pm; and
in climate zone 8, 23Β°C for all daytime conditioned zones from 6:00 am to 11:00 pm; and
in all climate zones, a constant cooling thermostat setting of 24Β°C for all night-time conditioned zones.
(3) Natural ventilation of each sole-occupancy unit of the proposed building and the reference building must be modelled with the sameβ
frequency of data output, being at least hourly; and
opening flow properties in accordance with Table S45C3m; and
wind pressure coefficients in accordance with Tables S45C3n and S45C3o; and
infiltration values, unless building sealing is verified using J1V4, in which case infiltration values equal to the intended building air change rate at 50 Pa divided by 20 may be used for the proposed building only; and
operation settings as follows:
openings must shut when the external dry bulb temperature is less than or equal to a temperature 1Β°C higher than the air-conditioning service cooling set point; and
openings must shut when the external dry bulb temperature is greater than or equal to a temperature 1Β°C lower than the air-conditioning service heating set point; and
openings must remain open for all hours of the year that do not meet the above closing conditions.
