[00:00:00] In the last video, we looked into the internal loads in our model. In this video, we will walk through the spaces. We’re going to look at two pages in the OpenStudio application. First of all, the Space Types page, and secondly, the Spaces page. Spaces page can take a little moment to load. Sometimes it does seem a little bit slow but that is because it’s loading quite a lot of information. As you can see here, there is a grid view of the spaces in the building and for each row, we have information about each space. Now there are approximately 30-odd spaces in the building, and as you can see here on the grid view, there’s quite a lot of information against each space. That allows us to do some filtering. So here we go through and assign different space types to the spaces. We’ll be able to filter by building story, perhaps by thermal zone, even by space type.
[00:01:16] So I’m just going to get the filters back to Show All. Let’s go back to the space types and have a look at what sort of information we can manage and create here on the Space Type page. So Space Types is a definition that allows us to bring together different sorts of information that defines how the spaces will operate from an energy consumption point of view. There is a few different areas to look into on the Space Types here. The General view tries to give you as much information as it can. On the Loads view, we can see for each space type, we’ve got different loads, a multiplier for each except for the infiltration. There’s also a schedule that defines how the magnitude of the load varies across the day, across the week, and across the year. There’s also measure tags and a Custom view.
[00:02:36] The measure tags we won’t go into, and to give you a sense of how to use the Custom view, if you want to select a couple of columns to compare against each other, the way you would do that is to just click on the top of that column. See it’s highlighted blue. I click again to clear it. So let’s say we want to compare the load name and the definition for example. I click on the top of those columns, they become highlighted in blue, and if I click over the Custom tab, I can then see those columns against each other.
[00:03:12] Let’s go back to the General view and just have a quick look at the space types we have in our model. These space types were brought in at the new wizard stage right back at the start of the workflow, so these are predefined space types that come with our construction set and space types wizard. So against the office break room space type, we have a schedule set, an outdoor air specification, and infiltration specification. We’ve also got some loads, some for people, lights, equipment, and how those vary as I said before. So that Space Type page is set up and good to go, really. It’s got all the information that we need on it and not a lot of work to do there.
[00:04:01] The thing we need to do next is to ensure that the spaces in the building have the correct space type assigned to them. The way to do that is to go to the Spaces page and what we’re going to now do is work our way down this list and ensure that the space type is correct for the space. So I might make use of a custom view here. All I really need to see is the story and the space type so we’ll click over to Custom. Let’s look at this one story at a time. Now that admin office, I want that to be an open office type. Cafeteria, obviously I don’t want that to be an open office type so I’m going to go to the Library and Space Types view, just go to my Model. So I’m looking for some suitable space type to reassign to that cafeteria. For want of anything better, I’m going to reassign that as a vending space. Now for the conference. Let’s give that an IT room. Corridor, we should have a corridor type.
[00:05:37] As you can see, I’m just dragging the space type and dropping it in the space type drop area against the row. The corridor lobby gets a corridor type. And now that files room should get a storage type. Meeting can have the office/IT room. I should have a closed office for the office one, a nine-to-one twelve. And a reception area if possible. Let’s give that a lobby. I’ve got a few more to go here. The next one is a restroom. Now I’ve got a couple of stairs. These vestibules, I’ll give those a lobby type. And that’s it for level one. I’ll now do level two.
[00:08:42] And that is that for level two. So for each space in the building, we’ve now assigned a space type to it. Now that’s going to take care of the internal loads and schedules for those space types. As we set the constructions previously at the facility level as well as the story level, we won’t need to dig too deeply into the construction settings. Now just for interest, I’m going to show you the Loads tab. What you’ll note here is that the grid view shows no information. Now you might find that a little bit counterintuitive because we have set up internal loads. I believe that the way that this works with the set inheritance in OpenStudio is that we’ve assigned those loads at the space type level so they don’t necessarily appear in this grid view on the loads. If you were to assign loads at this tab that we’re looking at now, that would be a low level in the hierarchy and that would override anything at the higher level where we have assigned loads.
[00:10:05] So don’t be too surprised if you don’t see anything here, and that’s because we’ve assigned loads at another level. Let’s have a look at the surfaces level. Now the Surfaces tab shows each surface for each space. So here we see the admin office and that’s got all the walls and floors for that space. Now, just to be different, OpenStudio does show the information at this level on this tab. And we can see the construction that is applied to each surface in this grid view. While we’re here, the check that needs to be done is to look at every surface in this model and ensure that it has a construction applied to it. If you don’t have a construction applied to a surface, your EnergyPlus simulation will fail. So let’s go through this grid view and make sure that every surface has a construction applied.
[00:11:12] Just scrolling down the list, we look against each surface and into this column here where we see the surface has a construction applied. And so far, there are no blanks. Here you’ll note the air walls and we assigned those to the corridor when we were working in the SketchUp stage. And just working my way through the building. I haven’t seen any blank yet, which is what we expect and what we are checking. Interestingly here is the interior wall on story two and that was the variation we made to level two where we demonstrated how the set inheritance works and how to make a variation on your construction set for a particular story of your building. And just going through the list just scrolling down to the bottom here, the visual check is so far so good and we have no surfaces with missing construction. So that’s our task completed there on the Spaces page. Let’s save a checkpoint. This is stage seven. Save Video7.
[00:12:47] So in video, we have gone through the Space Types page and the Spaces page and the important things to do in this part of the workflow is to ensure that every space in the building has a space type assigned correctly and that every surface of every space has a construction applied to it. In the next video, we will look at thermal zones and then begin working with a detailed air track page.
