DGNB criteria "Life cycle cost"


Our objective is sensible and conscious use of economic resources throughout the entire life cycle of a building. In the conception and planning phases of implementation of a building, there are areas of significant optimisation potential for later economic management. The parties involved in the planning process should regularly focus on possible follow-up costs associated with their design and implementation variants from an early stage in the planning phases.


In addition to yields from the production and exploitation costs, the economic viability of a building depends on cost-efficient operation. To this end, the life cycle cost calculation enables the medium-term to long-term costs of a building to be taken into account. Carrying out the life cycle cost calculations and communicating them to the parties involved in planning more regularly and earlier in the planning process increases the likelihood of achieving solutions optimised for cost-efficiency in the long term. This method can also serve as a basis for determining a transparent cost comparison for buildings with similar usage and functionality, which can be used as a guide for the performance of the project under development. For this step, the life cycle cost calculation is performed on the basis of fixed parameters in accordance with defined conventions, and can then be used comparative assessment using appropriate benchmarks.

Indicators for evaluation

  1. Calculations of the life cycle costs in the planning process

  2. Life cycle cost optimisation

  3. Building-related life cycle costs
