Ndi zovuta zakusintha kwanyengo padziko lonse lapansi komanso kukula kwa anthu, kugwiritsa ntchitowowonjezera kutenthaukadaulo muulimi wakhala wofunikira kwambiri. Kukula ndi kugwiritsa ntchito zatsopanowowonjezera kutenthazipangizo osati bwinowowonjezera kutenthakupanga bwino komanso kupereka njira zatsopano zaulimi wokhazikika. Nazi zina mwazambiri zatsopano zingapowowonjezera kutenthazida zomwe ndasonkhanitsa:
1.Transparent Radiative Cooling Film (T-RC):
Transparent Radiative Cooling Film (T-RC) ndi mtundu watsopano wawowonjezera kutenthakuphimba zinthu zomwe zingachepetse kupsinjika kwa kutentha mkati mwa wowonjezera kutentha popanda kukhudza photosynthesis ya zomera. Kanema wa T-RC amakhala ndi mpweya wambiri pazenera lamumlengalenga, kufalikira kwakukulu mu bandi yogwira ntchito ya photosynthetically yogwira ntchito, komanso kuwunikira kwambiri mu bandi yapafupi ndi infrared radiation. Poyerekeza ndi mafilimu achikhalidwe a polyolefin (PO), kugwiritsa ntchito filimu ya T-RC kumatha kuchepetsawowonjezera kutenthakutentha ndi 18.6°C, kuonjezera kwambiri zokolola.
2.Porous Materials:
Ofufuza pa yunivesite ya Heriot-Watt ku UK apanga mtundu watsopano wa zinthu zaporous zomwe zingagwiritsidwe ntchito kusungawowonjezera kutenthampweya monga carbon dioxide. Zinthuzi zimakhala ndi mamolekyu opanda khola ngati mamolekyu okhala ndi mphamvu yosungiramo mpweya wambiri. Mwa kuphatikiza makina apakompyuta ndi ukadaulo wanzeru zopangira, nkhaniyi ikuyembekezeka kuchita gawo lofunikira pakugwira ndi kusunga.wowonjezera kutenthampweya.
3. Zida Zatsopano za Insulation:
Ndi kufunikira kwamphamvu komanso kwakukuluwowonjezera kutenthachitukuko, kafukufuku ndi chitukuko cha zipangizo zatsopano zotchinjiriza mkati ndi kunja zikupita patsogolo mosalekeza. Kampani ku Beijing yapanga zida zatsopano zotchinjiriza zakunja ndi zamkati zagreenhouses.Zidazi ndizopepuka, zotsutsana ndi ukalamba, ndipo zimakhala ndi zida zabwino kwambiri zotchinjiriza, zomwe zimapangitsa kuti zikhale zoyenerama greenhouses ambiri, ma solar greenhouses,ndizofunda zotentha.
Ngakhale izi zatsopanowowonjezera kutenthazida sizinali zokwezedwa kwambiri pamsika, ndi kuchuluka kwa kufunikira kwawowonjezera kutenthakupanga bwino, kafukufuku ndi kugwiritsa ntchito zipangizo zatsopano wowonjezera kutentha adzakhala azimuth yofunika kwambiri m'tsogolo chitukuko chaukadaulo waulimi wa greenhouse.
