  abstract = {<p>This article reports on our experience in creating Modelica classes that serve as templates for modeling HVAC\&nbsp;<span style="font-size: 13.008px;">systems with thousands of configurations and closed-loop\&nbsp;</span><span style="font-size: 13.008px;">controls. Our motivation is to reduce model creation and\&nbsp;</span><span style="font-size: 13.008px;">parameterization time, provide access to state-of-the-art\&nbsp;</span><span style="font-size: 13.008px;">control sequences, while limiting the risk of error and enforcing\&nbsp;</span><span style="font-size: 13.008px;">modeling best practices. The development of such\&nbsp;</span><span style="font-size: 13.008px;">templates required exploration of class parameterization\&nbsp;</span><span style="font-size: 13.008px;">techniques and data structures for handling large sets of\&nbsp;</span><span style="font-size: 13.008px;">equipment parameters. By describing these issues and the\&nbsp;</span><span style="font-size: 13.008px;">approach taken, we show how the Modelica language can\&nbsp;</span><span style="font-size: 13.008px;">support advanced templating logic. The main limitation\&nbsp;</span><span style="font-size: 13.008px;">we encountered relates to parameter assignment and propagation.\&nbsp;</span><span style="font-size: 13.008px;">The interpretation of parameter attributes at user\&nbsp;</span><span style="font-size: 13.008px;">interface runtime, or the handling of non-trivial constructs\&nbsp;</span><span style="font-size: 13.008px;">involving record classes at compile time is not consistently </span><span style="font-size: 13.008px;">supported by Modelica tools. This leads to choices that are\&nbsp;</span><span style="font-size: 13.008px;">difficult to make when looking for a generic implementation.</span></p>},
