E2

‘E2 External moisture’ is a clause within the Building Code. Clause E2 requires the prevention of water that could cause undue dampness and damage to building elements. You can view and download the E2 Compliance Document in PDF for free, or purchase a copy in an alternative format. For further information about protecting buildings from external moisture, see our Weathertightness section.

Earthquake prone buildings 

In terms of the Building Act 2004 (section 122) a building is earthquake-prone if the building is likely to collapse in a moderate earthquake (taking into account its condition, the ground on which it is built, and its construction) causing injury or death to people in the building and nearby, and damage to other property. The provisions do not apply to single-storey residential buildings or household units of two or less units.  Building owners requiring more information should refer to the guidance on earthquake-prone buildings. See also our guidance to assist territorial authorities to develop policies on earthquake-prone buildings. Another useful resource is the New Zealand Society of Earthquake Engineers’ publication Assessment and Improvement of the Structural Performance of Buildings in Earthquake .

Education 

There are a number of building industry training programmes and courses for builders and building officials.

Energy efficiency 

Using products, systems, design or building methods that use less energy to do the same or better job than conventional products or systems. The Building Code clause dealing with energy efficiency is Clause H1. The Energy Efficiency and Conservation Authority (EECA)  has developed a website on how to save energy at home and work. See also ConsumerBuild for information on building ‘green’ homes using eco-friendly materials and systems.

Energy work certificate

A certificate given by a licensed electrician or gasfitter when they have completed a job to certify the work has been done in accordance with either the Electricity Act 1992 or the Gas Act 1992. You will need the energy work certificates to get a code compliance certificate where energy works were part of the building consent (section 19 of the Building Act 2004). For a list of publications about electrical and gas work including the Electricity Act 1992 or the Gas Act 1992, see http://newzealand.govt.nz  .

Engineering

The profession of, or work performed by, an engineer. Engineering involves applying scientific knowledge to the design and construction of buildings (including dams and bridges), machinery, etc. It is divided into branches including structural, civil, fire, electrical, mechanical and chemical. The Institution of Professional Engineers New Zealand (IPENZ)  is the professional body representing professional engineers in New Zealand. Engineers have certain functions under the Building Act 2004 specifically related to dam safety and fire. The Department publishes information, reports and advisories relating to structural engineering practice.

Exempt building work 

Building work not requiring building consent as defined in section 41 and Schedule 1 of the Building Act 2004. Exempt building work must still comply with the Building Code.
