Event Details

EnergyPlus for Practitioners (September 23-24)

This two-day workshop focuses on the needs of the energy modeling practitioner in order to get you up to speed and highly productive with EnergyPlus as quickly as possible. We cover the fundamentals of EnergyPlus such as geometry and internal loads while rapidly ramping up to advanced topics such as HVAC systems and controls. We guide you through the complexities of the EnergyPlus syntax, input/output files, documentation, and essential software tools including the Euclid extension for SketchUp. Most importantly, we teach you how to use the available resources to teach yourself going forward. Demonstrations and hands-on exercises are used extensively throughout. By the end of the workshop, you should be comfortable with creating, running, and debugging EnergyPlus models.

We have developed our training materials from scratch over a period of several years based on our extensive experience using EnergyPlus to model real-world projects and helping others to do the same. This workshop should be a prerequisite for anyone planning to work with EnergyPlus regardless of what user interface you choose.


Modelkit for EnergyPlus (September 28)

This one-day workshop teaches you to use the Modelkit framework developed by Big Ladder Software for generating EnergyPlus input files. We cover the basics of how Modelkit uses the Ruby programming language in combination with a library of templates to highlight the benefits of these features. We then describe the process of templates being combined together in order to compose the EnergyPlus input file, and how parametric values can be set in one template and passed to another. For example, changing an HVAC system type from "CAV" to "VAV" would require changing a single parameter -- the templates are pre-configured to update EnergyPlus object types, inlet/outlet node connections, and other details accordingly.

We culminate with Big Ladder Software's Modelkit Excel tool that simplifies parametric analysis by allowing users to set parametric values in a spreadsheet tool and apply the Modelkit framework to automatically compose and simulate EnergyPlus input files, as well as compare user-specified results between simulations. By the end of the workshop, you should be comfortable with creating and simulating EnergyPlus input files using the Modelkit framework. Demonstrations and hands-on exercises will be used extensively throughout to generate models with a range of energy-efficiency measures and HVAC system configurations.

Previous experience with EnergyPlus is recommended but not required. You are welcome to register for this workshop separately from the EnergyPlus for Practitioners workshop.
