Join us for Energy Trust New Building’s August Building Energy Simulation Forum. 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 that produce detailed operation schedules, informing the whole building energy use and daylighting impacts of multiple shading systems.
