COMMERCIAL, FABRICATION : MEETINGS AND EVENTS

The National Fenestration Rating Council Research and Technology Committee completed the morning meetings July 21 by approving $7500 in funding to support a research project that will be carried out by the Insulated Glass Manufacturers Alliance, Ottawa, Ontario.

Greenbelt, Md.-based NFRC is hosting its summer meeting  in Baltimore July 20-23.

IGMA’s project will assist in developing an improved test method for measuring the gas loss rate from a sealed insulating glass unit (IGU) and to develop a test method using a standard size IGU.

NFRC board member Jim Larsen, Cardinal Glass Industries Inc., Eden Prairie, Minn., offered his support for funding IGMA’s research project, saying it will produce a significant return on investment by providing important research that NFRC needs to stay current with the industry.

The motion to provide the funding to IGMA passed with one abstention, according to a July 21 NFRC News Now report.

Latest on complex fenestration

In other meeting news, Steve Selkowitz, head, Building Technologies Department, Lawrence Berkeley National Laboratory, Calif., concluded the day’s program with a presentation on “complex” glazing, shading, and fenestration systems. Complex fenestration refers to fenestration coupled with attachments, such as awnings, shades and blinds.

Selkowitz, who serves on the NFRC board of directors, discussed a three-day workshop on complex fenestration that took place at LBNL in early June. The workshop covered the latest issues surrounding complex fenestration, including its role in annual energy performance.

The workshop also presented information on bi-directional scatter data function, or BSDF, which includes both reflectance and transmission information through complex glazing systems. BSDF provides a way to characterize all angles of solar incidence.

Selkowitz said getting on a pathway to developing ratings for complex fenestration systems will require:

  • Defining/redefining users and their needs.
  • Starting with existing simulation tools.
  • Adding/developing new simulation capabilities.
  • Enhancing characterization capabilities.
  • Developing target audience tool interfaces.
  • Deploying, testing, and evaluating projects.
  • Building an infrastructure.
