There is no universal best direction for pergola louvers. Position and blade direction should respond to latitude, hemisphere, façade orientation, seasonal sun angles, the time the terrace is used, surrounding shade, views and drainage. Model the real site first; then choose the roof orientation and control zones that deliver the intended daylight rather than following a generic compass rule.
Start with the hours that matter
Mark where occupants sit and when the space is used. Morning breakfast, midday pool use and late-afternoon dining receive different sun angles. Low sun from the side may pass below an overhead roof even when the louvers provide strong shade above.
Photograph the site at useful times or use a location-based sun-path study. Include nearby walls, trees, parapets and upper floors because they can matter more than compass direction alone.
- Project latitude and hemisphere
- Façade and terrace orientation
- Season and daily operating hours
- Low-angle east or west sun
- Existing trees and buildings
- Desired view and privacy
Louver direction changes the experience
Rotating blades can admit, reflect or block direct light according to their axis and opening direction. The same blade layout may work differently beside glazing than over an isolated seating area. Roof movement also affects the view upward and the way daylight reaches the interior room.
Direction cannot be chosen only for shade. It must remain compatible with beam layout, span, drive position, gutter collection, module joints and the selected LUCY model.
| Priority | Review before fixing direction |
|---|---|
| Shade | Sun angle during the hours of use |
| Indoor daylight | Distance and orientation of adjacent glazing |
| View | Blade sightlines in open and closed positions |
| Ventilation | Open-roof airflow and surrounding walls |
| Rain management | Louver collection direction, gutters and outlets |
| Multi-module layout | Consistent roof, beam and drainage coordination |
When side shading is still needed
An adjustable roof manages overhead sun but cannot stop every low-angle ray. ZIP screens, louver walls, planting or architecture may be useful on selected elevations. Add them only after reviewing wind exposure, circulation, power, drainage and safe operation.
For restaurants and hotels, divide large terraces into zones so staff can change shade without moving the entire roof at once. Confirm how the controls are labeled and who is responsible for weather procedures.
A practical orientation brief
Send a north arrow, location, plan, photographs, façade openings and intended use. Mark the preferred post-free edges and any view that must remain open. LUCY can then compare roof direction and model configuration while the local designer confirms solar and planning requirements.

- Preferred seating and circulation
- Doors, windows and indoor rooms
- Critical morning or afternoon periods
- Roof movement preference
- Screens, lighting and drainage constraints

Common questions
Should louvers always run east to west?+
No. The useful direction depends on the actual sun path, use times, façade, roof system and drainage.
Can louvers block late-afternoon sun?+
They help overhead, but low-angle sun may require a side screen or another shading layer.
Will a pergola darken the room behind it?+
It can. Adjustable louvers offer more control, but geometry and façade orientation should be reviewed.
Can different modules use separate controls?+
Potentially. Confirm motors, control zones and the approved electrical package for the selected system.
