We can separately import some design days. Now these will come along with the zip file that you just downloaded. Those will appear on each of the pages. Let me show you by demonstrating. Can I undo it? If I look for an Undo function here in the menus, again, there is no Undo. So that is something that is relatively unusual in the modern kind of era of software.

Click on the My Dashboard near the top right of the website. Copy the text after API v1. You only need to configure the key in one place and it will be used globally throughout the OpenStudio Application tools. Additionally, this key will be maintained when you install updates to the OpenStudio Application. About: Click on the diagram above to view a larger version.

Introductory Tutorial The tutorial below was created before the grid view was added to the Space Types and Thermal Zones tabs. Selecting a Library for Constructions, Loads, and Schedules Libraries that are included with the OpenStudio Application contain data for constructions, loads, and schedules for 6 vintages across all U.

Above: Load a new Library using the menu. It automatically populates the construction set to all of the space types that were selected. This construction set is basically saying what type of constructions these spaces will have. You can customize these by creating additional construction sets. To create additional construction sets, please see the previous video. Next, you will notice that the space type has a schedule set and an outdoor design specification outdoor air.

This is the ventilation specification. It tells the energy model how much ventilation is required for that space. On this column, you will see space infiltration design flow rates. The space infiltration design flow rates are also specified. You can change the flow rates based on floor area, total space, exterior surface area of roof and walls, exterior walls, or air changes per hour. To create a different infiltration rate, just rename it and change the values to what you want. Similarly, you can copy those just like we just did with the check boxes.

We will apply an infiltration rate to the space plenums. You can see the final column is a Space Infiltration Effective Leakage area. We will not be using this, but I will illustrate how to find information about this input for the program. Next, select Effective Leakage Area or you can click the link. This describes what the Effective Leakage Area is. Essentially, it is saying that this is a different way to calculate infiltration rates and it is normally used for smaller residential type buildings.

We will not be using this for our project. We will only be using Space Infiltration Design Flow rates. Next, you can go to the loads tab up at the top to see what type of loads have been applied to the each individual space. For our Apparatus Bay, we have lighting load definition and an associated schedule for lights. Likewise we have electrical equipment loads. This is the definition and this is the schedule. We also have the same for infiltration. A load name and the schedule. You will recall in a previous exercise we created a microwave load.

That was to be applied to the closed office. You will note that there is no microwave load on the office so we will have to drag that into this space type definition.

Browse to electrical equipment definitions. Locate the microwave in the Electric Load Definitions. It appears that we may have deleted our microwave load definition.

Or, we purged it in the previous exercise. Let us add that back into our loads. Select the loads tab, electrical equipment definitions, copy this, rename it. Next, go back to the space types tab. Select loads, scroll down to closed office, go to my model, electric equipment definitions.

Drag and drop the microwave into the closed office space type. You will note that the microwave has been automatically assigned the fire station equipment schedule. We need to change this to the microwave schedule that we created.

Go to my model and browse down to the rule set schedules. Look for the microwave schedule that we created. Drag and drop that next to the microwave load that we installed. Now the microwave load and schedule has been applied to that space type. You can see this has a multiplier. This is used for fine-tuning a model without having to change loads or schedules. If we discover that the microwave is actually being used half as much as what what we thought, we can change this value.

We will not do that here. You will note that the default values are green and any overridden values have been changed to black.

That is how you add loads and loads schedules to a space type. There is a filter button up here. For very large projects that comes in handy. For example if we wanted to just look at occupancy loads we can filter by people.

For lighting loads, we can filter by lights. Up at the top, the Measures Tag tab also is comes in handy for advanced energy modeling. As discussed, these are keywords that energy efficiency measure EEM programs use to change the energy model.

They are use it to see how it affects energy use of the building. The Custom Tab, I believe, is used for custom programming. I will briefly discuss how to create a new space type. Rename the space type to what you would like.

We will call this Workshop. Next, apply a construction set. Apply a schedule set. Apply a specific outdoor air. We will just copy or we can select a different one. Let's go to the library tab, specification outdoor air. We will just do mechanical room ventilation. Look for an infiltration design flow rate. Look for mechanical room How about Utility. Next, go to the loads tab. Locate your new space type, Workshop. Drag and drop loads into the space. This will be a Machinery room so we won't have a people definition.

We will do lights definition, storage and electrical equipment utility. Finally, we want to assign an electrical equipment schedule. To do that, go to my model, rule set schedules.

We will just say that the electrical equipment is always on. That is how you create a space type. To delete it, simply push the X button at the bottom. Click the checkbox and then push the X button. In a previous video, we created our building geometry. In this video, we will revisit the geometry tab and discuss additional features for viewing and editing the 3D model with FloorspaceJS.

Next, we will go to the geometry tab. At the first tab is 3D view, in geometry. This allows you to inspect the building model. Using the right mouse button you can pan the model across the screen Using the middle mouse button you can zoom in and out. Using the left mouse button you can rotate the model.

Over here are some additional controls. Changing the orthographic control changes the perspective of the model. This can be useful for selecting specific items based on a view.

Let us do the X view. You can see that without orthographic turned on, it shows a more perspective view. Next, there's some additional functions that act as filters or rendering. Right now we have it rendered as a surface type. You can see that the roof is colored a beige color. The walls are brown. Glazing and glazed glass doors are a more transparent color. The overhead doors are a dark brown color.

The ground floor is a gray color. Right now all of our surfaces are oriented properly. Let's get rid of walls. You can see that all of the outside surfaces are gray and all of the inside surfaces are red. If one of our surfaces was accidentally flipped, we would see it show up as red on the outside. That tells us that we need to correct its orientation in the geometry editor. Next, if we go to boundary rendering, this shows you how the energy model will be rendering. How the energy model will treat the surface.

Most of the blue is an exterior surface. Let us get rid of walls. Again, you can see that the interior surfaces are green. Let us get rid of roof. The interior walls are green. The interior floor is brown. I'm sorry the the ground floor is brown. All of the exterior wind exposed and sun exposed surfaces are blue.

Next, we'll look at render by construction. This tells you what type of construction it is. The purple are windows. The teal color is an opaque door. We also have glazed glass doors which are colored white. The exterior walls are a grayish Brown. The roof is colored pink and the ground floor is colored Olive. This will help you tell if you have additional construction materials located throughout the building that have been specifically assigned to specific spaces.

Next, let's look at render by thermal zone. This shows you all of the thermal zones located in the building. These these are the thermal zones that we assigned in the very first lesson. You can also see if there are different spaces, but there they might be combined into a single thermal zone.

Next, we will look at space types. This renders by space type. All of our plenums are a dark red color. We also have storage space, office space, locker, restroom spaces, and a community space. We can also render by a building story. However, for this example we only have one building story so it only shows one color, green. As discussed, you can also apply filters such that you can't see certain surfaces or sub-surfaces.

If we wanted to get rid of the roof we would uncheck the roof so we can see inside the building. Let us switch back to render by surface type.

Likewise, you can remove the doors and windows. If you do have shading objects in this file, you can hide them. But we don't have that in this model.

That will be a for a future lesson. If you have partitions located inside the model, for example office cubicles, those would show up here and you can hide those. We don't have those in this model. Finally, you can click this button to show as a wire wireframe.

Although I don't know how to use this. Next, let's go to the editor tab. We will discuss some of the additional functions of FloorspaceJS. Let us do an example for this space here. It is actually comprised of two separate spaces but we originally just created one large storage space. Let us split this into two. Next, we want to draw in a new space. We will use the polygon tool this time. Click to begin the polygon, click, click, click, and to complete the polygon click at the very first spot.

Next, create the tools room. Messed up. Let us use the undo button. Create one more space. Next, we will have to rename these and add in the plenums. Space Okay, it appears that the program is moving slowly, or it's even frozen. We can wait for it or we can try a different approach. Let us go ahead and reopen this.

Go back to the geometry tab. You can see that none of the changes were changed on this. Click Save and go to the file folder of the project that you're working on. Go to the open studio folder where all of the project files are located. Find the floorplan JSON file. Open it in a text editor. Save it. Then we will open this floorspace JS file using an online version of floorspace JS. To do that, open a web browser. Browse to unmethours. This will be a good exercise to show you how to troubleshoot problems.

If you have questions, it has probably already been answered on unmethours. Select this topic. You can read through it. It uses Javascript, so any web browser can open it. We will open this link to FloorspaceJS and we will open our file. Browse to the project folder where the file is located.

Now we can see our floor plan. Delete this plenum. I'll show you additional functions that FloorspaceJS has. We are editing these two storage rooms, so let's use the eraser this time. I'll show you how the eraser works. Simple as that. It erases the space. Then, we will go back to the polygon tool Then we will go to the polygon tool to create a new storage room. The duplicate tool is very powerful. It allows you to duplicate all of these items that were filled in before, so that you do not have to refill those in.

We have now split this room into two. Next, go to assignments. Let us see. We will have to create a new thermal zone for this new space. Let us go back to floor plan now. I'll show you some additional functionality that FloorspaceJS has.

If you wanted to create another story for the building, simply use the duplicate tool. It places the next story right above the first story. You can edit the attributes of the stories using the expand button. An additional function that FloorspaceJS has: this fill tool. If you have a story above another story, you can use the fill tool to simply copy the previous space below up to the space above. This Apparatus Bay, on Story 1. If we just click the fill tool, and click, it creates another Apparatus Bay above, in Story 2.

We can expand this and look at the space. Excuse me. It just creates a space. You will have to go through and fill in space type, construction set, thermal zones. For this project, we won't be using a second story, so we will just go ahead and delete story. Once you're done editing the floor plan, we can go up to the top and click Save Floorplan. Click download. This will download into your downloads folder. Next, go back to the project folder where your OpenStudio files and.

Go to your downloads folder. Cut and paste this. We will want to replace the file. Next, go back to OpenStudio and reload the project. Go back to geometry tab. Go back to editor. You can see that these are the spaces that we created using the web browser version of FloorspaceJS. We will just do a preview.

This is good to hit. This button I am not sure what it does, but it refreshes the 3D model. You can see that those spaces have been added. We will click close.

Merge with current OSM. Click OK. Now we can go back to the 3D view and we can see that those spaces have been edited.

The last task: go to spaces tab. We will rename those spaces that we created. This one was This is plenum. Go to thermal zones tab. You will see that FloorspaceJS created a bunch of extra thermal zones. I'm not sure why.

It is a glitch. You can simply get rid of those by doing purge unused objects. Finally, we will save the OpenStudio file. Review our geometry. You can see that the floor plan has been edited. In this video, we will discuss how to orient our building relative to North. We will set defaults for space, constructions, and schedules. We will add exterior lighting. We will also briefly discuss adding stories to the building and adding shading elements.

The next tab is the facilities tab. Go to the left and select the facilities tab. On this tab you can change the building name. We will call this Rural Fire Station. Next, you can see there are measures tags, just like we discussed previously. Next, you can see the north axis as set at 0. Going back to the geometry tab, we can see that the north axis is currently set on this green axis line. To take advantage of this integration, you will need to follow the steps outlined here to request a BCL key.
