Information

Overview

Model for the envelope of the ground floor.

Ground temperature

The ground temperature can be coupled to any desired prescriped temperature. Anyway, suitable ground temperatures depending on locations in Germany are listed as Θ'_m,e in the comprehensive table 1 in "Beiblatt 1" in the norm DIN EN 12831.

Or a ground temperature can be chosen according to a TRY region, which is listed below: if ...

TRY_Region == 1 then 282.15 K

TRY_Region == 2 then 281.55 K

TRY_Region == 3 then 281.65 K

TRY_Region == 4 then 282.65 K

TRY_Region == 5 then 281.25 K

TRY_Region == 6 then 279.95 K

TRY_Region == 7 then 281.95 K

TRY_Region == 8 then 279.95 K

TRY_Region == 9 then 281.05 K

TRY_Region == 10 then 276.15 K

TRY_Region == 11 then 279.45 K

TRY_Region == 12 then 283.35 K

TRY_Region == 13 then 281.05 K

TRY_Region == 14 then 281.05 K

TRY_Region == 15 then 279.95 K
