Building Energy Modeling in OpenStudio - Create Geometry

In this video, we discuss how to create building geometry using FloorSpace JS within the OpenStudio application. Transcript: The next task is to create the geometry for the building. First we will save the file as a new file. It is always good to save revisions of files in OpenStudio. That way you can always go back to previous versions if you encounter trouble. Next, we will check our Preferences-Units to ensure that we are working in the English Imperial system. Next, we will go to the Geometry tab on the left. Then go to the top where the Editor tab is. We will be using FLOORSPACEJS to create the geometry. Click New. There are several options to create geometry and use references. For now, we will just create a new floor plan. Next select the Import Image button to import the floor plan. You will want to move the floor plan to wherever your origin is. We will use zero-zero as our origin. Try to locate it as close as possible. Next, you will want to scale the image. You will notice that I put a scaling dimension on the image. This allows us to have a reference for how large the space is. Scale the image by dragging on the corner to adjust it to 120 feet. Next, click outside of the image to lock it in place. We will want to change our grid units to one half of a foot. To create a new space we will click the rectangle button. Click and drag to create the space. When you want to add a new space, click the plus button. You will notice that that the cursor turns red when it locks on to the edge of a previous space. You may skip to 4:30. The community room is an odd shape. We will create it by using multiple rectangles without clicking the plus to add space button. You can see that the rectangles are additive. Now we have our spaces. Next, rename the spaces to reflect what is on our floor plan. Click the expand button. Space 1-1 we will rename to 101 as seen on our floor plan. Go through and rename all of the spaces. You may skip to 6:00. Next, assign space types to each space. Click the drop-down arrow to select the space that is applicable to that room. For space 101, this is going to be the Apparatus Bay. Do this for all of the spaces. You may skip to 7:00. Next, assign construction sets to each space. Since all the spaces are contained within the same building we only have one construction set. For this example we are not going to do a pitched roof or a blow floor plenum. Check the floor to ceiling height. Check the plenum heights. For the Apparatus Bay there is no plenum. For the offices, lockers, storage, etc. we do have a plenum. The community room does not have a plenum. We will not have floor offsets. Now we are finished. Click Merge with Current OSM. Now select the 3D View tab on the upper left. Our model has been created and space types have been assigned. Next video we will continue with creating subsurface geometry on the model and other assignments.
