M'zaka zaposachedwa, anthu ochulukirachulukira awonetsa chidwi kwambiri pamitengo yopangira, chifukwa mitengo yopanga simangokongoletsa chilengedwe, komanso kuyeretsa mpweya. Kumera kwamitengo yopangirako kwabweretsa mphamvu zatsopano zomwe zimayambitsa kubiriwira kwamizinda.
Pali zifukwa zambiri zomwe mitengo yopangira imakondedwa.
Choyamba, mitengo yochita kupanga imatha kutengera mawonekedwe ndi mtundu wa zomera zenizeni, kupangitsa malo obiriwira a m'tauni kukhala okongola kwambiri.
Kachiwiri, mitengo yochita kupanga sifunika kusamala kwambiri, sidzakhudzidwa ndi masoka achilengedwe, ndipo ikhoza kukhalabe yabwino kwa nthawi yaitali.
Chofunika kwambiri n'chakuti mitengo yochita kupanga imatha kuyeretsa mpweya, kutulutsa mpweya wa okosijeni, ndi kukonza malo akutawuni.
M'dziko langa, mitengo yopangira yagwiritsidwa ntchito kwambiri m'malo opezeka anthu ambiri monga m'mapaki, mabwalo, ndi malo ogulitsira. Anthu amatha kuyamikira mitengo yochita kupanga yamitundu yosiyanasiyana m'malo awa ndikumva kukongola komwe kumabweretsa.
Maonekedwe a mitengo yochita kupanga sikuti amangopangitsa mzindawu kukhala wokongola kwambiri, komanso amathandizira pakuteteza chilengedwe. Tikukhulupirira kuti m’masiku akudzawa, mitengo yochita kupanga idzakhala yogwiritsidwa ntchito kwambiri ndi kulimbikitsidwa.
