Seminar 89 -- Window Shading: How to Save Energy while Improving Occupant Comfort and Visual Environmental Quality?

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Window shading systems/attachments have the economic potential to save 800 TBTUs in cooling and heating energy by 2030, while they can also significantly enhance visual environmental quality in terms of glare and outside view preservation. Lack of performance rating mechanisms, including energy savings potential and comfort-related studies of various shading systems,prevent these systems from fully realizing their market potential. Recent developments in characterization and rating of shading systems, including energy performance, glare protection along-with novel combinations of repeatable workflows that allow practitioners to quickly evaluate fenestration systems for their energy performance, visual comfort, and view quality will be presented.
