Case Study

Urban Scale Retrofit

A collaborative paper with contributions by the Scenario Modelling team will be presented at the 13th International Conference of the International Building Performance Simulation Association, in Chambery, France, in August.

The paper entitled Modelling urban Scale retrofit, pathways to 2050 low carbon residential building stock brings together work by the LCRI Scenario Modelling for Low Carbon Wales, the EPSRC funded Retrofit2050 project, and the JISC-funded STEEV project.

The UK government has set an ambitious target of 80% reduction of carbon emissions by the year 2050. As part of this target, it is predicted that the emissions related to buildings in 2050 will need to be close to zero.

Local authorities in Wales share the responsibility of improving and maintaining building stock condition to certain levels of sustainability and promoting the deployment of  renewable energy schemes in their area.

The Welsh residential sector has a  larger share of hard-to-treat properties compared to the rest of the UK. There is currently no representative residential stock model for Wales, and studies quoted in literature model the region based on data from other parts of the UK. This bottom-up approach goes one step further to demonstrate the possibility of providing policy makers and stakeholders at the local level with valuable information on the potential for retrofit based on area specific data.

The results are visualised in a web application, to allow stakeholders to engage with the modelling process.

The research measures the impact of housing retrofit renewable technologies, occupant behaviour, and grid decarbonisation at a local authority scale, using the Neath Port Talbot County Borough Council area as a case study.

Dr Aliki Georgakaki from the LCRI’s Scenario Modelling team, said “We were really pleased to work on this collaboration, and the paper had very good reviews from the conference.”
