Abstract
Buildings are a huge carbon emitter. Efforts are being made to cut both embodied and operational carbon emissions to reduce the impact on the built environment. This study aims to compare the Life Cycle Carbon Footprint (LCCF) and LCC of two alternatives: refurbishment and radical replacement of an existing community centre building in Liverpool to identify options that could achieve significant CO2 emission reductions in an economically viable way. The calculation methods are standardised by the UK's RICS (Royal Institute of Chartered Surveyors) to overcome the limitations of LCAs undertaken in previous research. This refers to the Inventory of Carbon and Energy (ICE) database from which embodied calculation factors were extracted to get the greenhouse gases. While the operational emissions data were obtained from a thermal simulation through IES software. The results of this study showed that the refurbishment scenario is the best option since it emits 50% less GHG and reaches 64% lower costs compared to the new build case throughout the building’s life cycle. Such that the LCCF of the refurbishment scenario was 215,084.36 kgCO2e/m2 and its LCC £ 88,135.32, while the replacement scenario achieved 429,397.44 kgCO2e/m2 and £ 246,213.59. It can be deducted that to reach significant reductions in carbon emissions rates with a lower economic impact, refurbishment is preferable to demolition and new construction, even if the building shows several damages and defects, which suggests that the UK government should incentivise and encourage re-use for faster environmental rehabilitation.
