2000/119 Building Amendment Regulations 2000 r 4

Explanatory note

This note is not part of the regulations, but is intended to indicate their general effect.

These regulations, most of which come into force on 31 October 2007, amend the Building Code set out in Schedule 1 of the Building Regulations 1992 to increase the thermal resistance (insulation) performance requirements for housing. The objective of those requirements is to facilitate efficient use of energy. The new requirements are introduced in stages, and apply to the following climate zones on and after the following dates:

• 31 October 2007—climate zone 3 (the South Island, the Taupo and Ruapehu Districts, the Rangitikei District from just north of the 40th parallel, the Chatham Islands, Stewart Island, and other land territories, islands, and islets south of the 42nd parallel):
• 30 June 2008—climate zone 2 (land territories, islands, and islets within the internal waters of New Zealand but not in climate zone 3 or climate zone 1):
• 30 September 2008—climate zone 1 (specified Northland, Auckland, and the Thames-Coromandel districts in the North Island, the Kermadec Group of Islands, and other land territories, islands, and islets north of the 42nd parallel).

Regulation 4(1) amends clause A2 by substituting a new definition of building performance index (BPI). The new definition—

• uses an updated annual loss factor design tool (ALF3); and
• calculates a building's insulation performance by reference not only to its total wall area; and
• assesses a building's performance by reference to the mean monthly temperatures in the locality in which it is situated.

Regulation 4(2) inserts in clause A2 new definitions of terms used in calculating a building's building performance index or the building's old measure building performance index (which will still be used, for transitional purposes, until 30 September 2008).

Regulations 5 to 7 substitute new clauses H1.3.2A, H1.3.2C, and H1.3.2E, and related limits on application. These new clauses require housing to achieve, in the staged way outlined above, increased thermal resistance performance requirements. The effect is to require enhanced insulation (for example, double-glazing).

Regulation 8 is a savings provision for building work that requires a building consent and is covered by an application, made before the new requirements commence, for a building consent or a certificate of acceptance. The Building Code continues to apply to that building work as if these regulations had not been made.

These regulations do not arise from the report on the review of the Building Code required by section 451 of the Building Act 2004.

Issued under the authority of the Acts and Regulations Publication Act 1989.

Status of Compliance Documents

Compliance Documents are prepared by the Department of Building and Housing in accordance with section 22 of the Building Act 2004. A Compliance Document is for use in establishing compliance with the New Zealand Building Code.

A person who complies with a Compliance Document will be treated as having complied with the provisions of the Building Code to which the Compliance Document relates. However, a Compliance Document is only one method of complying with the Building Code. There may be alternative ways to comply.

Users should make themselves familiar with the preface to the New Zealand Building Code Handbook, which describes the status of Compliance Documents and explains alternative methods of achieving compliance.

Defined words (italicised in the text) and classified uses (small capitals) are explained in Clause A1 of the Building Code and in the Definitions at the start of this Compliance Document.

Document Status

The most recent version of this Compliance Document, as detailed in the Document History, is approved by the Chief Executive of the Department of Building and Housing. This Compliance Document is effective for building consents issued on or after 31 October 2007 and supersedes all previous versions of this document.

People using this Compliance Document should check for amendments on a regular basis. The Department of Building and Housing may amend any part of any Compliance Document at any time. Up-to-date versions of Compliance Documents are available from www.dbh.govt.nz
