Toplotne značilnosti oken, vrat in polken - Izračun toplotne prehodnosti - 1. del: Splošno (ISO 10077-1:2017, popravljena različica 2020-02)

Ta dokument določa metode za izračun toplotne prehodnosti oken in vrat za pešce, sestavljenih iz steklenih in/ali prosojnih plošč, nameščenih v okvirje, s polkni ali brez njih.
Ta dokument se uporablja za:
– različne vrste zasteklitve (iz stekla ali plastike, enojna ali večkratna zasteklitev, z nanosom ali brez nanosa nizke emisivnosti in s prostori, napolnjenimi z zrakom ali drugimi plini);
– prosojne plošče v oknih ali vratih;
– različne vrste okvirjev (leseni, plastični, kovinski s termično prevleko ali brez nje, kovinski s točkastimi kovinskimi povezavami ali katera koli kombinacija materialov); in
– dodatno toplotno upornost različnih vrst zaprtih polken ali zunanjih žaluzij, kjer je to ustrezno, odvisno od njihove zračne prepustnosti.
Toplotna prehodnost strešnih oken in drugih štrlečih oken se lahko izračuna v skladu s tem dokumentom pod pogojem, da je toplotna prehodnost njihovih okvirjev določena na podlagi meritev ali številskega izračuna.
Privzete vrednosti za zasteklitev, okvirje in polkna so podane v dodatkih. Izračun ne vključuje učinkov toplotnih mostov v utorih ali spojih med okenskim ali vratnim okvirjem in ovojem stavbe.
Izračun ne vključuje:
– učinkov sončnega sevanja (glej standarde v razdelku M2-8);
– prenos toplote zaradi puščanja zraka (glej standarde v razdelku M2-6);
– izračun kondenzacije;
– prezračevanje zračnih prostorov v dvojnih ali spojenih oknih; in
– obstranski deli polkrožnih oken.
Ta dokument se ne uporablja za:
– predelne stene in druge strukturne zasteklitve (glej druge standarde v razdelku M2-5); in
– industrijska, komercialna in garažna vrata.
OPOMBA: Preglednica 1 v uvodu prikazuje relativno mesto tega dokumenta znotraj skupine standardov EPB v kontekstu modularne strukture, kot je opredeljeno v standardu ISO 52000-1.
