This cleaned and validated CSV dataset of Irish domestic Energy Performance Certificates supports large-scale building stock energy modelling. The dataset comprises structured information extracted and refined from national building energy assessment records. It provides granular data points essential for evaluating domestic building performance across Ireland. The records include critical variables such as building fabric specifications, HVAC system configurations, total floor area, and assigned energy performance ratings. This structured format allows for the systematic analysis of thermal efficiency and operational energy demand in residential typologies. By standardising diverse certificate entries, the dataset enables researchers and practitioners to perform accurate statistical modelling of energy consumption patterns and identify trends within the national housing stock.

The download is a 64.7 MB file containing .CSV files.

Professionals typically ingest this CSV file into data analysis software, statistical packages, or custom energy simulation environments. Users can filter the records by specific building characteristics or geographic regions to inform urban-scale energy studies or retrofit planning. The data is structured for compatibility with standard spreadsheet applications and programming environments like Python or R, facilitating the rapid generation of energy performance distributions and benchmarking reports for large building portfolios or municipal policy development.

This dataset is primarily intended for urban planners, sustainability consultants, and architectural researchers working on residential retrofit strategies or national building stock analysis. It is highly effective for projects requiring evidence-based energy performance benchmarking, policy impact assessments, or the development of regional decarbonisation roadmaps. By providing a reliable foundation for comparative studies, the data assists in identifying common thermal deficiencies in existing housing, thereby guiding investment in energy-efficient upgrades and supporting the transition towards more sustainable urban residential environments.
