Lessons learnt from embodied GHG emission calculations in zero emission neighbourhoods (ZENs) from the Norwegian ZEN research centre

Year: 2025

Type: article

Abstract: This article presents, evaluates, discusses, and extracts lessons learnt on the calculations methodologies and design choices relating to embodied greenhouse gas (GHG) emission calculations from zero emission neighbourhood (ZEN) case studies from the Norwegian ZEN research centre. In all, eight case studies are assessed, varying in size, phase of development, typology, and location. The embodied GHG emission results show life cycle modules B8 (24-75%), B6 (12-57%), and A1-A3 (20-38%) contribute the most to total GHG emissions, as well as the Building (24-91%), HVAC installations (15-30%), and Electric power (4-22%). In summary, more consistent calculation methodologies and system boundaries are required at the neighbourhood level to improve transparency, and further climate mitigation strategies are required to achieve a net zero GHG emission balance.
