The table is open for working outside 9:00 AM to 5:00 PM, March to November. It opens at different hours December to February.

  • December to February: open 12:00 PM to 4:00 PM. What it feels like is what closes it.
  • March to November: open 9:00 AM to 5:00 PM. What it feels like is what closes it.

What it feels like is the commonest thing to end the day for working outside here.

September 14 · The table

The evidence behind this whole day is thin, so nothing on the strip is marked out as worse than the rest. The shape of the day is still the model’s best reading; the confidence in it is low, and it stays low until something it needs is measured.

The table is open for working outside 12:00 AM to 11:30 PM.

About 23.5 hours in September.

Work outside

The table works for working outside at this hour.

  • What it feels like is inside what this use needs: 63.1°F against 60.8°F to 80.6°F.
  • Glare is inside what this use needs: 0 / 100 against at most 14.
  • Direct sun is inside what this use needs: 0 / 100 against at most 55.

What this answer was built from
  • Use
    Work outside
  • Place
    The table
  • Weather
    Hot and humid, long cooling season (scenario shape), scenario (from a published source)
  • Method
    Traced geometry and radiation at this hour, measured against what this use needs
  • How well this place is described

    Mapped
    1. Quick
    2. Mapped
    3. Annotated
    4. Measured

    Shade, sky view and daily light are computed from real geometry rather than assumed. This is the rung at which the product starts telling you things you did not already know.

    It cannot answer who can see in, and it cannot tell you whether the heights it is using are the real ones.

    To reach Annotated

    • Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
    • Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
    • Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.

    What that buys: The privacy question, and a check on the geometry. Most inferred heights are wrong by enough to matter, and a photograph settles it in a minute.

    Everything that was checked
    • Quick A place on the earth: New York (demonstration), with a time zone, which is what makes an hour an hour.
    • Quick Somewhere to read: 1 spot marked. A reading is a height at a place, and moving it moves the answer.
    • Mapped The things in the way: 5 objects drawn. The house counts, and so does the neighbour's.
    • Mapped What is underfoot: 1 of 1 readings sit on a mapped surface.
    • Mapped Where the property ends: Drawn, so the product can tell you when the cheapest fix stands on someone else's land.
    • Annotated Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
    • Annotated Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
    • Annotated Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.
    • Measured Heights off a tape: 4 of 5 objects are measured. The remaining 1 are this product's own inference, so no figure here is a survey figure yet.
    • Measured Something checked against the day: Nothing has been checked against a real afternoon. The model is unopposed, which is not the same as being right.

    What to measure next

    Ranked by how far the answer moves, not by a checklist
    1. 1Who can actually see inSit in the chair

      Sit 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.

      Currently assuming: nobody is overlooking this. Tested across one confirmed observer changes the whole privacy answer.

    2. 2What you are looking atSit in the chair

      Mark the direction of the view worth keeping. Without it, every screening recommendation is optimising against nothing.

      This is not a refinement. Nothing can answer this question until somebody marks it.

      Currently assuming: no view is being protected. Tested across one corridor changes what screening is worth doing.

    How this was worked out

  • Privacy exposure

    Unanswered

    No observer has been placed yet. Privacy is a question about who can see in from where, and until one is marked there is nothing to answer.

    Wind

    South screen is taking about 60% of the wind off this spot.

    What is doing it

    • South screen

    • Lanai roof

      0.5 mph
    How this was worked out

  • At seat height
    1.9 mph before shelter
  • Shelter

  • View

    Unanswered

    No view worth keeping has been marked, so there is nothing to weigh a screen against yet.

    Surface heat

    77.4°F

    Surface temperature · 20 on the reporting scale

    The surface is running about 77°F.
