Isiqondiso se-CSA vs Izinyembezi Zokusebenza Ezisizokwenzela

Ukuthi Ukusertifikathiwa ngu-CSA Kusenza Ntoni Kuzindlu Zokusebenza

Ukusertifikathiwa ngu-CSA (Canadian Standards Association) kusinika ukuthembelwa kwezinye indawo yokuphatha okuhlanganisa ukuthi izindowo zokusebenza zifanele nezinhlelo eziningi zokusebenza, ubudlelwano nesikhundla sokugcina imali yokuqhubeka kwemithambo, kanye nokugcina imali yokuqhubeka kwemithambo emhlabeni wonke weNorth America. Lokhu kukudingekile kubaphathi, abasebenzi bokubhala, nababili bokubhala abadinga ukuthembelwa kwezinhlelo zokusebenza, ukuzimiswa kwezinhlelo zokusebenza, nokuthembelwa kwezinhlelo zokusebenza ngokudlula.

Ukuvulula Isigaba se-CSA A440: Izigaba Ze-R, C, Ne-AW Sokusebenza

Isimo sika-CSA A440 sisifundisa izindlela zokusebenza zokubona ngokwesibonelo ngamathegi amathathu ahluke:

• I-Grade ye-R (Yokusebenzela eNtlo) : Izidingo ezimimumi ezinconywa kusukela kwezinhlelo zokusebenzela kwezinhlelo zokusebenza ezincane
• I-Grade ye-C (Yokusebenzela emakhaya) : Ukuphakamisa ukusebenza kwemithombo yezindawo zokusebenzela kwezindawo eziningi zokusebenzela
• I-Grade ye-AW (Yokusebenzela kwezindawo zokubuka) : Ukusebenza okuphakamile kakhulu kwezindawo ezide kanye nezinhlelo zokusebenzela kwezinhlelo ezihlukene kakhulu

Ngalokho umthetho wokugcina uqondisa ukuthi umthetho wokugcina ubhekiswe kumthetho wokugcina wokuhamba kwezinye izinto (isibonelo, ≥ 0.3 L/s·m² ngaphakathi kwe-75 Pa kuma-AW), ukufika kwezilwane (≥ 600 Pa), nokuthintana kwezilwane (≥ 4.8 kPa), ukuvumela ukuthi kwenziwe ukuchaza kahle ngokulinganisa nendlela yokusebenzela yomphakathi kanye nemithetho yezindawo zokusebenzela—kubantu isimo sokusebenzela kwezindawo zaseKanada (NBC) ya-2020.

Ukuthi ukuchazwa kwezinye izimpumelelo ngokwesibonelo sika-CSA kuthintana kanjani nokuthintana kwezinye izimpumelelo kwezinhlelo zokusebenzela

Ukugunyazwa kwe-CSA akuyona nje ukuphumelela izivivinyo zaselabhorethri kanye. Le nqubo empeleni ihilela ukuhambela okungazelelwe ezimbonini, ukuhlolwa njalo kwalokho okuphuma emgqeni wokukhiqiza, nokuhlolwa kwezinto zangempela njengokuthi amafreyimu abambelela kanjani lapho evezwa izinguquko ezinkulu zokushisa ngokuhamba kwesikhathi. Bahlola futhi ukuthi izihlungi ziyasebenza yini ezimweni zezulu ezinzima futhi bahlole izingxenye zehadiwe ukuze baqiniseke ukuthi zisebenza kahle ngemva kokusetshenziswa izikhathi eziyizinkulungwane. Zonke lezi zinyathelo zisiza ekuqedeni umehluko phakathi kokuthi ama-prototype asebenza kanjani nalokho okwenzekayo lapho imikhiqizo ifakwa ngempela ensimini. Ngokwemininingwane yomkhakha, le ndlela eqinile inciphisa izinkinga zewaranti cishe ngo-34%. Futhi ngenxa yokuthi imithetho ihlala ishintsha, izinkampani kudingeka ziqinisekise kabusha imikhiqizo yazo minyaka yonke ukuze zihlale zisesikhathini nezindinganiso zakamuva.

Izinzuzo Zokusebenza Amawindi Ezentengiselwano Aqinisekisiwe E-CSA

Ukuzuza kwe-Energy Efficiency: U-factor, SHGC, kanye ne-Air Leakage eqinisekisiwe ku-CSA A440.1

Isibonelo se-CSA A440.1 sijabula izinto ezintathu eziphambili ezihlanganisa ukuthi iminyango iphumelela kangakanani ngokuphatha kwe-energi: i-U-factor eyalwa ukuthi kuyaphuma kanjani umoya, i-SHGC noma i-Solar Heat Gain Coefficient, nokuthi kuyaphuma kanjani umoya ngeminyango. Iminyango eyiqinisekisiwe ngalesi sibonelo isebenza ngokuphakeme kwe-40% kunezinye zokuzenzakalela, okusho ukuthi izinhlayiya zokuchaza nezokuhlisa azikwazi ukusebenza ngokuphakeme kakhulu. Izirating ze-SHGC zizokhulunywa ngamaphoyinti amahle asekhaya ukuze zivule umsindo wokuzimela kumnyaka wasezinkanyezi kodwa zilungisele umsindo ophezulu xa kunezinkanyezi ezinkulu ngaphandle. Kukuthi kwezifutha kwezinyango, iziprodukthi eziqinisekisiwe ziyadlula i-0.3 litara ngosekondi ngomtre wamashumi amabili nesibhozo (0.3 L/s/m²) kusuka kwezinkanyezi ezinkulu zezinkanyezi (75 Pa), futhi akukho zinkanyezi ezinzima kubuso lwabantu emthonjeni. Konke lokhu kuhlanganiswa kungasiza ukunciphisa izibhalo zokusebenzisa i-energi ngamnyaka phakathi kwe-15% kuye kwe-30%, futhi kusiza ekubeni izindawo ziqinisekiswe ngokwemithetho yaseNingizimu Afrika yokusebenzisa i-energi.

Ukuhlanya Kwemikhono Yekhlima: Ukuvumelwa Kwemikhono Yokuphatha Kwezinkanyezi, I-Snow Load, Ne-Thermal Cycling

Ukufumana ukuthi kusetyenziswa i-CSA kusho ukuthi isithuthu singasebenza ngokupheleleyo ngokwesibonelo sokubaluleka kwezinkinga zomhlaba ngeminyaka eminingi. Izifundo zokuguqula isikhathi zihlala kusuka ku-40 degrees Celsius ku-85 degrees Celsius zibona ukuthi isithuthu sisebenza njani futhi ukuthi izilayi zisobala njani ngeminyaka. Kumaqondiso asezingeni zomhlabathi noma amastructure amaningi, ukuthintana nokuvula kuyisibonelo esibalulekile. Izifundo zibonisa ukuthi zingasebenza ngokuvula okungaphezu kwe-200 kilometers per hour. Uma kuchazwa ukuthi kunezinkomo zomkhumbi, izinto zihlala zizifundwa ngokujulile ukuze ziqinisekise ukuthi zisebenza ngendlela efanele nakuba kunezinqumo ezilingana nezinkomo eziyisithathu zomkhumbi. Lezi zifundo ezijulile zinconywa ukuthi zizivikela izinkinga eziphathelene nezinkomo, njengokuthi iglashe ikhupha, ukuvutha kwamandla okuhamba kwamanzi ngokugcwele emva kokuzimela, nokuthi isithuthu sikhiphe. Abafundi bamasipala babiza ukuthi lezi zindlela zinconywa ukuthi zizivikela izinkinga zokusebenza ngokwesibonelo sokubaluleka kwezinkinga zomhlaba ngokuphakeme kwe-25% ku-60% ngeminyaka yomkhakha.

Ukuthembekile, Ukuphatha Kwemali, Nokuphatha Kwemiphumela Ngemithombo Yezibalo

Imiphumela Yokuvikela Nokubuyisela Imithambo Yezindawo Zokusebenza Ngeminye Yezindawo Zokufinyelela Ezisizathu Sokuvikela

Izindawo zokufinyelela ezingavikeli kahle ziyenza izinkinga eziningi ngokuvikela nokuphikisana nezimithambo zokusebenza. Uma zihlukaniswa ngamandla wezulu ozungeziwe kunezingu-50 ngomzansi wamaphuzu okanye zihlukaniswa ngamandla amaningi wezimbono zokuguqula isikhathi, lezi zindawo zingabona ukuthi zihlukane futhi zibeka imithambo yezindawo zokusebenza yonke. Lokhu kungabikho kwi-standards ya-CSA A440 okufunekayo ku-Canada wonke futhi kuyasebenza emazwe amaningi ase-US. Izinkambiso zamandla wezulu kwezindawo ezingavikeli zingaba ngokwesibini kwezingu-0.3 ngomzansi wamaphuzu ngomzansi wamaphuzu, okuyisithathu sokufunekayo kwezindawo eziphikisiwe. Lokhu kuthiwa ukuthi izindawo zokusebenza azikwazi ukugcina izilwanyana ngendlela efanele futhi abantu bangabuka phakathi kwemiphumela yokuvikela. Abasayensi bokusebenza bezindawo bayaqondisa lezi zinkinga, abaprofetha bayaqhubeka ngezindlela zokuvikela ukusebenza, abahlali bayagcina izindlela zokulungisa eziningi, futhi kunezindlela zokulungisa eziningi zokuvikela ezinamandla emthambo.

Ukubhekana kwezinkampani zokusebenza, izindawo zokwakha, nokuphatha kwesibonelo ngaphandle kokuthi kwenziwe ukuthi kubhalwe ngokulinganisa kwe-CSA

Kodwa umuntu uyabize noma uyafaka amawindoyi angavumelekile, bonke abaqhubekayo ngokuphatha kwesikhathi sokufaka kubonakala ngemiphumela enkulu yokugcina nokufinyelela kwezinkinga zokugcina. Abaprofayili bafaka izinto bazolahleka izigaba zabo uma amawindoyi akakhululi kuzo izimfanekiso zokusebenza emva kokufaka. Kuma-architects, kunezinkinga ezinkulu zokuthi baphindwe ngokungafanele kwezindlela zokusebenza zokuphatha kwezindustria eziphathelene nalo. Abahlali basekhaya bazobuya bakhuleka uma abantu bafika kuzo izinkinga ngokukhula kwezinto zokufaka. Abajudje bafunda isifundo sika-CSA A440 kusikhathi sokuphatha kwezinkinga zokufaka njengokuthi kwenziwe ngokuphelele izindlela zokusebenza. Izihlombe zezinsurance ziningi zizohlukanisa ukuvumela ukuvunywa kwezinkinga zokuphatha kwezindawo zokufaka kwezinto ezingavumelekile. Ukuvumela kuka-CSA kuyabeka ubukhuleka kusukela kubani abaqhubekayo ngokuphatha kwezindawo kusukela ku-manufacturer yena. Ukwaziswa kwezinkinga zokufaka kubonisa ukuthi lokhu kungase kunciphisa ubukhuleka ngokuphelele ngamashumi ayisibhozo, futhi kuyinto enenhle kubani ofuna ukuchaza ubukhuleka wakhe ngokugcina nokufinyelela.

Ukufikelela kwezindawo zokuthengisa nokuhlinzekwa kokubhekiseka ngokulinganayo nge-CSA Certification

I-CSA certification isebenzisa njengezindlela zokufikelela kwezindawo zokuthengisa ngokuzenzakalelayo kweziqulelo zokwakha eNorth America. Iziprojekthi ezizwe kwezindawo zokulawula okuphakeme—kungakhathalisi iziprojekthi zezwe, iziprojekthi zemiphakathi, neziprojekthi zemaphakathi—zibhekisana ngokuphelele ukuthi kubhekiswe i-CSA. Uma akukho le nto, abahleli bafika kumaziko okufaka, ukuzimisa kwezilungiselelo, nokukhishwa kwezimfundo zokuthenga.

Isithi sika-CSA sifika ngaphezulu kokuqinisekisa ukuthi kufanele kwenziwe ngokwemithambo ngokuthi kusiza izibonelo ukuba zihlukane kubabili ababhekene nabo. Uma amaphuzu amathathu aqinisekisa izinto njengezindawo zokuphakama kwezinto, ukusebenza kahle kwemithambo yezimali, nokuphakama kwesikhathi sokusebenza kwezinto, lezi zinto ziyizinkinga ezingakanani uma bantu bahlala bafunda ukuthi baya kubhekana nazo kumaprojekthi yabo. Ngokwemibuzo yezikhathi ezibalulekile, ngokwesiqhelo, abadepotha abasekomisheni abaningi (ngokwesiqhelo abaningi kune-70%) bahlala bahlola isithi sokuhlanzwa uma bahlola izibuyelo. Aba-architects nababophi bakhona isithi sokuhlanzwa sika-CSA njengendlela yokukhetha izinkampani ezikunciphisa izinkinga kumaprojekthi yabo. Abadlozi bemithambo bakhona ngokuthi kusiza kubo ukuthi bahlale bafuna ubungakanani ngokwesikhathi eside emva kokuthi bafuna ukuthi kubhekane nalo ngokwesikhathi esincane kuphela. Lokho okuchazwe ngokuthi kuyisithi sokuhlanzwa sokuthembeka kusiza izibonelo ukuthi zilangele izinto zabo ngokuphakeme kunezinye, futhi zilwandlele izibonelo ezingasemthwakathini lapho zonke zihlala zibhala izinkampani ezifanayo.
