Andreas Dreisiebner
Andreas Dreisiebner is a Swiss entrepreneur and sustainability innovator, leading A777 Gartengestaltung (Zurich) since 1992.
Originally trained in landscape architecture, he gradually expanded his work into urban green infrastructure — including green roofs, vertical gardens, and integrated renewable energy systems.
As a board member of Solarspar, Andreas has been actively involved in R&D projects focused on combining solar technology with biodiverse rooftop greening — even under extreme environmental conditions.
Since 2015, he has represented Switzerland as Vice-Chair of the Group of Experts on Renewable Energy at the United Nations Economic Commission for Europe (UNECE).
His work reflects a deep commitment to merging ecological principles with technical innovation — proving that sustainable development is not just about efficiency, but also about care for future generations.
