Ma te whanaketanga tonu o te hangarau hau.Ka taea e te tangata te whakahaere i te taiao o roto o te whare me te hanga i te ahua o te rangi o roto.Heoi, I roto i te ahua o te koretake o te kaha o te ao, te piki haere o te pehanga o te penapena hiko me te whakaheke i te tukunga, te paheketanga o te AQI(taurangi kounga o te rangi) me te SBS(Syck Building Syndrome), ko te hanga i te hau hau e aro nui ana.

Ko te hiahia mo te hoahoa hau

1. I runga i te tono mo te rere hau hou;
2. Pūnaha hau hou me te ngenge;
3. He iti te kohi hiko, he iti te haruru me te utu mahi iti;
4. Te punaha whakahaere tika me te whakahaere.

Te whakaritenga o te whai huatanga o te hoahoanga

1. Me whakarite kia pai te whakapau o te hau poke me te hau poke o roto
2. Te whakatutuki i nga hiahia mo te noho humarie o nga tangata o roto i nga wa katoa;
3. Whakaritea te hiahia o te hau hou ina huri te maha o nga kaimahi o roto.
