Contents
1 Title
These regulations are the Building Amendment Regulations 2007.
2 Commencement
These regulations come into force on 21 June 2007.
3 Principal regulations amended
These regulations amend the Building Regulations 1992, regulation 3 and Schedule 1 of which continue in force in accordance with—
(a) section 415(2)(a) of the Building Act 2004; and
(b) regulation 8(2)(a) of the Building (Forms) Regulations 2004.
4 New clause E2 of Schedule 1 substituted
Schedule 1 is amended by revoking clause E2 and substituting the following clause:
Clause E2—External moisture
Provisions Limits on application Objective E2.1 The objective of this provision is to safeguard people from illness or injury that could result from external moisture entering the building. Functional requirement E2.2 Buildings must be constructed to provide adequate resistance to penetration by, and the accumulation of, moisture from the outside. Requirement E2.2 does not apply to buildings (for example, certain bus shelters, and certain buildings used for horticulture or for equipment for washing motor vehicles automatically) if moisture from the outside penetrating them, or accumulating within them, or both, is unlikely to impair significantly all or any of their amenity, durability, and stability. Performance E2.3.1 Roofs must shed precipitated moisture. In locations subject to snowfalls, roofs must also shed melted snow. E2.3.2 Roofs and exterior walls must prevent the penetration of water that could cause undue dampness, damage to building elements, or both. E2.3.3 Walls, floors, and structural elements in contact with, or in close proximity to, the ground must not absorb or transmit moisture in quantities that could cause undue dampness, damage to building elements, or both. E2.3.4 Building elements susceptible to damage must be protected from the adverse effects of moisture entering the space below suspended floors. E2.3.5 Concealed spaces and cavities in buildings must be constructed in a way that prevents external moisture being accumulated or transferred and causing condensation, fungal growth, or the degradation of building elements. E2.3.6 Excess moisture present at the completion of construction must be capable of being dissipated without permanent damage to building elements. E2.3.7 Building elements must be constructed in a way that makes due allowance for the following: (a) the consequences of failure: (b) the effects of uncertainties resulting from construction or from the sequence in which different aspects of construction occur: (c) variation in the properties of materials and in the characteristics of the site.
5 New clause F4.3.4(h) of Schedule 1 added
Clause F4.3.4 of Schedule 1 is amended by adding the following paragraph and limit on application:
(h) Be constructed so that they are not readily able to be used as seats. Performance F4.3.4(h) does not apply to Housing.
6 New clause F6 of Schedule 1 substituted
-
(1) Schedule 1 is amended by revoking clause F6 and substituting the following clause:
Clause F6—Visibility in escape routes
Provisions Limits on application Objective F6.1 The objective of this provision is to help safeguard people from injury in escape routes during failure of the main lighting. Functional requirement F6.2 Specified features in escape routes must be made reasonably visible by lighting systems, other systems, or both, during failure of the main lighting. Requirement F6.2 does not apply to Detached Dwellings, household units within Multi-unit Dwellings, Outbuildings, or Ancillary buildings. Performance F6.3.1 Specified features in escape routes must, when the systems for visibility are at their design level, be reasonably visible. Performance F6.3.1 does not apply to specified features in the initial 20 metres of an escape route if the risk of injury, or impediment to movement of people, due to the specified features not being visible is low for example, because people are familiar with the escape route, the escape route is level, and people do not require assistance to escape). F6.3.2 The systems for visibility must operate to the following percentages of their design levels within the following times after failure of the main lighting: (a) 80% in 0.5 seconds in locations (examples of which are given by performance F6.3.3) where there is a high risk of injury due to delay in operation of the systems for visibility; and (b) 10% in 0.5 seconds, and 80% in 30 seconds, in stairs and in locations that are unfamiliar to users; and (c) 10% in 20 seconds, and 80% in 60 seconds, in all other locations. F6.3.3 Examples of locations (referred to in performance F6.3.2(a)) where there is a high risk of injury due to delay in operation of the systems for visibility include: (a) areas where dangerous machinery is installed: (b) areas where hazardous processes take place: (c) clinical areas of hospitals: (d) prisons and other buildings in which people are detained: (e) any part of an escape route designed for use at any time by more than 250 people. F6.3.4 The systems for visibility must operate continuously in buildings or parts of buildings in the following risk groups for the following periods after failure of the main lighting: (a) risk group A, until restoration of the main lighting system: (b) risk group B, 90 minutes: (c) risk group C, 30 minutes. F6.3.5 Despite performance F6.3.4, if a building or part of a building falls into both risk group A and risk group B, the systems for visibility must operate for whichever is the longer of the periods specified in performance F6.3.4(a) and (b). F6.3.6 Signs to indicate escape routes must be provided as required by Clause F8 “Signs”
.(2) Clause A2 of Schedule 1 is consequentially amended by inserting the following definitions in their appropriate alphabetical order:
reasonably visible, in relation to a specified feature, and for the purposes of Clause F6, means that the specified feature is visible to a person who—
(a) is 10 metres from it, or the greatest distance from it that it is possible to go in the open space surrounding it, whichever is the lesser; and
(b) has sight that is not defective, or is corrected (for example, by an optical appliance).
risk group A, for the purposes of performance F6.3.4 and performance F6.3.5, means buildings—
(a) whose occupants are required to remain in the building until the main lighting system is restored; or
(b) whose evacuation time is longer than 90 minutes.
risk group B, for the purposes of performance F6.3.4 and performance F6.3.5, means buildings—
(a) whose evacuation time is 30 minutes or longer but not longer than 90 minutes; or
(b) whose occupant load is more than 1 000.
risk group C, for the purposes of performance F6.3.4, means buildings not in risk group A or risk group B.
specified features, for the purposes of Clause F6, means the following
(a) building elements that may act as obstructions:
(b) safety features required under clauses of this code other than Clause F6 (for example, handrails required under Clause D1):
(c) changes in direction:
(d) stairs and ramps:
(e) escape doors:
(f) entries to a safe place.
(3) Clause C2.3.3 of Schedule 1 is consequentially amended by revoking paragraph (f) and substituting the following paragraph:
(f) Provided with systems for visibility during failure of the main lighting, as required by Clause F6 “Visibility in escape routes”
, and(4) Clause F8.3.3 of Schedule 1 is consequentially amended by revoking paragraph (b) and substituting the following paragraph:
(b) Remain visible during failure of the main lighting for the period required by performance F6.3.4 and performance F6.3.5. (5) Schedule 1 is consequentially amended by revoking the limit on application related to clause G8.3 and substituting the following limit on application:
Performance G8.3 does not apply during a failure of the main lighting, when the requirements in Clause F6 “Visibility in escape routes”
apply.
