Metodologija

Šapice ne pokušava da pretvori procenu u sertifikat. Svaki model razdvaja ono što je preuzeto iz pouzdanog izvora, ono što proizilazi iz geometrije, ono što računamo i ono što još ostaje pretpostavka.

SOURCE

Vrednost ili pravilo potiče iz spoljnog izvora koji je evidentiran u bazi izvora.

GEOMETRY

Vrednost se izvodi direktno iz kanonske geometrije modela, bez ručnog dupliranja.

CALCULATION

Vrednost je rezultat determinističkog proračuna nad poznatim ulazima.

ASSUMPTION

Projektantska pretpostavka je eksplicitno označena i ne predstavlja potvrđenu činjenicu.

Termički proračun

Trenutni engine računa približan steady-state prolaz toplote kroz zidove, pod i krov. Metod v1.2.0 koristi ISO 6946 orijentacione površinske otpore: Rsi 0,13 m²K/W za zidove, 0,10 za krov pri toku toplote naviše i 0,17 za pod pri toku naniže, uz Rse 0,04 m²K/W. Model još ne tvrdi pouzdanu infiltraciju kroz ulaz, metaboličku toplotu životinje, vetar, 2D termičke mostove rama ili punu higrotermalnu dinamiku. Zato prikaz nije temperaturna garancija.

Ventilacija

V1 ne tvrdi univerzalnu potrebnu površinu ventilacionog otvora. Compiler rezerviše high-rear PROVISION zone koje ne seku provisional framing, ali stvarni cutout i net free area zavise od konkretnog podesivog ventilacionog umetka. Terenska provera mora obuhvatiti kondenzaciju, vlagu i lokalnu promaju. Termički engine ne računa ventilacioni protok kroz te buduće otvore.

Grejanje

Aplikacija ne projektuje improvizovane električne grejače. Grejani modeli definišu prostor i ograničenja za kompatibilan namenski pet-heating proizvod, dok su njegove deklaracije i uputstvo proizvođača autoritativni za ugradnju.

Status validacije

  1. DATA_VALIDATED
  2. GEOMETRY_VALIDATED
  3. ENGINEERING_REVIEWED
  4. PROTOTYPE_BUILT
  5. FIELD_TESTED

Status se podiže samo kada je prethodni nivo stvarno završen. Softverski testovi nikada se ne predstavljaju kao fizičko testiranje kućice.
