The hedge that browns on one side every winter

Before you buy a pergola, move the table.

Every change below is put into the plan and the whole model is run again. That is why a pergola's winter cost shows up here without anybody having written it down, and why the cheapest thing that works is allowed to win.

Where it stands now

Something left out here

The seaward face works for leaving things out across the year.

  • Ultraviolet dose is0.3 MJ/m2/day over— 1.4 MJ/m2/day against at most 1.1 MJ/m2/day

    Ultraviolet dose is cumulative and does not care whether anyone is sitting there.

  • How long it stays wet is1.6h over— 13.6h against at most 12h

    Repeated wetting with slow drying is what actually destroys outdoor things, far more than rainfall totals.

Confidence low (43%). Treat this as a starting hypothesis, not an answer.

What this answer was built from
  • Use
    Something left out here
  • Place
    The seaward face
  • Weather
    Coastal Mediterranean, dry summers, salt air (scenario shape) (from a published source)
  • Method
    Twelve representative days across the year, read at the month that punishes hardest
    • Something left out here is read across a whole day or year rather than at one hour, so single changes are compared on the questions pages instead. Go there.
