EnergyPlus Essentials: Mastering Building Energy Simulation

Trace EnergyPlus history from DOE's early models to the open-source engine. Explain why its accuracy, flexibility, and easy integration with Python support its use in building energy simulations.

Open your browser to energyplus.net and go to downloads to access the latest energyplus release. Download the installer for your OS, run the setup, accept the license, and finish.

Install and use Visual Studio Code as your text editor for EnergyPlus projects, follow the simple download and setup process, and add it to your path.

Navigate the EnergyPlus environment, launching EP launch, configuring input and weather files, and reviewing outputs, while managing single or grouped IDF models with VS Code.

Explore energyplus input files (idf) basics, including editing with text editors or the idf editor, navigating sections, classes, objects, and data sets such as Ashrae for materials.

Locate your city on energyplus.net's weather section, download the EPW weather file (the only accepted EnergyPlus weather format), and browse to load it in the EnergyPlus interface.

Define a first EnergyPlus model from scratch by building a simple geometry in IDF, setting location and solar distribution, and selecting inside and outside convection algorithms.

Configure EnergyPlus heat balance algorithms, including conduction transfer function and moisture storage, set time steps and limits, then define site location, climate, design days, and constructions using Azure data sets.

Learn how to define building surfaces in EnergyPlus, from global geometry rules and starting vertex position to surface coordinates, zones, walls, floors, roofs, and windows.

Define fenestrations for the east and west walls using the existing window construction, assign to the corresponding building surfaces, and specify accurate coordinates for proper window placement.

Define people, lights, and equipment in EnergyPlus, and configure schedules and activity levels to support accurate heating and cooling load calculations.

Explore how EnergyPlus models infiltration in a zone, using design flow rate, effective leakage area, or flow coefficient to quantify outdoor air ingress and its energy loss.

Model a simplified EnergyPlus HVAC system using an ideal load air system, set thermostat set points, and apply an availability schedule with auto size for a conceptual design.

Run EnergyPlus simulations, define output variables with the output variable dictionary, and obtain hourly time series data for heating, cooling, and energy use while handling errors and warnings.

Learn to visualize and evaluate EnergyPlus results using the DesignBuilder results viewer, analyzing outdoor temperature, zone mean air temperature, ideal load, and heating, cooling, and electricity metrics.

Learn to design a heat pump HVAC system in energyplus using THP templates, replacing ideal loads with a real system, modeling in the IDF editor, and analyzing results.

Learn to use the text editor alongside the IDF editor for EnergyPlus models, and leverage VS code with the EnergyPlus model kit plugin for color-coded syntax and ready example files.
