“(Co-)simulation platform to enable interaction between new and existing programs to predict the energy demand, generation, storage and management of groups of buildings.” ‒ use of GIS and BIM data ‒ modular structure ‒ open source ‒ extensible
Key features
‒ research-level usability
‒ no front end / graphical interface ‒ no out-of-the-box functionality
‒ modules are selected and combined as needed ‒ never all used at once

Multi-model ecology a group of models and datasets co-evolving within the context of a dynamic socio-technical environment
Aims to facilitate the cultivation of a set of resources that can be configured and reconfigured in different ways to address a problem from different perspectives, and which evolves over time as knowledge and needs change.

‒ Use open standards and open software ‒ Document, and use documentation standards ‒ Build simple components (represent complexity modularly) ‒ Leverage the Web, but recognize its limitations ‒ Prioritize flexibility over completeness ‒ Borrow proudly, acknowledge your role

Current ontological structure
Aim To enable efficient navigation of information about models and datasets, facilitating model reuse and integration
Semantic Wiki = Wiki + Graph Database
collecting distributed and changing knowledge
describing structure: subject-predicate-object

Facilitating model reuse and integration in the urban energy simulation platform L. Andrew Bollinger and Ralph Evins Submitted to Simulation of Large-scale Complex Urban Systems conference, Reykjavik, Iceland, June 2015
Uses / benefits ‘Bringing the platform together’: ‒ Resources located in different places / formats Collecting scripts and datasets that were used together for a specific end use (e.g. a case study or a publication) Classing scripts and datasets to make them easier to find / reuse Automating (some) documentation: ‒ Deriving interactions directly from code ‒ Retrieving meta-data & comments from code
![Page 9: Introducing the Holistic Urban Energy Simulation platform ... · L. Andrew Bollinger and Ralph Evins . Submitted to Simulation of Large-scale Complex Urban Systems conference, Reykjavik,](https://reader036.fdocuments.us/reader036/viewer/2022081401/5f078aee7e708231d41d80ac/html5/thumbnails/9.jpg)
Set of Python & MatLab scripts that link existing simulation programs ‒ Modular, extensible, cluster-deployable ‒ Flexible: reconfigurable to serve many use-cases (no single platform…) ‒ Reusability through use of common structure (edit, run, retrieve….) ‒ Compatible with Git ( / BitBucket / SourceTree) for cloud-based version-tracking
Why Python & MatLab? ‒ Common tools: new people are likely to be familiar with one or the other ‒ (Relatively) easy to use, but (relatively) powerful ‒ Extends existing codebase ‒ Avoid other languages (where possible) to keep it simple
Implementation
‒ Fully open-source (free for industry) ‒ More powerful (in rare circumstances) ‒ New(ish), rising popularity
‒ Available for academics (costly for industry) ‒ Easier to use (depending on experience) ‒ More established
