Due to more recent thermal networks incorporating meshing decentralised heat and cold sources, the system often has to deal with variable temperatures and mass flow rates, with flow reversal occurring more frequently. This paper presents the mathematical derivation and software implementation in Modelica of a thermo-hydraulic model for thermal networks that meets the above requirements and compares it to both experimental data and a commonly used model. Good correspondence between experimental data from a controlled test set-up and simulations using the presented model was found. Compared to measurement data from a real district heating network, the simulation results led to a larger error than in the controlled test set-up, but the general trend is still approximated closely and the model yields results similar to a pipe model from the Modelica Standard Library. However, the presented model simulates 1.7 (for low number of volumes) to 68 (for highly discretized pipes) times faster than a conventional model for a realistic test case. A working implementation of the presented model is made openly available within the IBPSA Modelica Library. The model is robust in the sense that grid size and time step do not need to be adapted to the flow rate, as is the case in finite volume models.&lt;/p&gt;</style></abstract><custom2><style face="normal" font="default" size="100%">2001049</style></custom2></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Thierry Stephane Nouidui</style></author><author><style face="normal" font="default" size="100%">Klaus Sedlbauer</style></author><author><style face="normal" font="default" size="100%">Christoph Nytsch-Geusen</style></author><author><style face="normal" font="default" size="100%">Kurt Kießl</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Neue objektorientierte hygrothermische Modell-Bibliothek zur Ermittlung des hygrothermischen und hygienischen Komforts in Räumen</style></title><secondary-title><style face="normal" font="default" size="100%">Bauphysik</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><number><style face="normal" font="default" size="100%">5</style></number><volume><style face="normal" font="default" size="100%">31</style></volume><pages><style face="normal" font="default" size="100%">271-278</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Christoph Nytsch-Geusen</style></author><author><style face="normal" font="default" size="100%">Thierry Stephane Nouidui</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Gebäudesimulation mit adaptiven Modellierungsansätzen</style></title><secondary-title><style face="normal" font="default" size="100%">BAUSIM 2008</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2008</style></year></dates><pub-location><style face="normal" font="default" size="100%">Kassel, Germany</style></pub-location><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Thierry Stephane Nouidui</style></author><author><style face="normal" font="default" size="100%">Christoph Nytsch-Geusen</style></author><author><style face="normal" font="default" size="100%">Andreas Holm</style></author><author><style face="normal" font="default" size="100%">Klaus Sedlbauer</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Object-oriented hygrothermal building physics library as a tool to predict and to ensure a thermal and hygric indoor comfort in building construction by using a Predicted-Mean-Vote (PMV) control ventilation system</style></title><secondary-title><style face="normal" font="default" size="100%">8th Nordic Symposium on Building Physics in the Nordic Countries 2008</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2008</style></year></dates><pub-location><style face="normal" font="default" size="100%">Copenhagen, Denmark</style></pub-location><volume><style face="normal" font="default" size="100%">2</style></volume><pages><style face="normal" font="default" size="100%">pp.825-832</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The indoor temperature and humidity conditions of the building envelope are important parameters for the evaluation of the thermal and hygric indoor comfort. In the research project GENSIM a new hygrothermal building library, based on the object- and equation-oriented model description language Modelica® has been developed by the Fraunhofer Institutes IBP and FIRST. This library includes many models as for instance a hygrothermal wall model, an air volume model, a zone model, a window model and an environment model. Due to the object-oriented modelling approach, some models of this library can be configured to a complex hygrothermal room model, which can predict the time dependent indoor temperature and humidity conditions in a building construction. In this paper we will introduce in a first step the object-oriented hygrothermal room model of this library. In a second step, the validation of the room model with some field experiments will be shown. In a third step we willpresent some simulation results, we obtained by coupling the room model with an implemented Predicted-Mean-Vote (PMV) control ventilation system to predict and to ensure a thermal and hygric indoor comfort in one case study. In the conclusion, the possible range of future applications of this new hygrothermal building physics library and demands for further research are indicated.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Christoph Nytsch-Geusen</style></author><author><style face="normal" font="default" size="100%">Thilo Ernst</style></author><author><style face="normal" font="default" size="100%">Peter Schwarz</style></author><author><style face="normal" font="default" size="100%">Mathias Vetter</style></author><author><style face="normal" font="default" size="100%">Andreas Holm</style></author><author><style face="normal" font="default" size="100%">Juergen Leopold</style></author><author><style face="normal" font="default" size="100%">Alexander Mattes</style></author><author><style face="normal" font="default" size="100%">Andre Nordwig</style></author><author><style face="normal" font="default" size="100%">Peter Schneider</style></author><author><style face="normal" font="default" size="100%">Christoph Wittwer</style></author><author><style face="normal" font="default" size="100%">Thierry Stephane Nouidui</style></author><author><style face="normal" font="default" size="100%">Gerhardt Schmidt</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Advanced modeling and simulation techniques in MOSILAB: A system development case study</style></title><secondary-title><style face="normal" font="default" size="100%">5th International Modelica Conference</style></secondary-title><tertiary-title><style face="normal" font="default" size="100%">2006</style></tertiary-title></titles><dates><year><style  face="normal" font="default" size="100%">2006</style></year></dates><pages><style face="normal" font="default" size="100%">pp.63-72</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Christoph Nytsch-Geusen</style></author><author><style face="normal" font="default" size="100%">Andre Nordwig</style></author><author><style face="normal" font="default" size="100%">Mathias Vetter</style></author><author><style face="normal" font="default" size="100%">Christoph Wittwer</style></author><author><style face="normal" font="default" size="100%">Thierry Stephane Nouidui</style></author><author><style face="normal" font="default" size="100%">Peter Schneider</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">MOSILAB: Ein Modelica-Simulationswerkzeug zur energetischen Gebäude- und Anlagensimulation</style></title><secondary-title><style face="normal" font="default" size="100%">16.
