The full argument end to end: what we build with, what it costs in carbon up front, how that compares with four alternative methodologies, and what happens to the verdict once fifty years of energy and durability are counted.
485 kgCO₂e/m² upfront, modelled object by object from the BIM. Benchmarked against the NZGBC reference building, typical in-situ concrete, precast, steel frame and mass timber — then extended across the full fifty-year life.
What each apartment actually costs to run, where that energy goes, and what independent BRANZ measurement says about the New Zealand homes we are comparing ourselves against.
Waste measured as a depth on the building's own footprint. Waiatarua sits at 51 mm against a 100 mm target — the weakest of the four projects, and why.
Floor-cycle times, plant hours and delivery movements, and how the production model converts programme speed into construction-stage carbon.
Total cost of ownership over twenty to fifty years, comparing in-situ concrete against precast and CLT on durability rather than build price.
