Observations and Points of Friction When Working With: Complex Models in ESP-r

Jon Hand

Abstract: General purpose simulation environments such as ESP-r are typically used in projects of moderate complexity (e.g. a few dozen thermal zones and control loops and mass flow network nodes). Complexity beyond this norm has costs, but the specific nature of the frustrations and extra resources associated with complex models has not been documented and the causal factors investigated. This paper uses a complex building, as a case study to identify instances where the ESP-r interface, data structures, model reporting or user working methods introduced friction into the work flow. Points of friction within the model creation process were documented, alternatives (either a software patch, data structure change or a provision for more feedback to the user) implemented and evaluated. Roughly 200 patches were made made coping with mind-boggling levels of detail more tractable. It also discusses where the information included and excluded from CAD drawings and specification impacts deliverable in large projects.
