Information on the energy efficiency of homes across Wales is helpful for policy makers as evidence for fuel poverty, energy strategy and green initiative policies. In the Data Science Unit, we have been working on a project to build a stronger evidence base for the energy efficiency of Welsh homes.

The most up-to-date source of information available on the energy efficiency of homes is the Energy Performance Certificates (EPC) Register. The Register, however, only covers half of all homes in Wales and is overrepresented by newer, more energy efficient homes. This is because legislation was introduced in 2008 that made EPC surveys a mandatory requirement when selling or renting a property.

This blog describes how we have been using the register of Energy Performance Certificates (EPC) to build a dataset that covers every residential property in Wales. This work builds on a project undertaken by the Office for National Statistics’ Data Science Campus: Using machine learning to predict energy efficiency | Data Science Campus.

Introduction

In 2022 Welsh Government began the process of compiling and publishing a set of Supply and Use (SUTs) and Input-Output Tables (IOTs) for Wales. These were to be the first holistic picture of the Welsh economy produced following Scotland (which has published SUTs and IOTs for decades) and Northern Ireland (which has done so for the post EU exit period).

The publication was intended to improve our understanding – inside and outside Welsh Government – of how the Welsh economy ‘worked’ in terms of production, trade and product use. More importantly, it was to determine whether collating such a picture – consistently, across all products, industries and users – was feasible, whilst guaranteeing a reasonable level of quality and robustness. The project delivered an Input-Output publication for Wales (for base-year 2019), detailing the structures and activities of 55 industries in Wales, along with related product use and supply. The Supply and Use and Input-Output Tables (hereafter called IOTs for simplicity) have been published as official statistics in development, together with an extensive methodology document.

The Data Science Unit has recently been exploring potential uses of Generative AI. One project has developed a proof-of-concept tool that uses Generative AI to assist in editing text content. The aim of the tool was to:

  • support content designers in the Welsh Government by providing them a better draft to work from; and,
  • help everyone produce better content (we do not have enough content designers for all our content!)

The tool could save the content designers time, focus their skills on the more challenging problems and improve our written content.

When we published the Welsh language technology action Plan in 2018, our aim was to create technological advances that would enable us to use more Welsh in a wide range of situations. In February 2024, the then Minister for Education and Welsh Language published the final report on this Plan, looking back at our progress, including advancements in AI.

It’s been over a year since my last blog which covered how LoRaWAN is helping to fight crime and tackle climate change.

Since then, we have seen the Smart Towns programme flourish, with the team undertaking a significant amount of engagement, and hosting what is understood to be the first “Smart” conference focusing on towns, hosted in Wrexham (which ironically is a city!).
