Me whai MVHR ngā hanganga hou?

I roto i te rapunga mō ngā whare e penapena ana i te hiko, kei te piki haere te hiranga o te pātai mehemea me whakamahi ngā pūnaha hau mīhini me te whakaora wera (MVHR) mō ngā whare hou. Kua puta ake te MVHR, e mōhiotia ana ko te hau whakaora wera, hei tūāpapa mō te hanganga pumau, e tuku ana i tētahi otinga atamai hei whakataurite i te kounga o te hau o roto me te tiaki hiko. Engari he aha te hiranga o tēnei hangarau mō ngā whare hou?

Tuatahi, kia mārama tātou ki te tikanga o te MVHR. I te pūtake, ka whakamahia e ngā pūnaha MVHR tētahi taputapu e kiia nei ko te recuperator hei whakawhiti i te wera mai i te hau tawhito e puta atu ana ki te hau hou e tomo mai ana. Mā tēnei recuperator ka mau tonu te wera tae atu ki te 95%, ka whakaitihia te hiahia mō te whakamahana tāpiri. I ngā whare hou, ina teitei ngā paerewa whakamahana, ā, ko te ārai hau te mea nui, ka kore e taea te whakamahi i te MVHR. Ki te kore, ka taea e te makuku, te hauhautanga, me te kounga hau ngoikore te whakararu i te hanganga me te hauora o ngā kainoho.

Tērā pea ka pātai te tangata mēnā he rawaka te hau māori. Heoi, i roto i ngā whare hou kua hiritia, kāore e whai hua te whakawhirinaki noa ki te whakatuwhera i ngā matapihi, inā koa i ngā āhuarangi makariri. Ka whakaratohia e te MVHR he hau hou tonu, me te pupuri tonu i te mahana, ā, he mea nui tēnei mō te tau katoa. Ka mahi tonu te taputapu whakaora i roto i te waeine MVHR, ahakoa ka kati tonu ngā matapihi, kia kore ai e moumou te pūngao.

Heoi anō, kei tua atu i te penapena pūngao ngā painga. Ka whai wāhi ngā pūnaha MVHR ki tētahi taiao noho hauora mā te tātari i ngā poke, ngā mate pāwera, me ngā haunga. Mō ngā whānau, ko te tikanga he iti ake ngā raruraru manawa, ā, he nui ake te whakamarie. Kāore e taea te whakanui i te tūranga o te kaiwhakaora i roto i tēnei tukanga—koinei te ngākau o te pūnaha, e āhei ai te mahi pai o te hauhautanga whakaora wera.

Tērā pea ka tautohe ngā kairīti he nui rawa te utu tīmatanga mō te tāuta i te MVHR. Heoi, ina tirohia hei haumitanga mō te wā roa, ka tere te whakakore i te utu o mua mā te penapena i ngā pire whakamahana me te karo pea i ngā whakatikatika hanganga utu nui nā te makuku. Hei tāpiri, me ngā ture hanga whare e pana ana ki ngā whāinga waro kore-kore, kāore te MVHR i te mea whiriwhiri engari he whakaritenga mō te tutuki i roto i te maha o ngā rohe.

Hei whakamutunga, kāore e kore ka whai hua ngā whare hou i ngā pūnaha MVHR. Ko te kaha o te pūwhakaora ki te whakahoki mai i te wera, me te mahi a te pūnaha ki te whakarite i te kounga pai o te hau, he mea nui tēnei mō te hanganga hou. I a mātou e whai ana ki te waihanga i ngā whare e pai ana mō te taiao me te noho, ko te hauhautanga whakaora wera he āhuatanga e kore e taea te whiriwhiri. Mō ngā kaihanga me ngā kaipupuri whare, ko te awhi i te MVHR he taahiraa ki tētahi heke mai pumau, whakamarie hoki.
