Thatha izakhiwo zoshishino, iibhloko ezisebenzayo kunye namaziko ommandla njengabathwali abaphambili bokuphuhlisa kunye nokuqeshisa izakhiwo ukwazisa amashishini ahlukeneyo, ukwenzela ukwazisa imithombo yerhafu kunye nokuqhuba uphuhliso loqoqosho lwengingqi.Ukusetyenziswa kwamandla onyaka kwizakhiwo zeofisi kubalelwa malunga ne-10% yosetyenziso lukazwelonke lulonke, kwaye ukusetyenziswa kombane wonyaka kwizakhiwo ezininzi zeeofisi kungaphezulu kwe-1 yezigidi ze-KWH.Ngoko ke, izakhiwo zorhwebo zifuna ukuthembeka okuphezulu kakhulu kokunikezelwa kwamandla.Izakhiwo zorhwebo ngokubanzi (ngokukodwa ezimelwe yi-super high-rise) zixhotyiswe ngemithombo yombane emibini ezimeleyo, kodwa ngaphakathi kwazo ziqulethe imithwalo ebaluleke kakhulu.Xa enye inkqubo yonikezelo lwamandla iphantsi kogcino okanye isilela, enye inkqubo yonikezelo lwamandla iya kusilela kakhulu.Ngeli xesha, iseti yejeneretha yedizili iqwalaselwe ngokubanzi njengamandla kaxakeka.

Njengoko inkqubo yokufudukela ezidolophini iqhubela phambili, ishishini lokwakha (ingakumbi elimelwe lulwakhiwo oluphezulu oluphezulu) lubeke phambili iimfuno eziphezulu kwisiqinisekiso sokusebenza kakuhle kwamandla, kwaye iiseti zejenereyitha ziya kusetyenziswa ngakumbi njengamandla okugcina kwiiprojekthi ezahlukeneyo ukunceda uphuhliso ishishini.
