Amandla okushisa elanga akhishwa inyumbazane kusukela ekwakhiweni kwe- amandla avuselelekayo. Ukumiswa komkhakha wezezakhiwo kuvimbele lo mkhakha ukuthi ukhule ngezinga elilindelwe nguHulumeni lamaphaneli elanga angama-5 million m2 oHlelo luka-2005-2010.
Ngisho ukufakwa kwi-Technical Building Code, i-CTE, kusukela ngo-2006, kwesibopho sokufaka amaphaneli elanga emakhaya amasha noma ezakhiweni ezivuselelwe akuzange kube wusizo ekufakeni amaphaneli welanga amaningi eSpain. I-CTE idinga ukuthi phakathi kwamaphesenti angama-30 nama-70 wokusetshenziswa kwe amanzi ashisayo yamakhaya amasha aqhamuka emanzini ahlanzekile afudunyezwa ngamapaneli elanga, kepha isilinganiso siwele ezindlebeni ezingezwa ngenxa yokungabi bikho kokwakha okusha. Ngokwengxenye yayo, imikhandlu yamadolobha engaphezu kwama-50 kulo lonke elaseSpain nayo inezimiso ezinesilinganiso esifanayo.
Lesi simo senze izinkampani zamandla kagesi ezishisayo elanga, ngosizo lwe-IDAE, zaphambukisela amehlo azo kwenye indawo yomphakathi engadinga lolu hlobo lwamandla noma olungayisebenzisela okunye ukusetshenziswa. Yilapho ezinye izakhiwo ezifana izibhedlela, izindawo zokuhlala ze-terecera ubudala nangaphezulu izikhungo zokuthenga lokho kungaba ngamakhasimende angaba khona walolu hlobo lwamandla avuselelekayo. Ngokwengeziwe, ubuchwepheshe obukwazi ukwenza amandla elanga azuzise hhayi kuphela ukuthola amanzi ashisayo nogesi, kepha futhi nokupholisa, kuyathuthukiswa, okungukuthi, hhayi ukushisa kuphela kepha nokubanda.
Ngokuya nge-IDAE, amandla okushisa elanga anganelisa Amaphesenti angama-80 wamanzi ashisayo asekhaya asetshenziswa yisibhedlela namaphesenti angama-60 wamandla kagesi adingekayo ukushisa lesi sakhiwo.
Lezi zikhungo zezempilo zingafinyelela futhi nasezimalini nosizo olunikezwa yi-IDAE kanye nemiphakathi ezimele, kwesinye isikhathi ifinyelela kumaphesenti angama-40 esamba semali esetshenzisiwe, lolu sizo luqoqwa. Lezi zibonelelo zihlukile esifundazweni ngasinye.
