Research Subcommittee Meets this Morning

Research and Technology Committee Chair Werner Lichtenberger of TruSeal Technologies took to the podium this morning and called the Research Subcommittee to order.

NFRC Technical Services Manager Ray McGowan began by giving an update on the research budget and the status of active and potential future projects. Project task group chairs then gave a more detailed report of ongoing research.

Willie du Pont of Sunergy Consulting gave a full report of on the status of the Window 6/Therm 6 Validation research project, for use in determinging the solar heat gain coefficients (SHGC) and U-factors of complex glazing.

The new Window 6/Therm 6 software Lawrence Berkeley National Laboratory released has new features that can calculate the SHGC and U-factor of woven shades, venetian blinds and fritted glass.

According to DuPont, the group has completed the literature search and is in the middle of performing tests for SHGC and U-Factor and is about to begin the simulations.

“I’m very grateful to the NFRC membership," said du Pont. “Many of you gave test specimens and actual windows, and we’re very appreciative for the manufacturers' donation to this project.”

Willy mentioned there is one layer of glazing still needed, one with properties of shade.
