We are excited to share groundbreaking news of two new European Standards for in-situ testing of building thermal performance:
- EN 17887 1:2024: Thermal performance of buildings – In situ testing of completed buildings – Part 1: Data collection for aggregate heat loss test.
- EN 17887 2:2024: Thermal performance of buildings – In situ testing of completed buildings – Part 2: Steady-state data analysis for aggregate heat loss test.
These standards, designed for both new and existing domestic buildings, offer robust methods for measuring whole building heat loss, effectively functioning as a whole building U-value.
These new standards were developed through a collaborative effort led by Professor David Johnston at Leeds Beckett University and Professor Richard Fitton from Energy House Labs, with valuable contributions from experts across Europe. They will be implemented by national standardization bodies in 34 countries, including major European nations and the UK.
We are proud to see our team leading the way in establishing these important benchmarks for building performance measurement. Professor Fitton highlighted that these standards provide a significant advancement for those currently using the Co-heating method to assess building performance. Based on pioneering work by Leeds Beckett University, the standards now include detailed guidance on uncertainty and data collection, ensuring a harmonized approach across the European Union and UK.
