The mapping of large ­volume complex buildings and its interaction of user behaviour, building behaviour and weather situations was previously only possible using complex simulation software.

Thermal multi-zone calculation model that also takes the HVAC system into account has proven useful to CES. The most extensive simulation to date has been made for five model zones for a building with a floor area of 55,000 m² and 54 ventilation devices. The model provides a complete heating and cooling load analysis considering radiation losses and hourly user profiles. Weather data sets by Meteonorm are generally used as a basis, whereby these are compared with local data sets and adopted if required. The average heat exchanger temperature of relevant ventilation devices are defined as the interface to the technical building installations, whereas the calculation differentiates between latent and sensitive cold.

Complex correlations can be shown in a flexible and transparent way using this building simulation model. The high degree of transparency allows the client to verify assumptions and formalisms. This makes the results resilient for prognoses and for the validation of energy efficiency measures as well as the optimisation of building management systems with regard to energy efficiency.

Variation studies can either be produced as graphics or used in table form in accordance with the  parameter variations as a basis for a cost/benefit or lifecycle cost calculation.
