<p>Simulation of energy supply and consumption of buildings at the level of districts or even cities not only requires elaborated algorithms but also careful design of model structure and parameters.
Structural aspects include building geometry as well as arrangement of buildings, e.g. to take shadowing and heat transfer into account.
Assigning usage patterns or energy components like heat pumps, PV, boilers, etc. to specific buildings also count as structural aspects of a simulation model.
Moreover, this multitude of model entities has to be defined in more detail by lots of numeric, ordinal or nominal parameters.
Our experience with developing simulation systems like INSEL and SimStadt showed that manual parametrization based on informal data collections, typologies, spreadsheet tables, etc. from different sources is tedious and often hard to reproduce. Instead, parametrization of complex models should be supported by software providing formally defined <strong>parameter catalogs</strong>, that are systematically created and updated by domain experts.</p>
</div>
<div class="paragraph">
<p>Parameter catalogs and the software to create, maintain and deploy them should be independent of any specific simulation software to enhance software modularity (separation of concerns).
Ideally, modelers can enhance their simulation environment by adding suited parameter catalogs as software plug-ins and use them to parametrize model entities easily, e.g. via drag and drop.</p>
</div>
<div class="paragraph">
<p>Automatic parametrization of components in simulation models requires a formal data model which fits the simulation models in terms of content and structure and can pass information to them.
Self-contained parameter catalogs fulfill this requirement by providing an application programmers interface (API) that can be queried for automatic, rule-based parametrization of simulation models.</p>
</div>
<div class="paragraph">
<p>To get good results fast, close collaboration with domain experts and short development cycles are desirable.
We achieved this by exploiting techniques of so called <strong>low code development</strong>.
Basically this means that domain experts encode their knowledge into a graphical diagram defining types of components, their relations, and attributes.
From this diagram, program code for storing and manipulating data sets in main memory as well as code to write and read that data to and from XML files (or data bases) are automatically generated.
A modern graphical user interface to create, read, update, and delete data (CRUD operations) can also be provided with no or very few lines of manually written code.</p>
