Reference Procedure for Simulating Spandrel U-Factors

October 10, 2017

RDH Building Science is pleased to announce the release of a voluntary “Reference Procedure for Simulating Spandrel U-Factors”, a new and public resource prepared with the participation of the Fenestration Association of BC (FENBC) Technical Committee and the financial support of BC Housing under the Building Excellence Research and Education Grants Program.

The voluntary Reference Procedure is based on NFRC 100 and supplements that methodology to help fenestration manufacturers determine more realistic spandrel panel U-factors for compliance with whole building energy design standards such as ASHRAE 90.1 and the Canadian National Energy Code for Buildings (NECB). These standards require building designers to determine the effective U-factor of opaque wall assemblies clad with spandrel products, who often turn to fenestration suppliers to provide this information.

FENBC member companies found there was insufficient guidance in NFRC 100 for simulating spandrels, and particularly the narrow and interrupted Window Wall spandrels that are common in large buildings today. The lack of a recognized reference methodology was identified as an impediment in evaluating competing performance claims.

The voluntary Reference Procedure allows spandrel U-factor performance claims to be compared under standard conditions in the way that NFRC 100 window U-factors are compared today. It can also be used to determine U-factors at project sizes.
