Hei wāhanga matua o ngā pūnaha tiaki uira, ka pā tika te kōwhiringa tika o te tokotoko uira ki te haumaru o te whare. Me whakataurite te whakataunga i ngā whakatakotoranga hangarau, ngā āhuatanga taiao, me te tutuki i ngā ture.
1. Kōwhiringa Momo mā te Mahi
Ngā Rākau Franklin: He pai mō ngā whare noho me te radius tiaki 30m. Me hanga he maitai piauau me ngā whatunga whenua motuhake.
Ngā Tokotoko ESE (Tukunga Rerema Moata): Whakawhānuihia te kapinga ki te 100m mā te whakamahi i te whakaoho hiko, he mea tino pai mō ngā whare nui pēnei i ngā pokapū raraunga. Manatokohia ngā tiwhikete CE/UL.
Ngā Rākau Irahiko (He Herea): Kua rāhuitia i roto i ngā hanganga hou o Haina i raro i te GB 50057 mai i te tau 2005 nā te mea he tūponotanga irahiko.
02. Te Hangarau Taiao-Motuhake
Tātaitanga Teitei: Whakamahia te tikanga porowhita hurihuri $ h = \sqrt{2rH – H^2}$ (h: teitei o te tokotoko, r: pūtoro porowhita, H: teitei o te hanganga)
Ātete Waikura: Whakamahia te maitai kore waikura 316L (ātete ki te rehu tote >720hr) ki ngā rohe takutai; te koranu parahi-titanium (pH 2-12 te manawanui) mō ngā rohe matū
Te Matotoru o te Uira: I ngā rohe mahi nui (>90 ngā rā āwhatiwha ia tau), whakanuia ake ngā hiko whakawhenua mā te 25%.
03. Tāutanga e Tutuki ana i ngā Waehere
Wāhanga Hoahoa: Kia mau tonu te ātete whenua <10Ω (<4Ω mō ngā whare motuhake), whakatinanahia ngā pūnaha whenua TN-S/TT
Hanganga: Whakamahia te whakarewa wera mō ngā pito hau/ngā ara iahiko me te taupatupatu neke atu i te 12cm
Tirotiro: Whakamātauria te aukati i te nekehanga mā roto i ngā mita iahiko nekehanga CDM-10; manatokohia te hononga ki ngā whakaahua infrared
Tohutohu Tiaki: Aroturukihia te ātete o te whenua me ngā mita moroiti-ohm ia rua tau, whakakapia ngā paninga hiko whakararo ia 5 tau kia mōhio ai koe e tutuki ana ngā whakaritenga o te IEC 62305 puta noa i te huringa ora tiakitanga.
