DGNB criteria technical quality

DGNB criteria "Ease of cleaning building components" (TEC1.5)


Our objective is to implement structural and technical measures to reduce the cost and effort required for cleaning.


The issue of how a building structure can be cleaned has a significant effect on the costs and environmental impact of a building during its use. Surfaces that can be easily cleaned require fewer cleaning agents and result in lower cleaning costs.

Indicators for evaluation

  1. Accessibility of the exterior glass surfaces

  2. Exterior and interior components

  3. Floor covering

  4. Dirt trap

  5. Unobstructed floor plan

  6. Surfaces

  7. Concept for ensuring ease of cleaning
