The Technical Analysis for Window Attachments Workshop Report has been Released!

Posted by Webmaster on 1. October 2012 17:39

This past summer, the Building Envelope and Windows R&D Program held the Technical Analysis for Window Attachment Workshop on July 16th and 17th in Arlington, Virginia, invitiing window attachment stakeholders to participate in a facilitated session to meet two objectives:

  • Provide up to date information on window attachment performance assessment methods to stakeholders
  • Discuss with key stakeholders what is needed and what is available to properly characterize window attachment performance, including:
    • Test procedures
    • Simulation programs
    • Indices of performance
    • Product categories

A report has been released containing the results of the workshop, and can be found below. Please review the results and send any comments to wzalis@energetics.com. Happy reading!

    The Tech Analysis workshop looks like a productive step in accelerating market availability of window attachments that save energy.

    Some of the biggest opportunities lie OUTSIDE the window and it's encouraging to see this category represented.

    I'd like to see considered for evaluation:
    a) Functional shutters with various working surface designs in the mix,
    b) Solar Screens.  These are already proven successful in the sunbelt States.  Energy savings are significant.  The interior is darkened some while a view is maintained.  The screens are recommended for permanent installation (perhaps because they mount on a frame that is sound but that may not be robust enough for repeated seasonal removal?),
    c)Solar Grates.  These also mount outside the window and reduce electricity for a/c similar to solar screens.  The grates selectively reflect direct sunlight so that visible light enters the room washing it in diffused light while most infrared is absorbed outside.  The room is bright while maintaining a view under all lighting conditions.  Grates are stored in winter for free solar heating from sunlight.  Maintenance is nil over at least 8 seasons including high winds and storms.

    Also, I understand the Univ. of Central Florida has done work in window and window attachment analysis and may be a valuable resource/participant.

    krish:

    As regards grates the 8 seasons of experience have shown that neither storms nor removal for seasonal storage have been a problem.  Maintenance is nil.  It is one of the surprises of the design.  The structure is partly from the grate itself.  The frame attaches to the grate along the periphery and mainly aids in handling and appearance.  Some applications succeed with no frame at all.

    Thank you for the report. WD, it's good to know that these grates have shown great reliability through the past 8 seasons. Looking forward to these coming to market soon, we all need to save on energy costs!
