Laka o ka wela owili z type kila lau puʻu ua symmetrically puunaue ma na aoao elua o ka neutral axis, a me ka punaewele mea mau, i nui hoʻomaikaʻi i ka pauku modulus a me ka bending stiffness, a e hōʻoia i ka mechanical ano o ka pauku hiki ke hoʻokō pono.

1) ʻOi aku ka lōʻihi o nā paʻa paʻa: ʻO kēia ka mea e hiki ai i nā ʻāpana ke hoʻokele a huki ʻia i nā manawa he nui ma mua o ka pau ʻana o nā interlocks.

2) ʻOi aku ka maikaʻi no ka hoʻokele hoʻokele paʻakikī: ʻOi aku ka mānoanoa a ʻoi aku ka mānoanoa o nā mea pili i nā puʻu pepa i ʻōwili ʻia.Hāʻawi kēia i nā puʻu pepa i ka ikaika nui e hoʻokuʻu ʻia i loko o nā kūlana lepo paʻakikī

3) ʻOi aku ke kiʻekiʻe o ke kila hana hou ʻia: ʻO nā koi LEED i kekahi manawa e kuhikuhi i ka hoʻohana ʻana i nā mea hana hou.Loaʻa i ka 100% mea kila i hana hou ʻia nā puʻu pepa wela, ʻoiai ʻo nā puʻu pepa i hana ʻia i ke anuanu ma kahi o 80% mau mea hana hou.

4) ʻoi aku ka paʻa o ka wai: ʻoi aku ka maikaʻi o nā puʻu pepa wela i nā hoʻāʻo seepage, ma muli o ka nui o nā paʻa paʻa.
