BuildSysPro: a Modelica library for modelling buildings and energy systems

This paper presents the BuildSysPro Modelica library developed by the department of Energy in Buildings and Territories (EnerBaT) of EDF R&D. After a description of the library’s structure and content, BESTEST validation results and a use case are presented. This library is designed to be used in several contexts including building physics research, global performance evaluation, technology development and impact assessment. It is also a basis for urban and building stock simulation. BuildSysPro is intended for a relatively large audience ranging from R&D scientists to building services engineers. BuildSysPro contains classes to describe the whole building and its energy systems including envelope components, HVAC systems and other energy conversion devices (DHW, thermal and photovoltaic panels...) and boundary conditions models. The models are designed for static and dynamic use, and for the representation of 0D/1D pure thermal and fluid dynamics. BuildSysPro in its current version contains around 380 models and 130 functions.
