City Case Study - Wrexham

Welsh Government

Climate change is projected to increase temperature and change humidity and rain patterns in Wales and, more widely, across the UK.  Such climate patterns have the potential to alter the temperature, humidity, air quality and associated pollution levels, as well as the durability of the building envelope materials for homes throughout the country. To better understand these impacts a climate vulnerability analysis was performed by a collaborative team from Cardiff Metropolitan University and Resilient Analytics, a climate resilience consultancy based in Colorado, USA.

The Wales Housing Climate Analysis shows climate projections, indoor air quality, thermal comfort and building fabric vulnerability results for each Welsh county as well as more detailed case studies for three cities and one town.

Climate projections, indoor air quality, thermal comfort and building fabric vulnerability results are presented here for Wrexham.  Accompanying maps in this series can be found here:

Climate Projections consisting of Daily Maximum Temperature, Annual Precipitation, Daily Relative Humidity and Daily Specific Humidity

Indoor Conditions results consisting of Indoor Air Quality and Overheating

Building Fabric degradation results consisting of Solar Insolation, Precipitation and Relative Humidity 

Case Studies for four representative towns and cities illustrate results at a resolution of 2.2 km, giving insight into the variation that is projected geographically across each area:

Aberystwyth consisting of Climate, Indoor and Fabric

Cardiff consisting of Climate, Indoor and Fabric

Swansea consisting of Climate, Indoor and Fabric

Wrexham consisting of Climate, Indoor and Fabric
