Eco Smart Home supports the values and principles of the German Society for Sustainable Building (DGNB) and hopes that, by being a member, it can help promote sustainability in construction. The DGNB has committed itself to making the general public aware of sustainable building methods. For this reason, the DGNB certifies buildings that can provide proof of their sustainability. At Liberty Group, it is not just one building that has been certified; a whole construction system has received the DGNB Multiple Certificate in Gold.
The DGNB certification system for sustainable construction is used to provide an objective description and evaluation of the sustainability of buildings and accommodation. It assesses quality in the wider sense of the term, across the complete life cycle of the building, and considers all the essential aspects of sustainable construction. These cover the six areas of ecology, economy, sociocultural and functional aspects, technical quality, processes and location.
