Who We Are
CES clean energy solutions is a Vienna-based company for technical consulting and advanced engineering solutions, founded in 2008. We deliver integrated innovative solutions for energy efficiency, renewable energy, sustainable buildings, and environmental engineering.
Being a strong partner within the international iC group of companies' networks - well-known for spanning more than 850+ professionals across multiple disciplines, allows our clients to get access to a broad specialist knowledge backed by the full breadth of a multidisciplinary engineering organisation. One team, one vision, one clear responsibility.
We work on a global scale by having international project presence in Austria, Germany, Ukraine, the Western Balkans, Central Asia, and Saudi Arabia, as well as experience in the Caribbean and West Africa. International financial institutions like the World Bank, IFC, EBRD, KfW, the European Union, as well as national governments, and private industry belong to our long-term clients.
Our engineering competences cover four interconnected areas within the frame of the Green Economy Transition: [1] Resource Efficiency & Circular Economy [2] Environmental & Social Compatibility [3] Sustainable Buildings, and [4] Energy & Plants.
How We Work
Systems Thinking: complex topics demand a strong integrative thinking. We involve all relevant stakeholders from the beginning, consider every boundary condition, and work systematically through all possible alternatives, before committing to the desired path.
We work systemically: by identifying root causes and structural problems rather than just applying short-term fixes. We stay ahead: actively tracking and adopting innovations from research, applying regulations, and current market developments.
Our services span the full project lifecycle: from R&D and project preparation through environmental and social assessment, detailed design, construction supervision, investment programme management, and sustainable urban certifications.
Regardless of the project size, we deliver professional and integrated solutions.
