ETU Simulation stands for the simple calculation and comprehensible visualization of the building model including the building-coupled plant technology. The standard-compliant evaluation of the building and building services, validated according to ASHRAE Standard 140-2017, can be performed with worldwide climate data. The hourly calculation of heating, cooling and humidity loads enables a meaningful energetic consideration and optimization calculation for all types of buildings.

Simple and fast building simulation (validated according to ASHRAE standard 140-2017)

• Calculation of the thermal behavior (incl. humidity) of buildings in an hourly simulation based on VDI 6007.
• Evaluation of rooms, zones and buildings
• Individual adaptation of prefabricated utilization profiles and extensive building material catalogs incl. ecological factors (e.g. from ÖKOBAUDAT)

Economic efficiency

• Life cycle calculation for existing elements in the simulation
• Calculation of economic efficiency incl. mixed financing and inflation rates
• Profit calculation according to annuities, net present value and terminal value method

Documentation & Presentation

• Output of editable reports
• Flexible output of values and diagrams in image formats and Excel with period selection
• Comprehensible presentation of results for consultations and presentations

Summer thermal protection

• Derivation of summer thermal protection from VDI 6007 according to DIN 4108-2 No. 8.4

System simulation

• CHP, heat pump; heat generator with oil, gas and biomass; PV, solar thermal energy

Cooling simulation

• Calculation of cooling loads of buildings, zones or rooms according to VDI 2078
• Calculation of cooling loads and effects on buildings, zones and rooms
• Manufacturer data & climate data:
  Included in delivery are selected climate data of Germany at certain
  year and time points from MeteoNorm and TRY from the German weather service.
  In connection with a valid software maintenance or user contract also
  own climate data, which comply with the requirements, can be read in.
  The calculations in the respective applications can be carried out manufacturer-specific
  or manufacturer-neutral. Neutral manufacturer data sets are included.
  Specific manufacturer data are only available with a valid software maintenance contract or
  user contract.
  Planning in 3D model

Integrated CAD software:

• Draw floor plans as drawing basis (PDF, DXF, DWG and other image formats) or draw freely
  3D view for visual control after each input
• Define rooms, room stamps and zones simply with a mouse click
• Flexible result output and visual preparation of building models
• IFC interface for importing architectural models
