I roto i te whakahaeretanga o ngā wheketere hou, ka tūtaki tonu ngā kaiwhakahaere ki ētahi āhuatanga uaua me te mamae e pā ana ki a rātou: te pikinga tonu o ngā pire hiko, ngā amuamu a ngā kaimahi i roto i ngā taiao uaua, te kino o te kounga whakaputa nā te piki me te heke o te taiao, me te piki haere o ngā whāinga tiaki hiko me te whakaiti i ngā tukunga. Ehara ēnei i te mea iti noa iho engari he wero matua e pā tika ana ki te whakataetae matua o ngā umanga. He mea whakaharikoa te kite i tētahi otinga ngāwari engari he tino mohio kei te iri i runga ake i te whare wheketere – arā, ko te Pā nui tere-iti teitei (Pā HVLSEhara i te mea he "hau e rere noa ana", engari he taputapu kaha hei aro turuki i ngā mamae o ēnei wheketere.

Ngā Wero1: He nui te whakapaunga pūngao, he nui ngā utu mō te whakamatao i te raumati, me te whakamahana i te takurua.

Ngā herenga o ngā otinga tuku iho: I roto i ngā wāhi wheketere nunui, he tino nui te utu mō te whakamahi i ngā hauhautanga tuku iho hei whakamatao. I te takurua, nā te pikinga ake o te hau wera, ka puta he wāhi pāmahana teitei i raro i ngā tuanui, engari ka noho makariri tonu ngā wāhi whenua e mahi ana te tangata.

Otinga HVLS

Mā te hurihuri puhoi o ōna mata nunui, ka panaia e te pā hau HVLS te nui o te hau ki raro, ka hangaia he rere hau whai hua. I te takurua, ka panaia mārire te hau wera kua kohia i runga i te tuanui ki te whenua, ka whakakorea rawatia te wehewehenga pāmahana. Ka taea e tēnei te whakatutuki i te tohatoha wera ōrite, ā, ka penapena i te 20-30% o ngā utu whakamahana. I te raumati, ka puta he pānga whakamatao mimiti i runga i te kiri o ngā kaimahi nā te rere tonu o te hau, ka heke te pāmahana, ka mātao ake te tangata i te 5 ki te 8 nekehanga Celsius, ā, ka whakaitihia, ka whakakapia rānei te whakamahinga o ētahi hauhautanga e pau ana te kaha. Ko tōna whakamahinga hiko kotahi he rite noa ki te whakamahinga o te rama mura o te whare, engari ka taea e ia te kapi i te rohe o ngā mano mita pūrua, me te hokinga mai o te haumitanga tino nui.

Ngā Wero2: Te kounga hua kore pumau me te kino ki ngā rauemi tairongo pāmahana me te makuku

Ngā herenga o ngā otinga tuku iho: Mō te maha o ngā ahumahi, pērā i te hanga tino tika, te tukatuka kai, te putunga rongoā, te tukatuka kakahu me te rakau, ko ngā rerekētanga o te pāmahana me te haumākū o te taiao ngā "kaipatu ngaro" o te kounga hua. Ka taea e te rakau te huri i te āhua nā te kore taurite o te haumākū, ka tere ake te pirau o te kai, ā, ka makuku pea ngā wāhanga hiko tino tika. Ka taea e ēnei katoa te arahi ki ngā mate nui me te maumau moni.

Otinga HVLS

Ko te mahi matua o te pā hau HVLS ko te whakakore i te hau. Mā te whakaoho tonu me te ata whakaoho, ka noho rite tonu te pāmahana me te haumākū o te whare wheketere. Mā tēnei ka noho pumau, ka taea hoki te whakarite i tētahi taiao rokiroki me te whakaputa mō ngā rauemi me ngā hua e pāngia ana e te pāmahana me te haumākū, ka whakaiti i te kino o te hua, te waikura, te whakarerekētanga rānei i puta mai i ngā huringa taiao, ā, ka tiakina tika hoki ngā rawa matua me ngā hua o ngā umanga.

Ngā Wero3: He taiao whakaputa kino, ka pāngia ngā kaimahi e te ahotea wera, te iti o te whai huatanga me te nui o ngā mōrearea hauora

Ngā herenga o ngā otinga tuku iho: Ko ngā awheawhe he nui te pāmahana, he kikī, he hau pūmau te hoariri matua o te whai hua me te haumaru. He ngāwari ngā kaimahi ki te ngenge me te kore aro, ehara i te mea ka heke te hua engari ka nui ake te tūponotanga ka pāngia rātou e ngā raruraru hauora mahi pēnei i te whiu wera. I taua wā anō, ko te tikanga o te hau pūmau he uaua ki te marara te puehu, te paoa me ngā matū waro pūngao (VOC), ka waiho hei mōrearea mō te wā roa ki te hauora manawa o ngā kaimahi.

Otinga HVLS

Te hau whānui, maeneene hoki i hangaia eNgā pā HVLSKa taea te whakaiti i te urupare a ngā kaimahi ki te ahotea wera, me te pupuri i te pāmahana e kitea ana i roto i te awhe whakamarie. Ka mātao ake te ahua o ngā kaimahi, ka aro nui ake, ka iti ake te tere hapa, ā, ka pai ake te mahi me te wairua. Ko te mea nui ake, ka taea e te rere tonu o te hau te wawahi i te kohikohinga o te puehu me te paoa, ka pana atu ki te pūnaha whakaputa hau, ka whakawaiwai rānei ki te kukū haumaru, ka whakapai ake i te kounga o te hau o roto, ka waihanga i tētahi taiao mahi hauora ake, haumaru ake hoki mō ngā kaimahi.

He maha ngā wero o ngā wheketere he pūnaha, ā, he otinga atamai pūnaha tika tā ngā pā hau HVLS. E neke atu ana i te ariā o ngā taputapu whakapūngao tuku iho, ā, kua waiho hei tūāpapa whakauru e whakakotahi ana i te tiaki pūngao me te whakaiti i te whakapaunga, te whakapai ake i te taiao, te whakapūmau kounga, me te manaaki kaimahi. Ehara i te mea ko te hoko taputapu anake te haumi ki ngā pā hau HVLS; he haumi rautaki ki te whai huatanga o te whakahaere a te hinonga, te hauora o ngā kaimahi, me te heke mai pumau. Ka hurihia te "wāhi mamae utu" i mua hei "mīhini uara" e akiaki ana i te hinonga ki mua.
