Description
2024 BES Session: Validating Thermal Performance of Existing Assemblies Using In-Situ Measurements
Course Overview
This session was originally presented at the 2024 IIBEC/OBEC Building Enclosure Symposium in Toronto, Canada. This course includes the following components:
- recording of the live session
- a summative assessment consisting of 10 questions
- two surveys required to claim continuing education credit
Description
For architects, engineers, and building owners, the thermal performance of existing or historic building envelopes is often difficult to determine with a high level of accuracy. To obtain greater baseline performance accuracy for energy models, especially for deep energy retrofit projects, in-field measurement tools can be used to obtain real-time data on the conductivity of the existing assemblies. This presentation will focus on the typical procedures of in-situ U-factor measurement, outline the capabilities and limitations of the tool set, and recommend ways to improve the validity of measurements using case studies. For older buildings, the records of existing assemblies are often incomplete or inaccurate. The in-situ U-factor measurement tool set is especially useful for architects and engineers when the status of the existing materials is unclear. For a documented assembly, these field measurements assist in validating the U-factor estimates. If the field-measured U-factor consistently varies from the calculated prediction, those measurements prompt further study. For an undocumented envelope, field measurement is an excellent nondisruptive method for building owners and their consultants to estimate the thermal performance of an existing envelope. Every measurement is different due to key factors such as weather conditions, interior boundary, thermal mass, etc.
