The Opernturm consists of a 42-storey, tower, a 7-storey, podium building facing towards Alte Oper. Access is through an high lobby. The yellow-beige stone cladding of the facades was designed to fit in with the existing buildings surrounding Opernplatz. Designed to consume 23 percent less energy than stipulated by Germany's 2007 EnEV Energy Regulation, the Opernturm was one of the first office buildings in Europe to be certified to the Leadership in Energy and Environmental Design (LEED) Gold standard.
