SMETER Validation Methodology

Summary

The UK government aimed to improve the assessment of thermal properties in domestic buildings, facing a challenge in consistently validating diverse Smart Meter Enabled Thermal Efficiency Ratings (SMETER) technologies designed to estimate heat transfer coefficients (HTC). The National Physical Laboratory (NPL) developed a novel, technology-agnostic, surrogate-based validation methodology that generates realistic synthetic data from known ground-truth HTC values, enabling robust blind testing of various SMETER solutions. This methodology has been completed, and initial blind tests using the approach showed satisfactory results, with SMETERs performing within 5-10% variation of the ground truth, establishing a reliable tool for future validations.
