Ayini amakhodi wokwakha kanye nezindinganiso zobunjiniyela zamafasitela neminyango ye-aluminium e-US?

E-United States, amakhodi okwakha namazinga wobunjiniyela anezidingo eziqinile zokonga amandla kanye nesimo sezulu sezakhiwo, okuhlanganisa izinkomba zokusebenza ezibalulekile ezifana ne-U-value, umfutho womoya kanye nokuqina kwamanzi. Lawa mazinga asethwa yizisusa ezihlukene ezifana ne-American Society of Civil Engineers (ASCE) kanye ne-International Building Code (IBC), kanye ne-American Construction Code (ACC).
 
I-U-value, noma i-coefficient yokudlulisa ukushisa, iyipharamitha ebalulekile yokulinganisa ukusebenza okushisayo kwemvilophu yebhilidi.Lapho liphansi inani le-U, kuba ngcono ukusebenza okushisayo kwesakhiwo. Ngokwe-ASHRAE Standard 90.1, izidingo zevelu ye-U zezakhiwo zentengiso ziyahlukahluka ngendawo yesimo sezulu; isibonelo, uphahla endaweni ebandayo lungaba nenani lika-U eliphansi njengo-0.019 W/m²-K. Izakhiwo zokuhlala zinezidingo zenani le-U ezisuselwe ku-IECC (Ikhodi Yokonga Amandla Wamazwe Ngamazwe), ngokuvamile ehluka ukusuka ku-0.24 ukuya ku-0.35 W/m²-K.
 
Amazinga okuvikela ekucindezelweni komoya asekelwe ikakhulukazi ezingeni le-ASCE 7, elichaza isivinini somoya esiyisisekelo kanye nezingcindezi zomoya ezifanele ibhilidi okufanele limelane nalo. Lawa manani omfutho womoya anqunywa ngokusekelwe endaweni, ukuphakama nendawo ezungezile yesakhiwo ukuze kuqinisekiswe ukuphepha kwesakhiwo sesakhiwo ngesivinini somoya esibi kakhulu.
 
Izinga lokuqina kwamanzi ligxile ekubambeni kwamanzi ezakhiweni, ikakhulukazi ezindaweni ezijwayele ukuna kakhulu nezikhukhula. i-IBC inikeza izindlela nezimfuneko zokuhlolwa kokuqina kwamanzi ukuze kuqinisekiswe ukuthi izindawo ezinjengamajoyinti, amafasitela, izicabha nophahla ziyaklanywa futhi zakhiwe ukuze zihlangabezane nesilinganiso esishiwo sokuqina kwamanzi.
 
Ngokuqondile esakhiweni ngasinye, izidingo zokusebenza ezifana ne-U-value, ingcindezi yomoya kanye nokuqina kwamanzi kujwayele ukuhambisana nezimo zezulu zendawo yaso, ukusetshenziswa kwesakhiwo kanye nezici zaso zesakhiwo. Abadwebi bezakhiwo nonjiniyela kufanele bahambisane namakhodi okwakha endawo, basebenzise izibalo ezikhethekile nezindlela zokuhlola ukuze baqinisekise ukuthi izakhiwo ziyahlangabezana nalezi zindinganiso zokusebenza eziqinile. Ngokusetshenziswa kwalawa makhodi, izakhiwo zase-United States azikwazi nje kuphela ukumelana nezinhlekelele zemvelo, kodwa futhi zinciphisa ngempumelelo ukusetshenziswa kwamandla futhi zifinyelele ukuthuthukiswa okusimeme.
