Plugin "Insolation Calculation" - allows you to make an approximate calculation of insolation on the points that you designate with a special family of "Insolation Ball" and so you can use the sun, which is embedded in the standard functionality of Revit, to make a calculation of insolation on your object.
1. Loading of the insolation ball family into the model
The first thing we will do is load the insolation ball family. To do this, open the plugin settings.
As a result, the insolation ball family in the Generalized Model category will be loaded into your project.
2. Creating an environment.
The next step is to create the environment. Since the calculation of insolation is a calculation of the amount of time during which the sun's rays hit a particular point. Accordingly, the barrier to the sun's rays and is the environment, ie the neighboring building blocks the direct hit of these rays.
So, the environment we will do with the standard Revit functionality, namely with the help of forms. If you have never worked with this tool, please check out the video on YouTube or Revit Help. There is nothing complicated, the main thing is to "squeeze" cubes of the current building and neighboring buildings.
Suppose we have the following environment.
3. Placement of insolation ball families
We have the environment ready. The next task is to place families of our insolation balls in the project at the points by which we are going to count insolation. In our example, let it be "some" window of "some" apartment #58.
Let's go to the corresponding plan (for example, on the 2nd floor) and put the family of our insolation ball at the location of the window of this apartment. Let's put 2 families for example.
4. Setting coordinates.
Since we will be calculating using the standard Revit functionality, namely the sun, and the sun has a different path in different points of our planet, we first need to set up the correct position of our project in the world.
It is absolutely necessary to correctly locate your site in the world. We do this using the standard Revit functionality, specifically here:
In the opened window select the city of your site location accordingly.
Now you need to specify the rotation angle of your site. We do this by specifying the angle of rotation in the base point of the project.
In our case we will put 45 degrees.
If you don't know where to find the project base point, go to the 3D view and find it in the override of graphics visibility in the General Plan category.
5. Sun Setting.
There is only 1 step left before we start working with the plugin. All that is left is to set up our sun on the plan on which we are going to work. So, go to the plan on which we placed our insolation balls, and then click on the button for setting the sun.
In the opened window, you need to make all the settings as follows:
1. Set 1 day
2. Set the settlement date.
3. Check the sunrise to sunset box.
4. Set the calculation of 15 minutes.
5. Set the level of the 1st floor for example.
6. Press ok.
Now let's turn on the sun on our open plan.
As a result, this is roughly what your plan should look like.
6. Setting the parameters
Before running the plugin, do one more operation.
Specifically: for example, let's set the Mark parameter of our insolation balls to indicate whether they belong to a particular apartment or room. I.e. just fill in the "Mark" parameter.
This filling will be useful for us in order to be able to determine its belonging to this or that room by the created hatching. And also, if you need, you can use it to calculate the total amount of insolation for a particular apartment or room with the help of the specification.
We also need to add a couple of project parameters for the category "Node elements".
One parameter should be textual and called, for example, "Room number" and the second one should be numerical and called, for example, "Time". You can add these parameters manually using the standard Add Project Parameters functionality in Revit.
Instructions for adding a text parameter are below, for the numeric parameter we do the same, but specify the data type "Number" and the corresponding parameter name
7. Plugin operation
Launch the plugin on the BS_АR line
In the opened plugin, make the following setting:
1. Select the format of work: By all balls or only by selected ones. If only by selected ones, they should have been selected before launching the plugin.
2. If you don't want to use all forms for the plugin to work, but only those visible in the current view, then check the box here.
3. Select our insolation balloon family. If you suddenly use some family of your own, you need to select it.
4. Select the type of hatching. It will be needed to create the insolation petals on the plan.
5. Specify the petal diameter for the hatching that will be built on the plan.
6. Set the multiplicity in minutes, you can choose 15,5,3 or 1 minute. The less we set, the more accurate the calculation will be, but longer the plugin will work.
7. If you want to see on the 3D view of the extreme rays of the petals, which fall from the sun to your family insolation balloon, check this box.
8. If you specified a check mark in step 6, you can specify the length of these edge rays.
9. Specify the parameter where the total insolation by point will be written. I.e. this is the parameter of the insolation ball family.
10. If you want the insolation information to be recorded also in the hatch petals, check this box.
11. Specify the parameter of the insolation balloon where the room number is recorded. In our case, this is the "Brand" parameter.
12. Specify the parameter of the hatch where you want to record the room number from the insolation ball.
13. Specify the hatching parameter where to record the insolation time for one petal.
14. Click Done!
As a result, we get hatching petals in our plan.
Consequently, each of the lobes shows in the form of a sweep the insolation at the point where it passes and where it breaks.
Look at the parameters. Choose one hatching lobe.
