Features

The BuildingSystems library has a flexible modelling architecture and can be used for a large spectrum of modelling and simulation purposes.

General features

  • Supports the present Modelica language version 3.3
  • Its a Open Source library (BSD 3-Clause License)
  • Is being developed under Dymola
  • Runs partly with the Open Source simulation tools OpenModelica and JModelica (you can see here an example)
  • Uses the Modelica IBPSA Library as a core layer
  • Includes databases for weather data, building materials, building constructions and energy plant components

Building simulation

  • Component based and hierarchical modelling approach (models of building elements, single zones, multi-zone buildings, districts)
  • Zones and building models with a different levels of detail (low-order models, 1D, 3D)
  • Thermal and hygrothermal building models

Room simulation

Thermal room simulation model which uses the 3 dimensional modelling approach of the library.

Building simulation

Thermal building simulation model of an office storey with 13 thermal zones which uses the 1 dimensional modelling approach of the library.

District simulation

District model which consists of a lot of low-order building models of the library.

Energy plant simulation

Solar thermal system

Model of a solar thermal system, in which the thermal energy of the collector is transferred with an external heat exchanger into a hot water tank.

Integrated building and plant simulation

Photovoltaic cooling system

Model of a photovoltaic cooling system which supplies a building with cooling energy. For this purposes a PV generator produces electricity which is partly stored in a battery. An electric driven compression chiller generates cold water which cools the building by a cooling surface.
