daylight analysis on Revit house

We followed a tutorial that went over grids, and applying a grid to the floor which would be used to calculate the amount of sunlight that would reach it based on the location and other specifications.


Step 1: import gbMXL file

Step 2: Double check the location is correct, on the right hand side click the project tab.  On the left there will be a site location box, click find. Search for a major city near your location or enter in the latitude and longitude.

Step 3: In the 3D editor tab on the left hand side click the analysis grid icon (an icon that looks like a blue grid).  Click display analysis grid, a blue box will appear on the floor of your model, this grid needs to fit to your floor plan.  To do this select your floor and click auto fit grid to objects.  A box will appear with different options, check the option within, and make sure you are on the XY axis, click OK.  The grid should fit within, and outline your floor.

Step 4: Now you are ready to run the analysis, in the top menu click calculate-lighting analysis.  Select natural light levels-next-over the analysis grid-next-chose your precision (the higher the slower, it took 30 minutes on the setting high)-next-use the default settings for the lux, and overcast sky-next-average-next-regulatory-next-OK

Now it will show with your model with the value range of daylight in a colored graphic on the grid of your model.
