Whole life carbon assessment for the Hampden regeneration project
Assessing the carbon output of upgrading existing buildings versus demolition and replacement
We carried out a carbon assessment for the Hampden regeneration project, comparing the carbon output between converting and upgrading the existing building compared to demolishing and replacing what’s there.
Two options were modelled in a comparative whole life carbon assessment. The first looked at retaining and retrofitting the existing three and four-storey flats – applying a benchmark retrofit equivalent to abc’s Burdie House Drive project. The second looked at demolition impacts, with a replacement of two new four-storey blocks using RICS-based benchmarks, electric heating, and photovoltaic installations.
This assessment identified the carbon implications of both retrofit and new-build options, providing the evidence-base for decision-making by balancing carbon performance, cost, and user outcomes.
