Wind speed claims need test/calculation context.
OUTDOOR ARCHITECTURE · WIND
Louvre pergola wind and cyclone planning.
A generic wind-speed number is not a complete structural design. Site wind criteria, terrain, building effects, geometry, foundations and operating state all matter.
SHORT ANSWER
Use exact-system wind evidence as an input to project engineering—not as a substitute for it.
Confirm destination/site wind criteria, pergola geometry, support/fixing conditions, roof operating state and surrounding building exposure. Then match an exact system with appropriate evidence and have the appointed local engineer design the site-specific structure/foundations.
KEY PROJECT POINTS
What should drive the decision.
These are project inputs, not substitute engineering or automatic product approvals.
Open vs closed louvres can change pressure and load paths.
Freestanding and wall-mounted systems transfer loads differently.
Cyclone regions require site-specific foundations/fixings.
Screens/doors can materially change wind loading.
Operating/storm procedures belong in handover.
Define the design wind environment
Use the project's local wind standard, terrain/topography, building height/exposure and engineer's criteria rather than a generic regional headline.
Match evidence to configuration
A test or calculation for one size, profile or support condition should not be extrapolated to a different configuration without engineering justification.
Coordinate enclosures
Closing screens, sliding doors or side panels can alter pressure equalisation and structural demand.
Plan the storm state
Projects should document louvre position, screen/door position, isolation and inspection procedure for severe weather.
PROJECT INPUTS
What to have ready before asking for the exact system.
A stronger brief shortens the gap between product interest and a useful technical/commercial response.

EVIDENCE BOUNDARY
Product wind evidence and project structural design are different evidence layers.
Apollo should publish exact-system test/calculation scope honestly, then require project-specific local engineering for the site, foundations, fixings and surrounding building conditions.
FAQ
Questions project teams usually need answered.
Is a pergola wind rating the same as a site design wind speed?
Not necessarily. The evidence method, configuration and boundary conditions matter.
Do screens change wind loading?
They can. Enclosures may materially alter pressure and load paths.
Does Apollo provide cyclone engineering?
Apollo can provide exact-system evidence and project inputs; local site-specific structural engineering remains with the appointed professional unless expressly included.
