I-Ofisi Yesakhiwo I-D525 Barcelona sisakhiwo seofisi esidalwe ngokuvuselelwa okuzinzileyo kwesakhiwo esikhoyo seminyaka yee-1970. Le projekthi igubungela iimitha ezingama-7,000 ezingamakhulu ezine kwaye iqulethe amanqanaba alishumi eeofisi kunye neendawo zokunxibelelana. Ubuso obuphambili buhlanganisa iifestile ezinkulu kunye neemodyuli ze-Krion ezinemilinganiselo emithathu ze-photocatalytic ezinceda ukucoca umoya. Iindwangu ze-photovoltaic kubuso obusemazantsi zinika umthunzi ngeenyanga ezishushu kwaye zivelisa amandla acocekileyo. Igadi eluphahleni etyalwe ngeentlobo zomthonyama ezisebenzisa okuncinci zongeza ukubandezela kobushushu kwaye ziphucula imozulu yendawo yaloo ndawo.
