The New Illuminance Map tool creates a new OpenStudio Illuminance Map object. This consists of a rectangle with a grid representing map data points. By default it will be placed 30 inches above the surface you click on. You can move and resize the Illuminance Map with the SketchUp Move and Scale Tool and through the Object Inspector. To obtain data reported for the map in EnergyPlus, you also need to include a Daylighting Controls Object and lights. Most space types in the template files already include a light object.You can create an illuminance map from within a space, or you can copy and paste the map into a different space. You can have multiple illuminance maps in a space.
