In assessing the sustainability of a building according to DGNB, the aspect of “costs of the building in its life style” plays a crucial role. Minimising life cycle costs (LCC) is a primary sustainability objective.
An LCC analysis determines the total costs caused by a building during the course of its life cycle, from construction to demolition. DIN standard 276 regulates the determination of costs in building construction. In the LCC analysis, by definition, the cost groups “300 Structure – Construction” and “400 Structure – Technical installations” are considered.
These two cost groups form the basis for a very detailed and objective consideration of the planning, financing, production, usage, renewal and demolition costs incurred during the life cycle of the building.
In the LCC analysis, the investment and operating costs over a period of 50 years are precisely determined and calculated.
