Annual Energy and Daylight Co-Simulation for More Accurate Representation of Electric Lighting and Shading Controls in Buildings

Description:

Shading controls are typically not included in energy modeling and often not considered in daylight modeling. Similarly, electric lighting is usually represented as a fixed schedule or with the use of simplified daylight harvesting calculations. EnergyPlus approaches this with the split-flux method while Radiance employs a more accurate ray-tracing technique.

This presentation will discuss a co-simulation workflow between EnergyPlus and Radiance in a mid-rise commercial office project. This work includes a series of energy and daylighting simulations which derive detailed operation schedules and informed the whole building energy use and daylighting impacts of multiple shading systems.

Learning Objectives:

1. Explore the potential of co-simulation between two industry-standard building simulation tools, EnergyPlus and Radiance.
2. Understand ways to incorporate co-simulation in your own simulation workflows.
3. Be able to integrate shading and electric lighting controls results between EnergyPlus and Radiance.
