Derivation of heating load profiles on the basis of demand-consumption analyses

Without having extensive measurement equipment installed, only annual or monthly values of the energy
consumption of existing buildings are usually available. The same applies to demand analyses, for which usually
monthly and annual values for net, final and primary energy requirements are calculated. However, a higher
temporal resolution of the consumption/demand data can be an important decision-making assistance both in the
design of new buildings and in the planning of renovation and reconstruction measures. However, the
determination of the time-resolved energetic behavior of buildings with the help of dynamic simulation models is
very complex. As an alternative, a method was developed that allows hourly heating load and final energy profiles
to be derived on the basis of comparatively simple approaches. The method was tested using an existing building
in the local heating network of Kassel University, on a new building of the university campus being in the planning
phase as well as on the new institute building of Fraunhofer IEE being recently completed.
