Net zero emission buildings: a review of academic literature and national roadmaps

Addressing the growing issue of climate change demands active measures. With its significant carbon footprint, the building industry needs to make immediate efforts contributing to achieving the Paris Agreement’s objective of restricting global warming to 1.5 °C. This review focuses on net zero emission buildings (NZEBs) which are claimed to offer a viable option to significantly reduce greenhouse gas emissions from the built environment. The review covers both the recent academic literature on NZEBs, and the NZEB roadmaps from the member organizations of the World Green Building Council, focusing on those Green Building Councils actively working to implement NZEBs in their local contexts. By synthesizing a broad range of viewpoints and practices derived from academic literature and roadmaps, this review provides a holistic overview of the different perspectives to the current state of NZEBs and to their future. The review shows that NZEBs have the potential to provide significant environmental, economic, and social advantages, improving the built environment’s overall sustainability. The review also promotes a more thorough understanding over NZEBs that can facilitate collaborative policymaking and action amongst stakeholders.
