Wiebke Kirchhof has completed the DGNB auditor training course at the DGNB (German Sustainable Building Council) and successfully completed it in February 2024. She is now an expert in the planning and construction of sustainable buildings and is therefore authorized to carry out sustainability certifications on properties (districts, interiors and buildings) and can accompany projects according to the DGNB system throughout the entire certification process. During an assessment, ecological, economic and socio-cultural aspects of buildings are analyzed and evaluated. The Green Office is thus expanding its area of expertise and is actively committed to ensuring that buildings are planned, constructed and operated in such a way that they make an active contribution to climate protection and have a positive impact on sustainability goals.
