The construction industry is one of the largest, most important and resource-intensive economic sectors, and at the same time one of the largest environmental polluters. About 30% of greenhouse gas emissions, approx. 40% of primary energy consumption and approx. 50% of waste is attributable to the building stock (DGNB 2013). In the future, the implementation of sustainable building concepts will gain more importance. The construction industry needs to improve resource efficiency, productivity, waste production and customer value. The aim of this thesis is to present approaches considering the contribution of Lean methods in the context of Real Estate sustainability.
