Legsese Meles Zenawi was an Ethiopian politician and Ethiopia’s Prime Minister from 1995 until his death in 2012. The Gulele Botanical Garden north of the Ethiopian capital is now a memorial park. The Meles Zenawi Foundation is a nonprofit organization established to preserve Meles' spiritual legacy. The foundation is building a campus of five buildings within the park: a panoramic outlook and reception area, a guesthouse, offices, a research center and a library. The buildings were designed by Studio Other Spaces with the Danish-Icelandic artist Ólafur Elíasson. At his request, Transsolar has provided light and shade studies and thermal simulations for adequate daylight and thermal comfort in two of the buildings: the very transparent spiral office building and the guesthouse, which has many wall segments.
