    (ii)there is insufficient work space for a person to install the insulation;

    (f)for electric resistance space heating elements cast into concrete or set under tiles—complying would involve physical changes to the elements.

  13. New section 24 (4)

    insert

    (4)In this section:

    insufficient work space—there is insufficient work space for a person to install a barrier or insulation unless—

    (a)there is space for the person to at least crawl along (on temporary support planks if necessary) and work in (lying flat if necessary) to safely install the barrier or insulation; and

    (b)the space is at least 600mm wide and 600mm high, apart from any obstacles intruding into the space; and

    Examples—obstacles

    access hatch, truss member, beam, pier

    NoteAn example is part of the regulation, is not exhaustive and may extend, but does not limit, the meaning of the provision in which it appears (see Legislation Act, s 126 and s 132).

    (c)any obstacles intruding into the space do not reduce the dimensions of the space to less than 450mm wide and 450mm high and are reasonably negotiable by a person used to working in confined spaces; and

  14. Section 28 (1)

    substitute

    (1)For section 24 (2), the alternative energy efficiency requirements for the unaltered part of a substantially altered building are as follows:

    (a)for the walls—the external walls in the unaltered part have a total R-value that complies with the applicable value stated in the building code, volume 2, part 3.12.1.4 (External walls);

    (b)for the roof—the roof in the unaltered part has a total R-value that complies with the applicable value stated in the building code, volume 2, part 3.12.1.2 (Roofs), adjusted as required under that part to compensate for insulation loss associated with any exhaust fans, flues or recessed down lights;

    (c)for a suspended floor—any suspended floor (excluding an intermediate floor in a building with more than 1 storey) in the unaltered part has a total R-value that complies with the applicable value stated in the building code, volume 2, part 3.12.1.5 (Floors);

    (d)any interface between a wall cavity and a suspended floor (excluding an intermediate floor in a building with more than 1 storey)—

    (i)is continuously bridged with bulk thermal insulation of loose mineral, glass or plastic fibres preventing convection air movement from the sub-floor area through the wall cavity to the roof space; or

    (ii)otherwise has a convection barrier that complies with the building code, volume 2, part 3.12.1.5 (Floors).

  15. Section 29 (1) and (2)

    substitute

    (1)External glazing in the unaltered part of a class 1 or class 10 building need not comply with the building code, volume 2, part 3.12.2 (External Glazing) if the transparent or translucent part of the glazing is coated, and permanently bonded, on at least 1 side with a continuous polymeric coating, sheet or film that achieves—

    (a)a total U value of 5.0 or less; and

    (b)a solar heat gain coefficient of 0.25 or less.

    (2)Isolated glazing in the unaltered part of a class 1 or class 10 building need not comply with the building code, volume 2, part 3.12.2 (External glazing).

    Example

    A house is to have a family room added, opening onto the existing kitchen, to form an integral kitchen-family room. External windows in the new family room must comply with the building code. There is to be no barrier between the kitchen and the new family room so the existing kitchen window is not an isolated window. Its impact on the new family room must be considered when considering how the new family room complies with the building code, volume 2, part 3.12.2. All other windows in the unaltered part of the house are in fully enclosed rooms, with close-fitting doors so they are isolated windows. In applying the building code to the new family room’s windows, the isolated windows do not need to be considered.

    NoteAn example is part of the regulation, is not exhaustive and may extend, but does not limit, the meaning of the provision in which it appears (see Legislation Act, s 126 and s 132).

  16. Section 29 (3), definitions of incidental glazing, glazing and relevant external glazing

    substitute

    glazing includes frame assemblies and transparent and translucent roof lights.

    isolated glazing means glazing in the unaltered part of a building that is thermally isolated from glazing in the altered part of the building by a barrier of—

    (a)unperforated floors, ceilings or walls; and

    (b)doors that are close-fitting (but not necessarily sealed).

    Example—par (b)

    internal French doors installed in ordinary door frames and to ordinary construction tolerances, without additional door seals or draft excluders

    NoteAn example is part of the regulation, is not exhaustive and may extend, but does not limit, the meaning of the provision in which it appears (see Legislation Act, s 126 and s 132).
