三，Te Kōwhiri i tētahi Arotahi mō roto, mō waho rānei: He aha te Rerekētanga?
I te wā e whiriwhiri ana i tētahi karu tirotiro mō roto, mō waho rānei, he iti noa ngā rerekētanga matua hei whakaaroaro nā runga i ngā āhuatanga motuhake o ēnei taiao. Anei ngā mea me mōhio koe:
Ngā Āhuatanga Rama:He rerekē ngā āhuatanga mārama o ngā taiao o waho, tae atu ki te hihi kanapa o te rā, ngā atarangi, me ngā āhuatanga mārama iti i te pō. Engari, ko ngā taiao o roto, he nui ake te whakahaere i ngā āhuatanga mārama me te māramatanga ōrite. Nō reira, me whai whakaaro te kōwhiringa arotahi ki ngā wero mārama motuhake o ia taiao.
Waho:Kōwhiria he karu arotahi he whānui te whakatuwheratanga (he iti te tau-f) hei kohikohi i te māramatanga i ngā āhuatanga mārama iti. Mā tēnei ka pai ake te tirohanga me te kounga o te ahua i te ahiahi, i te atatu, i te pō rānei. Hei tāpiri, ka taea e ngā karu arotahi he pai te whānuitanga hihiri te whakahaere i te rerekētanga i waenga i te rā kanapa me ngā wāhi atarangi.
Ā-roto: Nā te mea he rite tonu te mārama o ngā taiao ā-roto, he rawaka pea ngā karāhe he paku tuwhera te rahi. Ka taea tonu e te karāhe he paku teitei ake te tau-f te whakaputa i te kounga pai o te ahua i roto i ngā tautuhinga ā-roto, me te kore e hiahiatia he whānui te tuwhera.
Te Mara Tirohanga:Ka rerekē pea te whānuitanga tirohanga e hiahiatia ana i runga i te rahi me te tahora o te wāhi tirotiro.
Waho: Ko ngā wāhi o waho e hiahia ana kia whānui ake te tirohanga hei aroturuki i ngā wāhi nunui. Ko ngā karāhe whānui te whakamahinga hei hopu i tētahi tirohanga whānui ake, inā koa mō ngā wāhi tuwhera pērā i ngā papa waka, i ngā wāhi o waho rānei o te whare.
Ā-roto: Ka rerekē pea te whānuitanga o te tirohanga mō te tirotiro ā-roto i runga i te wāhi motuhake e aroturukitia ana. I ētahi wā, he pai pea te whakamahi i te karu tirohanga whānui hei uhi i tētahi rūma nui ake, i tētahi ara rānei. Heoi, i ngā wāhi kuiti, i ngā wāhi rānei e tika ana te aroturuki taipitopito, he pai ake pea te whakamahi i tētahi karu tirohanga whaiti ake, i te kaha rānei ki te whakarite i te roa arotahi (kanu arotahi rerekē).
Ātete ki te HuarereMe hanga ngā kāmera tirotiro me ngā karāhe tirotiro o waho kia tū atu ki ngā āhuatanga kino o te rangi, pērā i te ua, te hukarere, te puehu, te pāmahana tino kino rānei. He mea nui kia whiriwhiria ngā karāhe tirotiro i hangaia mō te whakamahinga o waho, ā, he maha ngā wā ka tae mai me ngā āhuatanga ātete ki te huarere pērā i ngā ārai hiri hei tiaki i te makuku me te paru.
Te Ātete ki te Kaipahua:I ngā taiao o waho, he nui ake te mōrearea o te mahi kino, te whakarerekē rānei. Whakaarohia ngā karaihe he āhuatanga tiaki pērā i ngā anga ātete-pānga, ngā porowhita rānei hei ārai i te kino, me te whakarite kia kore e whakararuraruhia te mahi a te kāmera me te kounga o te ahua.
Hototahitanga IR:Mena kei roto i tō pūnaha tirotiro he whakamārama infrared (IR) mō te tirohanga pō, me whakarite kia hototahi te arotahi ki te mārama IR. Tērā pea he tātari tapahi IR kei ētahi arotahi hei whakarei ake i te kounga o te ahua i te awatea, me te tuku hoki i te whakamārama IR whai hua i te pō.
