Optimization of buildings throughout their life cycle, minimization of the energy consumption, reduction of the environmental burden and improvement of the total economic efficiency.

In order to reach a climate-neutral building stock by 2050, the building sector must be considered. Important measures for the reduction of the need for thermal heat have to be taken – with the help of energy-efficient modernisation of buildings and also for new buildings. However, environmental impact respectively CO2 emissions do not only arise during the usage phase but already within the building phase as well as during disposal (keyword: “grey” energy). There are many publications regarding this topic, which come to differing conclusions according to perspective, balance limit and basic assumptions made.
The Bavarian Ministry of Economic Affairs and Media, Energy and Technology commissioned a study assessing the different types of constructions in regard to their total impact on the environment and their energy footprint in the course of their total life cycle. The acquired information should contribute to the optimization of a building throughout its total life cycle, to minimizing of the consumption of energy and resources, to the reduction of the environmental burden and the improvement of the total economic efficiency.

The results are to be presented objectively based on scientific results and edited for the target audience (planner, architect, citizen) accordingly. The stakeholders are to receive information about the environmental impact of different construction types, in order to be able to make specific decisions about the energy-efficient and ecological optimisation of the life cycle of a building under consideration of economic efficiency.
