Takulandilani ku Thomas Insights - timafalitsa nkhani zaposachedwa komanso kusanthula tsiku lililonse kuti owerenga athu azidziwa zomwe zikuchitika mumakampani. Lowani apa kuti mutumize mitu yatsiku mwachindunji kubokosi lanu.
Imodzi mwa njira zosavuta komanso zosavutikira zopezera kukhazikika kwa mafakitale kungakhale kugwiritsa ntchito madenga ozizira.
Kupanga denga "kuzizira" kumakhala kosavuta monga kujambula pa pepala loyera kuti liwonetse kuwala ndi kutentha m'malo mozilowetsa m'nyumba. Posintha kapena kuyikanso denga, kugwiritsa ntchito zokutira zowunikira bwino m'malo mwa zida zofolera zachikhalidwe kumatha kuchepetsa mtengo wowongolera mpweya ndikuchepetsa kwambiri kugwiritsa ntchito mphamvu.
Ngati mutangoyamba kumene ndikumanga nyumba kuyambira pachiyambi, kukhazikitsa denga lozizira ndi sitepe yoyamba yabwino; nthawi zambiri, palibe ndalama zowonjezera poyerekeza ndi madenga achikhalidwe.
"Denga lozizira" ndi imodzi mwa njira zofulumira komanso zotsika mtengo kwambiri zochepetsera mpweya wa carbon padziko lonse ndikuyamba kuyesetsa kuthetsa kusintha kwa nyengo," anatero Steven Zhu, yemwe kale anali Mlembi wa Zamagetsi ku United States.
Kukhala ndi denga lozizira sikumangowonjezera kukhazikika, komanso kumachepetsa kudzikundikira kwa katundu wozizira komanso "chilumba cha kutentha kwa m'tawuni". Pamenepa, mzindawu ndi wotentha kwambiri kuposa madera akumidzi ozungulira. Nyumba zina zikuyang'ananso madenga obiriwira kuti madera akumidzi azikhala okhazikika.
Dongosolo la denga limakhala ndi zigawo zingapo, koma kunja kwa dzuwa kumapangitsa kuti denga likhale "lozizira". Malinga ndi malangizo a Dipatimenti ya Zamagetsi posankha madenga ozizira, madenga amdima amatenga 90% kapena kuposerapo mphamvu ya dzuwa ndipo amatha kufika kutentha pamwamba pa 150 ° F (66 ° C) nthawi ya dzuwa. Denga lowala limatenga mphamvu zosakwana 50% za mphamvu ya dzuwa.
Utoto wozizira wapadenga ndi wofanana ndi utoto wandiweyani kwambiri ndipo ndi njira yabwino kwambiri yopulumutsira mphamvu; siziyenera ngakhale kukhala zoyera. Mitundu yozizira imawonetsa kuwala kwa dzuwa (40%) kuposa mitundu yakuda yofananira (20%), koma yotsika kuposa yowala (80%). Zovala zapadenga zozizira zimathanso kukana kuwala kwa ultraviolet, mankhwala ndi madzi, ndipo pamapeto pake zimakulitsa moyo wa denga.
Kwa madenga otsetsereka, mutha kugwiritsa ntchito zomangira zamakina, zomatira, kapena zopukutira monga miyala kapena zopindika kuti mugwiritse ntchito mapanelo amtundu umodzi padenga. Denga lozizira lophatikizana limatha kumangidwa poyika miyala mu phula wosanjikiza madzi, kapena kugwiritsa ntchito mapanelo amchere okhala ndi tinthu tating'ono ta mchere tonyezimira kapena zokutira zopaka fakitale (mwachitsanzo, ma membrane osinthidwa a asphalt).
Njira ina yabwino yozizirira padenga ndikupopera thovu la polyurethane. Mankhwala awiri amadzimadziwa amasakanikirana ndikukula kuti apange chinthu cholimba chofanana ndi styrofoam. Imamatira padenga ndipo imakutidwa ndi chophimba chozizira choteteza.
Njira yothetsera chilengedwe pa madenga otsetsereka ndi ma shingles ozizira. Mitundu yambiri ya phula, matabwa, polima kapena matailosi achitsulo amatha kuphimbidwa panthawi yopanga fakitale kuti apereke mawonekedwe apamwamba. Denga la dongo, slate, kapena matailosi a konkriti amatha kuwonetsa mwachilengedwe, kapena amatha kuthandizidwa kuti apereke chitetezo chowonjezera. Chitsulo chosapentidwa ndi chowonetsera bwino cha dzuwa, koma mpweya wake wotentha ndi wosauka kwambiri, choncho uyenera kupakidwa utoto kapena wokutidwa ndi zokutira zoziziritsa kukhosi kuti ukwaniritse denga lozizira.
Ma solar solar ndi njira yobiriwira yobiriwira, koma nthawi zambiri samapereka chitetezo chokwanira padenga ndipo sangaganizidwe ngati yankho lozizira padenga. Madenga ambiri sali oyenera kuyika ma solar panels. Kumanga ntchito photovoltaics (ma solar panels kwa madenga) akhoza kukhala yankho, koma izi zikadali pansi pa kufufuza kwina.
Osewera akulu omwe akugunda msika wozizira wapadziko lonse lapansi ndi Owens Corning, CertainTeed Corporation, GAF Materials Corporation, TAMKO Building Products Inc., IKO Industries Ltd., ATAS International Inc., Henry Company, PABCO Building Products, LLC., Malarkey Roofing Companies ngati Polyglass SpA ndi Polyglass SpA amaphunzira zatsopano zamadenga ozizira, ndikugwiritsa ntchito matekinoloje apamwamba kwambiri monga ma drones kuti azindikire madera omwe ali ndi vuto ndikuzindikira zoopsa zachitetezo; amawonetsa makasitomala awo njira zabwino zobiriwira.
Ndi kuwonjezeka kwakukulu kwa chiwongoladzanja ndi kufunikira kwa kukhazikika, teknoloji yapadenga yozizira imasinthidwa nthawi zonse ndikupangidwa.
