Abstract

At the Modelica 2009 conference; we introduced the Buildings library; a freely available Modelica library for building energy and control systems.

This paper reports the updates of the library and presents example applications for a range of heating; ventilation and air conditioning (HVAC) systems. Over the past two years; the library has been further developed. The number of HVAC components models has been doubled and various components have been revised to increase numerical robustness.

The paper starts with an overview of the library architecture and a description of the main packages. To demonstrate the features of the Buildings library; applications that include multizone air ow simulation as well as supervisorand local loop control of a variable air volume (VAV) system are brie y described. The pap closes with a discussion of the current development.
