The window is not the finished design
Daylight is often treated as a moral good: more is assumed to be better. Building guidance is less sentimental. The Whole Building Design Guide describes daylighting as a system that must balance daylight delivery with glare, heat gain, views, electric lighting controls, glazing, partitions, and interior finishes. A bright window directly behind a monitor can make the room look impressive while making the workstation unpleasant.
A small office study published in the Journal of Clinical Sleep Medicine found an association between workplace window exposure and longer sleep duration and better self-reported outcomes in its sample. That is useful evidence, not a universal promise. It supports designing for access to daylight and views while keeping the limits of one study visible.
Map the light at the desk
A serious audit asks where daylight lands, at what time, and on which task. Photograph or measure representative desks in the morning and afternoon. Record monitor reflections, direct sun on faces, contrast between the screen and the window, and whether blinds are actually usable. Check whether partitions block views or whether a deep floor plate leaves most seats dependent on electric light.
The remedy is usually a package: move screens away from direct glare, use adjustable shading, select appropriate glazing, distribute workstations through the daylight zone, and connect perimeter lighting to controls. The correct solution changes with climate, orientation, adjacent buildings, and the work being done. There is no responsible universal window-to-productivity ratio.
Where Vastu can add a useful layer
A directional tradition can prompt a client to ask how morning light, heat, and movement are experienced in a space. That conversation can be valuable when it leads to an actual observation. It becomes unsafe when an east-facing desk is declared healthy without checking glare, screen ergonomics, thermal comfort, or the person using it.
Use the language of direction to structure the walk-through, then use measurements and occupant feedback to choose the intervention. The goal is not to win an argument with the sun. It is to let people work without squinting at it.
