Regulation Impact StatementFor ConsultationAugust 2012 Proposal to address the problem of intrusive external noise in new residential buildingsThis Regulation Impact Statement (RIS), for consultation, accords with the requirements of Best Practice Regulation: A Guide for Ministerial Councils and National Standard Setting Bodies, as endorsed by the Council of Australian Governments in 2007. Its purpose is to inform interested parties of proposals to address external noise in residential buildings. Comments on this RIS are welcome.The Australian Building Codes BoardThe Australian Building Codes Board (ABCB) is a joint initiative of all levels of government in Australia, together with the building industry. Its mission is to oversee issues relating to health, safety, amenity and sustainability in building. The ABCB promotes efficiency in the design, construction and performance of buildings through the National Construction Code, and the development of effective regulatory and non-regulatory approaches. The Board aims to establish effective and proportional codes, standards and regulatory systems that are consistent between States and Territories. For more information see www.abcb.gov.au CommentsComments on this RIS are invited by 28 September 2012 and can be emailed to the ABCB at abcbris@.au with the subject title “External Noise RIS”.Copyright© Copyright 2012 Australian Government, States and Territories of Australia.

The effect of external noise is considered on a range of new residential buildings: Class 1 (houses), Class 2 (apartments), Class 3 (hotels / motels), Class 4 (caretakers’ rooms) and Class 9c (aged care facilities). These new residential buildings would be located in “noise affected areas” as designated under State and Territory legislation, essentially located close to major roads and railways. Around 13% of new residential buildings each year, or 50,000 prospective residents each year, are exposed to external noise which has the potential to become intrusive.There is clear evidence that intrusive external noise is harmful to residents, both from the perceptions of prospective residents and the burden of disease analysis by the World Health Organisation (WHO). To an extent this harm is already anticipated in the market and reflected in discounted prices for new residential buildings without adequate noise attenuation. The key question is whether prospective residents’ perceptions fully appreciate the potential harm from intrusive external noise and the noise attenuation features of the property they are considering purchasing.The objective, primarily, is to achieve health and amenity outcomes for residents of new buildings in noise affected areas, so that any noise intrusion levels in the living and sleeping areas do not compromise their heath or amenity. This RIS presents four alternative choices by decision-makers: the Status Quo plus three options to address the problem and achieve the primary objective:1. New NCC provisions for a range of residential buildings: Class 1 (houses), Class 2 (apartments), Class 3 (hotels / motels), Class 4 (caretakers’ rooms) and Class 9c (aged care facilities), to be enacted under State and Territory legislation in designated “noise affected areas”.2. New NCC provisions for Class 2 buildings (apartments) only, to be enacted under State and Territory legislation in designated “noise affected areas”.3. Handbook produced by the ABCB, providing a general performance objective and some suggestions for technical building solutions for a range of residential buildings, for reference and use on a case-by-case basis by State, Territory and Local Governments and the building industry.The options are evaluated relative to the Status Quo baseline. If these options would result in negative net-benefits, then this RIS will recommend the Status Quo. If positive net-benefits are possible, then this RIS will recommend the option with the highest net-benefits.Costings for Option 1, which are also utilised in Options 2 and 3, were prepared by a professional quantity surveyor (see Attachment 2). The assessment of costs simply 。
