Relevance of construction products in the DNGB System
The DGNB sustainability concept. A new quality of building.
The DGNB assesses buildings and urban districts which demonstrate an outstanding commitment to meeting sustainability objectives. The sustainability concept of the DGNB System is broadly based and goes beyond the well-known three-pillar model. The DGNB System covers all of the key aspects of sustainable building: environmental, economic, sociocultural and functional aspects, technology, processes and site. The first four quality sections have equal weight in the assessment. This means that the DGNB System is the only one that gives as much importance to the economic aspect of sustainable building as it does to the ecological criteria. The assessments are always based on the entire life cycle of a building. Of course the focus is always also on the wellbeing of the user.
It is crucial that the DGNB does not assess individual measures but instead the overall performance of a building or urban district.
Construction products. Key building blocks for sustainable building.
Construction products make an important contribution to the sustainability and the overall performance of a building – through their environmental impact, such as emission of pollutants or consumption of energy during manufacturing and operation; their life cycle costs, which can be significantly affected by inspection and maintenance costs or time and money spent on cleaning; and their effect on user comfort.
Based on the DGNB catalogue of criteria, below we list aspects of sustainable building that can be affected by construction products.
