BS EN 17887-2:2024

This standard BS EN 17887-2:2024 Thermal performance of buildings. In situ testing of completed buildings is classified in these ICS categories:

• 91.120.10 Thermal insulation of buildings

This document specifies the steady-state data analysis methods to evaluate the data from ‘the aggregate heat loss test’. These analysis methods enable the actual in situ aggregate heat loss (building heat transfer coefficient) to be estimated. NOTE The aggregate heat loss method is specified in prEN 17887-1:2022 Thermal performance of buildings - In-situ testing of completed buildings - Part 1: Data collection for aggregate heat loss test.
