Muri Reta zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zunzubumwe zamerika, amategeko agenga inyubako hamwe n’ibipimo ngenderwaho byubwubatsi bifite ibyangombwa bisabwa kugirango ingufu zikorwe neza n’ikirere cy’inyubako, harimo ibipimo ngenderwaho byingenzi nka U-agaciro, umuvuduko w’umuyaga hamwe n’amazi akomeye. Ibipimo ngenderwaho byashyizweho nubushake butandukanye nka societe yabanyamerika yububatsi (ASCE) hamwe n’amategeko mpuzamahanga yubaka (IBC), hamwe n’amategeko agenga imyubakire y'Abanyamerika (ACC).
U-gaciro, cyangwa coefficient de transfert yubushyuhe, nikintu cyingenzi mugupima imikorere yubushyuhe bwibahasha yinyubako. Hasi U-gaciro, niko imikorere yinyubako ikora neza. Ukurikije ASHRAE Standard 90.1, U-agaciro gasabwa ku nyubako zubucuruzi ziratandukanye bitewe nikirere; kurugero, ibisenge mubihe bikonje birashobora kugira U-agaciro kari munsi ya 0.019 W / m²-K. Inyubako zo guturamo zifite U-agaciro gasabwa hashingiwe kuri IECC (Kode mpuzamahanga yo kubungabunga ingufu), ubusanzwe itandukana kuva 0.24 kugeza 0.35 W / m²-K.
Ibipimo byo kwirinda umuvuduko w’umuyaga bishingiye ahanini ku gipimo cya ASCE 7, gisobanura umuvuduko w’ibanze w’umuyaga n’umuyaga uhuye n’inyubako igomba kwihanganira. Indangagaciro z'umuyaga zigenwa hashingiwe aho biherereye, uburebure n'ibidukikije bikikije inyubako kugirango umutekano wubatswe winyubako ku muvuduko ukabije w’umuyaga.
Igipimo cy’amazi cyibanze ku gukomera kw’inyubako, cyane cyane ahantu hashobora kugwa imvura nyinshi n’umwuzure. IBC itanga uburyo n'ibisabwa mu gupima amazi kugira ngo harebwe niba ahantu nk'ingingo, amadirishya, inzugi n'ibisenge byateguwe kandi byubatswe kugira ngo byuzuze igipimo cy’amazi.
Umwihariko kuri buri nyubako, ibisabwa nkibikorwa nka U-agaciro, umuvuduko wumuyaga hamwe nuburemere bwamazi bamenyereye guhuza nikirere cyikirere giherereye, imikoreshereze yinyubako nibiranga imiterere. Abubatsi naba injeniyeri bagomba kubahiriza amategeko yimyubakire yaho, bagakoresha imibare idasanzwe nuburyo bwo gupima kugirango inyubako zuzuze ibipimo ngenderwaho bikomeye. Binyuze mu gushyira mu bikorwa aya mahame, inyubako zo muri Amerika ntizishobora gusa guhangana n’ibiza byibasiwe n’ibiza, ariko kandi zigabanya neza gukoresha ingufu no kugera ku majyambere arambye.
