Ka whakahaerehia e tēnei aromatawai he tātaritanga mō ngā painga penapena hiko i puta i muri i te tāutanga Koti ārai Werai runga i ngā takirere me ngā taputapu. I mua i te whakahoutanga, i tukuna e ngā wāhanga pāmahana teitei o ngā takirere me ngā taputapu he nui te kaha wera mā te irahiko me te whakawhiti hiko, ā, ka hua ake te koretake o te whakapaunga hiko. I taua wā, i piki ake te pāmahana o te rohe e karapoti ana, ā, i whakararu i te whakamarie o te mahi me te pumau o te mahi taputapu. Ka taea e te paparanga whakamarumaru kua whakauruhia te whakaiti i ngā huringa pāmahana o ngā taputapu, te whakaiti i te kino o te ahotea wera, me te whakaiti i te tere rahunga me ngā utu tiaki. Mai i te tirohanga o te hokinga mai o te haumi, ka taea te whakahoki mai i te whakaurunga whakahoutanga i roto i te wā poto mā te penapena hiko. Ka tukuna e ia ngā painga ōh(huán)anga me te taiao, e whakarato ana i te tautoko kaha mō te whanaketanga matomato me te iti-waro o ngā umanga. E whakaatu ana ngā hua whakamātautau mara: ko te pāmahana o roto o te taiao he tata ki te 45–60℃, ā, ko te pāmahana mata o ngā taputapu takirere whakahaere kei waenga i te 110℃ ki te 190℃. Ko te ngaronga wera i ngā wā katoa kua nui ake i te uara mōrahi o te wera e whakaaetia ana kua tohua i roto i te paerewa ā-motu GB/T 8174-2008.

Mō te kaupapa o te whakarato i ngā koti whakamahana ka taea te tango i ngā puranga taputapu katoa i roto i te awheawhe R2/R3/perehi hinu/whakapaipai/pōro, kua oti i tā mātou kamupene te whakatau tata tahua kaupapa i runga i ngā tawhā whakatakotoranga o te matapae taputapu, ngā tohu mahi o Rauemi ārais (te kawe wera λ ≤ 0.030W/(m·℃)) me ngā whakaritenga mō te whakaritenga ā-pūtau. Ko te utu whānui mō tēnei puranga o ngā koti whakamahana koia tēnei: ??[R2: USD 7160.04], [R3: USD 10856.00], [pēhi hinu: USD 37391.73], [whakapaipai: USD 26006.76], [awheawhe kohua: USD 3009.55]. Kei roto i tēnei utu te tuku rauemi, te tukatuka ritenga, te urutau i te papaanga me te tono. Mai i te tirohanga o te hokinga mai o te haumitanga kaupapa, e whakawhirinaki ana ki te tere whakaiti i te whakamahinga pūngao whakamarara wera ā-tau (≥ 85%) i tutukihia e tēnei kaupapa whakamahana, e kiia ana ko te wā whakahoki hihiri he 8 marama, ka taea te kapi i te haumitanga tuatahi me te whakaputa hua pumau mai i te arotautanga utu pūngao.
