Dynamic LCA potentially provides a more accurate way of accounting for carbon emissions and storage in building elements. It incorporates assessment of the role of time in accounting for carbon storage and emissions. It potentially provides a more policy-relevant and scientifically accurate method of carbon accounting than conventional methods that simply quantify all carbon emissions as being released at time “0” even if, in fact, the carbon is stored for many years prior to its release as carbon dioxide or methane.

This project applied the Dynamic LCA method to different materials used in NZ residential wall, floor and roof constructions, including consideration of the operational and end-of-life phases. The results are relevant to existing and futureinitiatives such as: the MBIE Building for Climate Change programme, EPD Australasia, BRANZ tools (such as CO2RE and LCAQuick), and other proprietary tools (e.g. EToolLCD, One Click LCA).

The project was funded by MBIE Building for Climate Change programme and BRANZ, and involved Massey University, BRANZ, Scion Research and École de Technologie Supérieure, Montréal.
