There is also a strong lineup of local speakers.

Other activities organized in conjunction with the event include a guided tour of some key sustainable buildings in the Auckland CBD, arranged for the afternoon before the one-day summit.

New online PV calculator

A new online calculator tells consumers whether installing a photovoltaic (solar) system will be cost-effective for them.

The calculator sits on the EECA’s Energywise website. It takes into account factors such as geographic region, roof slope, current electricity use and the cost of a PV system. It then gives an estimate of the years it would take for the cost of a PV system to be repaid, and the earnings or losses that would be incurred from installing a system.

The new tool was created by the University of Canterbury’s EPECentre through the GREEN Grid research programme, which is funded by MBIE, Transpower and the EEA. The calculator uses data from NIWA (the National Institute of Water and Atmospheric Research) through its SolarView service.

The calculator is designed for typical New Zealand homes and is not applicable for commercial buildings or off-grid installations.

Environmental label scheme now covers coated steel

Prepainted and resin-coated steel products that are more environmentally friendly can now carry the Environmental Choice label.

The environmental labelling programme Environmental Choice NZ (ECNZ) has released a new specification (EC-57) for prepainted and resin-coated steel products. This means that people specifying coated metal roofing, cladding, fencing, framing and guttering steel products have new help in selecting a product.

ECNZ already had a specification (EC-41) for flat and long steel products. The new spec expands that further along the production chain, to painting/coating and rollforming/pressing flat steel products.

The specification considers the life of the product from raw material extraction and processing, through coating application and forming, to transport, use, disposal or recovery/recycling. Chemicals and energy used and waste and emissions produced are taken into account.

Manufacturers whose products comply with the new spec can apply for a license to use the Environmental Choice label on their products.

New asbestos guidance

New guidance around managing and removing asbestos applies from 3 November 2016.

The new Approved Code of Practice: Management and Removal of Asbestos sets out how to comply with new legal requirements, including the Health and Safety at Work (Asbestos) Regulations 2016.

The Code of Practice replaces the existing New Zealand Guidelines for the Management and Removal of Asbestos (3rd Edition)

The Code can be used in court as evidence of whether or not someone complied with the requirements of health and safety law. Breaches of law can be costly – in 2015 a Christchurch company was fined $45,000 for failing to properly identify and manage asbestos at a demolition site.

Many building practitioners will come into contact with materials containing asbestos during renovation or demolition work. BRANZ has estimated that approximately 25,000,000 m2 of asbestos fibre-cement roof and wall claddings were installed on New Zealand buildings in the years 1945–1985.
