Development of skills To construct ENERGY EFFICIENT BUILDINGS

Transcription

1 The NATIONAL BUILDING REGULATIONS : Act 103 of 1977 To provide for the promotion of uniformity in the law relating to the erection of buildings in the area of jurisdiction of Local Authorities Development of skills To construct ENERGY EFFICIENT BUILDINGS The Government of South Africa and the Government of Switzerland recognise Climate Change as a fundamental risk to future development and livelihood. Based on the South African Long Term Mitigation Strategy the different options for Climate Change reductions have been assessed and it is acknowledged that Energy Efficiency is one of the most cost-effective mitigation options in South Africa. 1

2 Who and what is the NRCS? The National Regulator for Compulsory Specifications (NRCS) is a new public entity responsible to the Minister of Trade and Industry for administration of technical regulations. We consist of *Automotive, *Electro technical & Gaming, *Chemical, mechanical and materials as well as *Food Industries departments. The NRCS also administers the Trade Metrology Act and the National Building Regulations and Building Standards Act. Dr Rob Davies NRCS Mandate: Administer technical regulations in the interests of public safety and health or for environmental protection 2

3 The NRCS was created September 2008 Where in line do we with come WTO from? rules SABS PRIOR TO 2008 The Act transferred the Regulatory Division of the SABS and all regulatory functions of the SABS to a new statutory Department of Trade and Industry (DTI) - the National Regulator for Compulsory Specifications (NCRS).

5 The National Building Regulations old order and the Constitution The National Building Regulations & Standards Act was promulgated in South Africa became a fully democratic nation All legislation is subject to a Constitution The constitutional court has ruled that: although the NBR is seen as old order legislation, the NBR is the legislation that governs the building industry. Local authorities are increasingly challenged in administering the regulations. Skills and technical experience is scarce, and in most cases insufficient funds are available for effective enforcement. The role of local authorities is unclear and grossly under qualified and inexperienced municipal officials are expected to enforce technical legislation, resulting in lack of consistency in understanding and implementing the legal requirements for compliance with the law. On the positive side and despite administrative inefficiencies, the system does continue to work, albeit inefficiently, buildings are erected and projects are completed. 5

XA3 The requirements of sub-regulations XA1 shall be deemed to be satisfied when such building is designed and constructed in accordance with the following requirements: a) is the subject of a rational design by a competent person which demonstrates that the energy usage of such building is in accordance with SANS XA, or b) has an orientation, shading, services and building envelope in accordance with SANS XA; or c) has a theoretical energy usage performance determined by a competent person using certified thermal calculation software, less than or equal to that of a reference building in accordance with SANS XA. 25

32 Building Regulator is creating regulations that will ensure Efficient Water use in Buildings Water CARE How do we Reduce water demand? C: CONSERVE the water that is used. Valuable work has been done in quantifying flush volumes required for toilets. A Water Efficiency Labeling and Standards Scheme, which enables consumers to see the water efficiency rating of new taps, showers, toilets, urinals, clothes washing machines and dishwashers has to be enacted. A: ADD WATER to the water that is used. This is achieved by harvesting rain water. Rainwater tanks can provide a useful sole or supplementary water supply in most regions of South Africa. Rainwater can be used for toilet flushing, laundries or for watering the garden. Drinking rainwater is not advised in most areas of South Africa with potable supplies. If drinking water is being supplied by the rain tank, the system must be adequately maintained and health guidelines followed. RE: RE-USE WATER that has been used. This is recycling water already used. Black water, yellow water and grey water recycling proposed. 32
