I have uploaded an image of the error message to the Autodesk discussion Problem? If so, what are alternative ways for evaluating the radiance image? Radiance is functional, the exporter returned a message saying that theĪpplication 'rview' is missing from the directory. When exporting the file from Ecotect, I noticed that when checking whether contour lines, false color,ĭaylight factors etc.) and get the message 'RGBE read error' Of the options for the information overlay (e.g. See a rendered view of the space in the image viewer, but I cannot run any When I export the Ecotect example file 'RADIANCE_example.eco' I am able to I have been informed that this is the latest Students measured luminace using a false color scale.I have just uninstalled Desktop Radiance and installed the MinGW version on The units of Luminance are candelas per square foot (cd/ft2) or candelas per square meter (cd/mt2). Radiance is used because it provides the option to use weather files and generates results for specific days and hours. The data is exported to radiance and students used contour lines to show illuminance values in Lux or Fc. Additional illuminance calculations are done with with Ecotect and Radiance. Illuminance values can be obtained from Ecotect by assigning a design sky value.ġ.2. The only parameters that affect these daylight fators are the geometry of the design and the materials it is made off, permitting to compare one option with another. This calculation is independent of climate data, so values will not change with different dates or times. This analysis gives a preliminary idea of building performance under a standard overcast sky.

Students do a set of Initial calculations with Ecotect to determine the daylight factor, which is the ratio of indoor to outdoor illuminance. In the US, the foot-candle (fc), or lumen per square foot is used (1 fc = 10.764 lux).

The SI unit of illuminance is the lux, or lumen per square meter. Students calculate interior illuminance using Ecotect.

The objective is to ensure sufficient illuminance with daylight without excessive differences in illuminance values.ġ.1. Students will use Ecotect and Radiance to determine illuminance and luminance levels inside the house. Students must design the fenestrations to achieve the necessary illuminance levels while minimizing glare. Illuminance is a measure of the illumination of a surface and luminance is a measure of brightness of a surface when looked at from a given direction. > Building Form / Integrated Design Overview Visit this link to see the projects sorted by the carbon related topic
