TY - CHAP A1 - Brennig, Thomas A1 - Sanio, Hans-Peter T1 - New Methods of Computer Aided Optimization of Investment and Operating Costs for Buildings During Their Useful Life N2 - Current software solutions for real estate planning, construction and use, do not model the complete life cycle of a building. Well-integrated software tools exist for the planning and construction phases. Data integrity exists throughout the planning and construction phases, but problems occur at the transition to the use-phase. At this interface, the complete data set of planning and execution gets lost. Another software deficiency is that current software solutions don’t handle construction work and maintenance work equally. This is why a new software generation is demanded, which continuously covers the entire workflow process from the planning phase to the demolition of a building. New data concepts have to be developed, which allow bringing work items for construction together with work items for real estate use.
