  abstract

  CIBSE TM71: Measuring the Heat Transfer Coefficient of Buildings provides guidance on the measurement and application of building heat transfer coefficients. The HTC describes the overall rate at which heat is lost from a building and is a fundamental input to building energy calculations, heating system design, retrofit evaluation, and the assessment of building performance. There is growing recognition that the thermal performance of buildings in practice can differ significantly from that predicted by design calculations. As a result, interest in measuring HTC directly has increased across industry, government, and academia. New measurement approaches have emerged that can provide evidence of building performance under both test conditions and normal operation, creating opportunities to improve the accuracy of building assessments and reduce uncertainty in decision making. TM71 standardises terminology to enable comparability between the results of different test methods, and provides guidance on validation, uncertainty, reporting, and practical application. It is intended for professionals involved in the assessment, specification, regulation, construction, and retrofit of buildings, and aims to support the consistent and credible use of HTC measurements across the built environment sector.
