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 are explained in Clauses A1 of the Building Code and in the Definitions at the start of this Compliance Document.

5 Clause H1 of code (energy efficiency provisions) replaced

The First Schedule of the principal regulations is amended by revoking clause H1, and substituting the following clause:

Clause H1—Energy efficiency provisions

Provisions Objective H1.1 The objective of this provision is to facilitate efficient use of energy. Functional requirement H1.2 Buildings must be constructed to achieve an adequate degree of energy efficiency when that energy is used for— (a) modifying temperature or humidity, or both; or (b) providing hot water to sanitary fixtures or sanitary appliances, or both; or (c) providing artificial lighting Performance H1.3.1 The building envelope enclosing spaces where the temperature or humidity (or both) are modified must be constructed to— (a) provide adequate thermal resistance; and (b) limit uncontrollable airflow. H1.3.2 Buildings must be constructed to ensure that the building performance index does not exceed: (a) 0.13 kWh in a warm location; and (b) 0.12 kWh in a cool location.

Limits on application Objective H1.1 applies only when the energy is sourced from a network utility operator or a depletable energy resource. Requirement H1.2(a) does not apply to assembly service buildings, industrial buildings, outbuildings, or ancillary buildings, or to plant and equipment provided to modify temperature, humidity, or both. Requirement H1.2(c) applies only to commercial buildings and communal non-residential buildings whose floor area is greater than 300 m3. Performance H1.3.2 applies only to housing.

Provisions	Limits on application
H1.3.3 Account must be taken of physical conditions likely to affect energy performance of buildings, including— (a) the thermal mass of building elements; and (b) the building orientation and shape; and (c) the airtightness of the building envelope; and (d) the heat gains from services, processes and occupants; and (e) the local climate; and (f) heat gains from solar radiation.
H1.3.4 Systems for the heating, storage, or distribution of hot water to sanitary fixtures or sanitary appliances must, having regard to the energy source used,— (a) limit the energy lost in the heating process; and (b) be constructed to limit heat losses from storage vessels, and from distribution systems connected to storage vessels.	Performance H1.3.4(b) applies only where individual storage vessels are 700 litres or less in capacity.
H1.3.5 Artificial lighting fixtures must— (a) be located and sized to limit energy use, consistent with the intended use of space; and (b) be fitted with a means to enable light intensities to be reduced, consistent with reduced activity in the space.	Performance H1.3.5 does not apply to lighting provided solely to meet the requirements of clause F6.
