This Part applies to—
a Class 1 building; and
a Class 10a building; and
a Class 10b Open link in same pageswimming pool associated with a Class 1 or 10a building.
A heated water supply system must be designed and installed in accordance with Part B2 of NCC Volume Three — Plumbing Code of Australia.
Thermal insulation for central heating water Open link in same pagepiping and heating and cooling ductwork must—
be protected against the effects of weather and sunlight; and
be able to withstand the temperatures within the Open link in same pagepiping or ductwork; and
use thermal insulation material in accordance with AS/NZS 4859.1.
The central heating water Open link in same pagepiping provisions apply to systems designed to heat the building via water, such as a hydronic heating system.
Central heating water Open link in same pagepiping that is not within a Open link in same pageconditioned space must be thermally insulated to achieve the minimum material Open link in same pageR-Value in accordance with Open link in same pageTable 184.108.40.206.

Heating and cooling ductwork and fittings must—
be sealed against air loss—
by closing all openings in the surface, joints and seams of ductwork with adhesives, mastics, sealants or gaskets in accordance with AS 4254 Parts 1 and 2 for a Class C seal; or
for flexible ductwork, with a draw band in conjunction with a sealant or adhesive tape.
Duct insulation must—
abut adjoining duct insulation to form a continuous barrier; and
be installed so that it maintains its position and thickness, other than at flanges and supports; and
where located outside the building, under a suspended floor, in an attached Class 10a building or in a roof space—
be protected by an outer sleeve of protective sheeting to prevent the insulation becoming damp; and
have the outer protective sleeve sealed with adhesive tape not less than 48 mm wide creating an airtight and waterproof seal.
The requirements of Open link in same page(a) do not apply to heating and cooling ductwork and fittings located within the insulated building Open link in same pageenvelope including a service riser within the Open link in same pageconditioned space, internal floors between storeys and the like.
Ductwork within a fully insulated building may still benefit from insulation particularly when the system is only operating for short periods.
In some Open link in same pageclimate zones condensation may create problems with uninsulated ductwork and insulation should still be considered.

An electric resistance space heating system that serves more than one room must have—
separate isolating switches for each room; and
a separate temperature controller and time switch for each group of rooms with common heating needs; and
power loads of not more than 110 W/m2 for living areas, and 150 W/m2 for bathrooms.
5 W/m2 in a Class 1 building; and
4 W/m2 on a verandah, balcony or the like attached to a Class 1 building; and
3 W/m2 in a Class 10a building associated with a Class 1 building.
The Open link in same pageillumination power density allowance in Open link in same page(a) may be increased by dividing it by the Open link in same pageillumination power density adjustment factor for a control device in Open link in same pageTable 22.214.171.124 as applicable.
When designing the Open link in same pagelamp power density or Open link in same pageillumination power density, the power of the proposed installation must be used rather than nominal allowances for exposed batten holders or luminaires.
When illumination power density and one or more control devices are used, the adjustment factor is only applied to the space(s) served by the control device. The adjusted allowance for this space is then combined with the allowances for the remaining spaces using an area weighted average, which subsequently increases the allowance provided in Open link in same page(a)(i), Open link in same page(ii) or Open link in same page(iii).
When no control device is used, the adjustment factor is equal to 1.
Control device adjustment factors in Open link in same page(b) are only applied to the Open link in same pageillumination power density, not the design Open link in same pageillumination power density.
Halogen lamps must be separately switched from fluorescent lamps.
Artificial lighting around the perimeter of a building must—
be controlled by a daylight sensor; or
have an average light source efficacy of not less than 40 Lumens/W.
The artificial lighting around the perimeter of a building does not need to comply to a maximum power density as neither the lighting required or the area of the space can be easily defined. Instead, external lights are required to be controlled by daylight sensors or to be efficient.

A water heater in a heated water supply system must be designed and installed in accordance with Part B2 of NCC Volume Three — Plumbing Code of Australia.
Heating for a Open link in same pageswimming pool must be by—
a solar heater not boosted by electric resistance heating; or
a heater using reclaimed energy; or
a gas heater; or
a heat pump; or
a cover unless located in a Open link in same pageconditioned space; and
a time switch to control the operation of the heater.
A time switch must be provided to control the operation of a circulation pump for a Open link in same pageswimming pool.
Some jurisdictions may have requirements for a pool cover under the Smart Approved Water Mark Scheme.
Heating for a spa pool that shares a water recirculation system with a Open link in same pageswimming pool must be by—
a solar heater; or
a heater using reclaimed energy; or
a gas heater; or
a heat pump; or
a cover; and
a push button and a time switch to control the operation of the heater.
A time switch must be provided to control the operation of a circulation pump for a spa pool having a capacity of 680 L or more.
