NSW Subsection J(A) Energy Efficiency - Class 2 Buildings and Class 4 Parts

PERFORMANCE REQUIREMENTS

NSW J(A)P1

(a)

Thermal insulation in a building must be installed in a manner and have characteristics, which facilitate the efficient use of energy for artificial heating and cooling.

(b)

A building must have, to the degree necessary, thermal breaks installed between the framing and external cladding, to facilitate efficient thermal performance of the building envelope.

Application

Application:
  1. NSW J(A)P1(a) only applies to thermal insulation in a Class 2 building or Class 4 part of a building where a development consent specifies that the insulation is to be provided as part of the development.
  1. In (a), the term development consent has the meaning given by the Environmental Planning and Assessment Act 1979.
  1. NSW J(A)P1(b) only applies to a metal framed roof and a metal framed wall.

NSW J(A)P2

A building must have, to the degree necessary, a level of building sealing against air leakage to facilitate the efficient use of energy for artificial heating and cooling appropriate to—

(a)

the function and use of the building; and

(b)

the internal environment; and

(c)

the geographic location of the building.

Application

Application:

NSW J(A)P2 only applies to a Class 2 building or Class 4 part of a building, except—

  1. a building in climate zones 2 and 5 where the only means of air-conditioning is by using an evaporative cooler; and
  2. a permanent building opening in a space where a gas appliance is located, that is necessary for the safe operation of a gas appliance; and
  3. parts that cannot be fully enclosed

NSW J(A)P3

A building's services must have features that, to the degree necessary, facilitate the efficient use of energy appropriate to—

(a)

the function and use of the service; and

(b)

the internal environment; and

(c)

the geographic location of the building; and

(d)

the energy source of the service.

Application

Application:

NSW J(A)P3 only applies to a Class 2 building or Class 4 part of a building.
