The United Nations Climate Change Conference in November 2015 resulted in the Paris Agreement where 196 countries agreed to the common goal of reducing the global anthropogenic emissions of greenhouse gases during the second half of the 21st century to zero. The building sector has a large impact on the worldwide production of greenhouse gases as buildings are major consumers of energy from construction through to operations and finally, demolition. Consequently, this considerable potential for savings in emissions will have to be realized. Against this background, sustainable building will receive more attention. Green Buildings, with the emphasis on resource efficiency, comfort and high quality are very challenging for the project participants. In addition, these high demands are even increased due to the requirements of a certification system. This document is intended to provide insights into how to best meet the above. First, by using the example of the German Sustainable Building standard, the process of Green Building certification and its realization in practice are described. Second, after giving a theoretical overview of the principles of sustainability and Lean Thinking through literature review, a practice-oriented examination of the certification process is carried out. And third, sources of waste during the certification process are revealed and an approach for improvement regarding Lean Principles is proposed.
