Simulations of a Typical Office Installation
The following simulations show the effects of different glazings on video display terminal glare, etc.
About the Office Animation
Physical Setup of the Office and Simulation
(3.8 MB MPG)
- Office room dimensions: 10 feet wide (N-S) by 20 feet long (E-W)
- Glazing Clear opening dimensions: 10 feet by 5.75 feet
- West facing glazing three floors above street level
- CIE Clear skies with direct sun
- Building located in San Francisco (37.8 N latitude, 122.4 W longitude) in a mid-rise, office/industrial neighborhood
- Electrochromic device time sequence and spectral transmittance and reflectance measurements based 1 foot square prototype Tungsten Oxide (WO3) devices provided by industry-leading glazing manufacturers.
- Dynamic exposure compensation with pcond foveal-weighted averaging applied to each frame
Sequence of Events
- 15:00:00, sun obscured by a cloud, glass at full transmittance: Tvis=74%
- 15:00:03, cloud moves away and direct sun enters the office
- 15:00:12, electrochromic glazing begins to color at its maximum rate
- 15:04:06 through 15:17:42, video is in 10X time lapse to prevent boredom
- 15:17:42, electrochromic glazing reaches its maximum coloration: Tvis=3.2%
- 15:17:48, the cloud moves in front of sun obscuring all direct sun
- 15:17:54, electrochromic glazing begins to bleach at its maximum rate
- 15:22:18, electrochromic glazing reaches its maximum bleached: Tvis=74%
