Ko ngā muka uku CCEWOOL te mea e whakamahia whānuitia ana i roto i ngā oumu ahumahi. Nā te whanaketanga o ngā oumu ahumahi i roto i te penapena pūngao me te tiaki taiao, kua noho te ōhanga porowhita hei huarahi nui ki te penapena pūngao me te whakaiti i ngā tukunga. Ko te ōhanga porowhita he pūnaha ōhanga e aro ana ki te whakaiti i te whakamahinga o ngā rauemi whakauru me te hanga para, te poke, me ngā tukunga waro. Ka whakamahia e ia te whakamahi anō, te tiritiri, te whakatika, te whakahou, te hanga anō me te hangarua hei hanga i tētahi pūnaha porowhita kati. Ko ngā āhuatanga matua o ngā ōhanga porowhita ko te penapena rauemi me te hangarua i ngā para.
Ko ngā oumu matomato (arā, ngā oumu e pai ana ki te taiao me te penapena hiko) e whai ana i ēnei paerewa: he iti te whakamahinga (momo penapena hiko); he iti te parahanga (momo tiaki taiao); he iti te utu; me te tino whai hua. Mō ngā oumu uku, ka taea e te arai muka uku CCEWOOL ātete-wera te whakapai ake i te whai huatanga wera. Hei whakaiti i te pakaru me te marere o ngā muka uku, ka whakamahia ngā rauemi paninga maha-mahi (pēnei i ngā paninga infrared tawhiti) hei tiaki i ngā muka uku, e kore e whakapai ake i te ātete pakaru o ngā muka engari ka whakanui ake hoki i te pai o te whakawhiti wera i roto i te oumu, e penapena ana i te hiko, me te whakaiti i te whakamahinga. I taua wā, ko te iti o te kawe wera o ngā muka uku ka hua ake te whakapai ake i te tiaki wera o ngā oumu, te whakaiti i te ngaronga wera, me te whakapai ake i te taiao tahu.
I roto i ngā tau rua tekau kua pahure ake nei, kua rangahau te muka uku CCEWOOL i ngā otinga penapena pūngao mō te muka uku i roto i ngā oumu ahumahi; kua whakaratohia e ia ngā otinga penapena pūngao tino pai mō te muka uku mō ngā oumu i roto i te maitai, te matū hinu, te whakarewa me ētahi atu mara ahumahi; kua whai wāhi atu ki ngā kaupapa whakawhiti o neke atu i te 300 oumu ahumahi nui puta noa i te ao mai i ngā oumu taumaha ki ngā oumu taiao-pai, penapena pūngao, me ngā oumu māmā, e hanga ana i te muka uku CCEWOOL hei waitohu matua mō te whakarato otinga penapena pūngao mō ngā oumu ahumahi.
