Trust receipt

Record schema 7. Model 2026.09.3. Prepared 2026-10-30. This is a model of the geometry it was given, not a forecast and not a building assessment.

  • Measured 1
  • Observed 2

Why this result

The bench in the shade is open for reading for an hour 9:00 AM to 2:00 PM and again 6:00 PM to 7:00 PM.

What you told it, and what it assumed

You told it

  • The place is called “The seat beside the driveway”, in Phoenix (demonstration), America/Phoenix.
  • Lengths are shown in feet and inches.
  • 1 private note is on this device. They stay in a project file unless you leave them out.

It assumed

  • Nothing in the counted geometry is marked as placed by the model.
  • Every counted object has some standing. That is not the same as every standing being a tape.
What it calculated

Calculated

  • The bench in the shade is open for reading for an hour 9:00 AM to 2:00 PM and again 6:00 PM to 7:00 PM.

What would change the answer

  • A taped dimension where the plan still says estimated, placed, or unknown.
  • Running the same change through a month that is not this one. A July gain is not a year.

Smallest next check

  • The next useful check is the object whose standing is still unknown or estimated, measured at the place.
Where it stops, and which sources it used

Stops

  • Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
  • Wall fixings, cantilever loads and wind class are an installer's responsibility, and a badly fixed awning takes render off a wall.
  • Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.
  • This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.

How The bench in the shade behaves in October

The bench in the shade is open for reading for an hour 9:00 AM to 2:00 PM and again 6:00 PM to 7:00 PM.

About 6 hours in October, and what it feels like is what closes it.

Read for 30 October 2026, in America/Phoenix, northern hemisphere. This is the day the place is reading, not the fifteenth that stands in for the month, and not a forecast for that date.

The sun reaches this spot from 2:00 PM and leaves it at 5:20 PM. The bench in the shade comes back into the sun at 1:47 PM, once the Deep eave is no longer in the way. The bench in the shade loses the sun at 5:36 PM.

Whether it works for reading for an hour

The bench in the shade does not work for reading for an hour right now, and what it feels like is why.

What it feels likeabout 110°F — 31°F over (at most 79°F)An hour is long enough for a few degrees to matter.

What survives out here

Things stay wet here for 12 months of the year. That, and not rainfall, is what decides what survives. Untreated softwood is the family this place punishes hardest. Family behaviour is a starting point. The exact product still decides the outcome.

Sling and mesh fabricwell suitedThe surface here peaks near 148°F. Ask the supplier: What holds the sling to the frame, and can that fixing be replaced when the fabric goes?
Tempered glasswell suitedThe surface here peaks near 148°F. Ask the supplier: What is the edge detail, and how will it be cleaned on the outside face?
Weathering steelwell suitedThe surface here peaks near 148°F. Ask the supplier: Is this a genuine weathering grade, and what does the datasheet say about wet-dry cycling and about run-off staining?
Stainless steelwell suitedThe surface here peaks near 148°F. Ask the supplier: Is it 304 or 316? Within a few miles of salt water that difference is the whole decision.
Gravel and self-binding aggregatewell suitedThe surface here peaks near 148°F. Ask the supplier: What size and shape is the aggregate, and is there an edge to keep it where it belongs?
Exterior porcelain paverwell suitedThe surface here peaks near 148°F. Ask the supplier: What is the slip classification, wet, and how is it being laid: pedestals, sand or mortar?

What belongs here

About 13.9 moles of usable light a day with about 5 hours of direct sun in high summer. That is part shade, whatever the label on the plant says. Midwinter direct sun is about 3 hours, counted on its own day, not inferred from summer.

Nothing in the reference set is a clean match here, which usually means the light or the drainage has to change first. Anything planted here sits wet for 12 months of the year, so drainage is the decision before the plant is.

What to measure before spending anything

Ranked by how far the answer actually moves across the plausible range, not by a checklist.

Who can actually see insit thereSit where you actually sit and look around. Mark the one window or path you can see a person from. Until one exists, privacy is a question we are not answering rather than one that is fine. This is not a refinement. Nothing can answer this question until somebody marks it.
What you are looking atsit thereMark the direction of the view worth keeping. No view has been marked yet, so nothing weighs what the view is worth, and a screen that blocks it looks free. This is not a refinement. Nothing can answer this question until somebody marks it.

Where this stops

  • Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
  • Wall fixings, cantilever loads and wind class are an installer's responsibility, and a badly fixed awning takes render off a wall.
  • Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.
  • This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.

Who to ask, and what to ask them

Everything this reading cannot answer goes to 6 places: a structural engineer, a drainage engineer, an electrician, your planning authority, an arborist and the manufacturer.

Inferred from the time zone America/Phoenix. A time zone identifies a country reasonably well and a county not at all, so nothing below is local to you.

A licensed professional engineer (PE), structural

Whether a wall, deck, post or fixing carries the thing you are proposing is a calculation about materials and connections. This product models sun, wind exposure and sightlines; it has never been told what the wall is made of or how the deck is framed.

Take these questions

  • Will this fixing or footing carry the load, in the wind this site actually gets?
  • What has to be opened up or exposed before that can be answered?
  • Is there a version of this that avoids a structural question altogether?

Take these with you

  • The contractor packet from this property, which has the dimensions and where each came from
  • Photographs of the wall or frame the thing would fix to
  • Anything you know about what is behind the surface

Where the register is

A drainage contractor or civil engineer

This product reads how long a surface stays wet from sun, shelter and shade. It does not know where the water goes afterwards, what the ground is made of below the top few inches, or what your drains are connected to.

Take these questions

  • Where is this water going now, and where would it go after the change?
  • Is there a connection or a soakaway involved, and is that something I am allowed to alter?
  • What would a percolation or infiltration test cost here before anybody designs anything?

Take these with you

  • The wetness reading and the months it is worst in
  • Where the downspouts land and where water stands after rain
  • Any drainage drawing that came with the property

A licensed electrician

Outdoor lighting and anything powered near water is a wiring question with a legal answer, and this product models the light rather than the circuit.

Take these questions

  • Is this circuit suitable for outdoors and for the distance involved?
  • What protection does this need, and does the work have to be certified or inspected?
  • Can the fixture be aimed or shielded the way I need without changing the wiring?

Take these with you

  • Where the fixtures would go and what they are pointed at
  • The distance from the nearest existing supply

Your city or county planning and building department

Whether you are allowed to build a thing is decided by a local rule set that varies street by street. This product has no idea which rules apply to your address, and anything it said about consent would be a guess dressed as an answer.

Take these questions

  • Does this need consent at this height, this footprint and this distance from the boundary?
  • Is there anything specific to this property — a conservation designation, a covenant, an easement, an HOA rule?
  • If it does not need consent, is there anything that would make it need one?

Take these with you

  • The dimensions and the position relative to the boundary, which the contractor packet already states
  • A site plan showing where it sits
  • The property address, which is what everything above is actually keyed to

A certified arborist

This product models a canopy as a shape that blocks light. Whether a tree is safe, whether it will survive what you are proposing, and whether you are permitted to touch it are three separate questions it cannot answer.

Take these questions

  • Is this tree safe as it stands, and does the answer change if I build near it?
  • What will this do to the root zone, and how far out does that reach?
  • Is this tree protected, and by what?

Take these with you

  • The canopy dimensions this product is using and where they came from
  • Photographs of the whole tree, including the base
  • What you are proposing to build and how close

Where the register is

  • Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.

The manufacturer or an approved installer

Wind ratings, fixing patterns and warranty conditions belong to whoever made the thing. This product can say what a change would do to the reading; it cannot say what voids the guarantee.

Take these questions

  • What is the wind rating, and in what mounting?
  • What does the warranty require of the installation and the maintenance?
  • What is the actual lead time and what does it look like in five years?

Take these with you

  • The exposure this product measured, including the windiest month
  • The fixing surface you actually have

No register is named here, because this router does not know which country holds one for you. The questions above are the same wherever you are.

The 2 lines in this document that send you here
  • Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
  • Wall fixings, cantilever loads and wind class are an installer's responsibility, and a badly fixed awning takes render off a wall.

Nothing here says what the answer will be. These are registers rather than recommendations, and a name on one is a qualification rather than an endorsement.
