From PROBE to net zero: A study of soft landings’ contribution

Abstract

This study reviews Soft Landings (SL) implementations, focusing on its role in achieving Low and Net Zero Emission (LZE) buildings and reducing the energy performance gap. With buildings contributing significantly to global carbon emissions, it is crucial to understand the effect of integrating approaches like SL for meeting Net Zero goals. Notably, this research identified that the extended 3-year aftercare phase of SL does not always lead to reduced operational carbon emissions. While SL promotes collaboration and structured delivery, its overall impact on consistently achieving LZE buildings remains unclear, largely due to insufficient in-use performance data. The paper advocates for integrating SL with other performance-based methods, emphasising the need for enhanced industry collaboration and data sharing to augment the understanding and effectiveness of SL in delivering LZE buildings. Practical Application This paper offers a thorough analysis of the Soft Landings (SL) framework in achieving Low and Net Zero Emission (LZE) buildings. It examines barriers at each project lifecycle stage and evaluates SL’s effectiveness through case studies, revealing inconsistencies in reducing operational emissions. The findings emphasise integrating SL with performance-based initiatives and enhancing industry collaboration and data sharing. Built environment professionals can leverage these insights to improve project delivery, optimise building performance, and achieve LZE goals more effectively.
