Construction waste generated

Of approximately 2223 kg of wastes generated by the construction of the NOW Home® in Rotorua, only 167 kg were diverted from the landfill. This represents approximately 8% of the waste generated. Expressed in terms of the overall floor area (141m2), 15.8 kg/m2 of waste was generated. According to larger US studies, typically for domestic construction, anywhere between 14.7 to 25.4 kg of waste is generated per square metre.

Waste from framing timbers is not included as the frames were made up off-site, generally regarded as being more resource efficient than onsite framing.  More timber waste was generated in the Rotorua NOW Home® than in the Waitakere NOW Home®, reflecting the considerably more complex roof/supporting (high) wall structure and the amount of extra timber needed to act as internal gutter support.

Plasterboard is the single largest (by weight) waste type by a considerable margin – accounting for 776 kg of waste in total.
