Hi. This is the last section of today's webinar. We'll to talk more on this space tab. Well if you remember, we have finished many of things already. For example, you know from where you get all those properties related to internal loads, surfaces, and sub surfaces. Let's go through each and every tab one by one. Basically, in OpenStudio, the space is the root element for form and fabric. This space contains some kind of form as well as fabric, which you have assigned here, already, okay. And, a lot of properties are like loads, internal loads, surfaces, the angular properties. They get, they can be inherited from the space type method. You just assign the space type, and all the properties related to internal loads, schedules, installation, will already be there, okay. You have to provide some information like, hey, story, like, as you remember, like, what a story does. You can provide any story. In case you want to change it, go to my model, go in stories. Let me just find it.

Can you see it, here. Well, let me just see it properly. Well, unfortunately I don't see it. Actually, it's here, sorry. We have two stories. If you want to assign a different kind of schedule set, just change the story. And then, thermal zones. I won't, if it's me I won't change thermal zones here. Because, we have assigned these thermal zones in SketchUp already. In case you want to delete any particular space, you can also delete it here. But, I won't recommend it. Again, because then you will have lot of problems associated with surface matching. Don't do this, okay. You can change space types. I already mentioned how it works. For example, if I want to change this space type for this floor one conference 3. Go in my model, again. Space types, and look for any space type that you want to assign. Maybe, let's say, you want to assign a lobby space type this time to this space, okay. Now, it has a new space type.

Do you want to assign the construction set at directly space? Well, you can do that if you have, let's say, a conference room, which is totally an isolated body. And, it has a different kind of construction set. You can assign it, here. Schedule set, if you remember, we assigned a new schedule set for just this conference room 104. It overwrites the information that has been provided through this space type method. Well, there is no space type. It is basically going to use this schedule set, okay. And, let's say if you want to remove some spaces from the total floor area calculation. You can just uncheck any of these spaces here, okay. I don't like to play around a lot with my spaces because I have created my geometry in SketchUp. And, without visualizing what is happening here, I don't want to create anything. Very important guys. Just be very careful when you delete something here, okay. I'm not going to do this exercise here to bring a new schedule set or space type. We already have done it in my previous videos.

For example, if you want to change, see how the schedule, how can you change the schedules. Look for my schedule video. Same thing with space types, okay. Go to air flow, now. You can see, we have all that air flow information that we assign at space type level. We have object, air objects, I'm sorry. Outdoor air objects, the infiltration information, everything is already there, okay. Go to loads, now. If you remember we assigned the new loads for this conference 104 room. We created everything from scratch. That's in the load video. There is a video for internal loads, look into that.

You can change these schedules. All the information is in my model. You can create something new in either schedules or internal loads and can assign them here directly. Let's say, if you want to bring additional like, pianos or like, let's say, do you want to bring one more fish tank. Well, you can just use a multiplier, here. Just make it two, and it means the, this load is twice now, okay. Same thing with piano. Let's say, for your two pianos in the conference room. Let's just change it here, okay. It's very easy, here. Like you can always use multiplier. It's very effective. What else. You can always change the names. In case you need to delete something, let's say, I want to be this fish tank. I can check it, here, and delete it. I can copy it, I can duplicate it, I can do so many things.

Let's say, you have one fish tank, which has totally separate schedule. I can, there two fish tanks. I can make a copy of it. Rename it to fish tank load underscore 2. And, change the schedule. Instead of 24 hours, I can go to my model, go to rule set schedules. Change it to, let's say, a conference 104 people schedule. Somehow, designers, they like, get to make this fish tank work as per the people schedule, okay. Save it, now. And, you can run this simulation, okay. Go to surfaces, now. It's gonna take some time, I know. Again, for each and every surface, you need to provide the name, surface type, construction, outside boundary condition, exposure. I don't like to play around with this thing. Again, as I mentioned, I made all those changes already in SketchUp. And, I know there is no error there. Without visualizing anything, I don't like to make changes. But, you know how it works. In case there’s just, green in them, you can do it easily.

You can change the surface type. Well, I won't do it, you can assign a new construction type. Let's say, for, for this roof, here, for conference 104. I want to bring a new construction, okay. Go to constructions. Let's say, I want to assign this roof installation. Just update it, here. This texture is black in color. It means the property has not been inherited from some upper level. I can up like, use this like, shortcut method. For example, I want to assign this exact, the same construction set, I'm sorry, the construction. Let's say, here, in, I'm sorry. Let's just like, you know, play something else. If I want to assign, let's say, this construction set, here, this exterior room, even at this wall. Let's just, like, you know, do some experiments. I can select it here, in this second column. Like, I want to make changes here, okay.

And now, click on this, the construction that you want to apply. Hit apply to selected, here. It's being highlighted, now. You can see, click on it, okay. You can see this, there's a new construction. Although, when you run the simulation, the model, or the engine won't like it. I'm going to change it back to the existing one, which is exterior wall construction, here, okay. And, save the model, again. Or, you can just delete everything, here. And, it will bring the default one, which was the green one. Again, just delete this one, as well. Select this black wall construction, and delete it, here. And see what happens, okay. Now, we have the default green one, which has been inherited from the building level, okay. Again, as I mentioned, don't make any changes. It's not advisable. Like, even as a,  as an OpenStudio user, which has some experience, I don't like to make changes, okay. Just save the model, right now.

Or, actually, we can just make a new copy before we make any crazy changes. It's always advisable to make a new copy. Let's just save it. Save that space, and save it, And, same thing, again, with subsurface. You can go to subsurface section. Again, you can provide the construction set. It's all double pane for now. You can change the subsurface type. Let's say, from fixed window to operable window. You can totally do this. You can rename it. But, I won't suggest you to select it and delete it, unless, you know what you're doing, okay. Let's not make those kinds of changes. You can always fall in some crazy trouble, okay. You can always edit the geometry, by using the Notepad++. Just open the OSM file in Notepad++ and make changes. But again, it's very dangerous. I wouldn’t suggest you to use it, unless you get some good experience with the tool, all right.

What else. You can do lot more things, here. I can explain to you how to make changes in installation on envelope by using the OpenStudio measure method. We are going to run some amazing measures in our next webinar. But, for now, let's just a work, here. Next thing is interior partitions. You can create some interior partitions. We don't have anything right now. We can create them in SketchUp. Same way you just hide the roof of one space, and use the internal partition tool. Bring it in the space, and create it, okay. It's, again, very easy. Something, what you create for, what you do for creating a wall or window. Well, when you create some kind of interior partition in space, it always comes as the thermal mass. It will have some kind of construction property. It will have some kind of, thermal lag kind of thing. Again, like, you know, if you have a lot of furniture, or interior partition in space, and you think it's gonna affect your thermal lag or something, maybe you should need to model that. And, most of my projects, I would say almost 99% of my projects, I haven't used interior partitions. But, again, it's always good to know how it works, okay. They always work as thermal mass, okay. Like, you know, they will, when you bring some kind of interior partition surface, they will convert it, the software will convert into a like, solid mass object, okay. That's how the simulation works.

And, the last one is shading, okay. Again, these shades are always like, you know, like they need to be created in SketchUp, or, Rhino, if you use honeybee. I don't suggest you to make any changes here, again. Same thing I don't want to delete something without visualizing it. But, you can always void some kind of transmittance, or schedule, or, like, construction properties. Again. there are two ways to do it. You can either do it in space, okay. For example, if there's just one building shade here, which is on lobby, this one, you can make changes, here. Provide some kind of construction properties. Let's say, if I want to make it of same material, what my windows are. I can go to construction, where is construction, I know it's a long list, sometimes it's a bit difficult to find things you want. But again, it gets easier with your experience. I created some transmittance schedule, which is wrong. I was supposed to bring it, here.

Let's go to my models, again. Bring this wall construction, and assign it, here. My shading devices are made of glass, now. You can provide some kind of transmittance schedule. You can do so many things, here. These are building shades. If you go to facility, and in shading here, these are all side shades. The shades which won't move with your project, okay. Again, it's a bit confusing, there's a kind of bug, here. Like, for example, you can see it's like, it says space, here. Well, technically these shading surfaces were supposed to be here, in the space tab. Which work fine, as long as you provide some information, it's all right. I would say, save this model. And, you can see like, we provided this exterior window material with the shade in space tab, which is reflected here, as well. It's all right, like, you know, it won't make any huge impact. You can save the model. And, whenever you want, you can just run the simulation, okay. I'm going to run on it. And, meanwhile, I'll give you some more feedback.

Looks like we have done a lot more than our first class. It's a lot of information, a lot of new information. Please practice whatever we have done so far. I know we haven't run any HVAC related information through our model. But, next class we’ll create some more information in our project. We will use OpenStudio measures. That's going to be a very important class. And then, we're going to, we are going to work on some zone, zonal HVAC equipment, okay. Thanks a lot everyone, for joining this session. I hope you learned some new stuff, okay. And, please don't hesitate to write us down. You know our email IDs. If you want to contact me directly, that's my personal email ID. And, that's, that is my, that is our company's email ID. Bob basically is going to reply you back when you write it down here, okay. Thanks a lot everyone. I hope you enjoyed this session. Take care, bye.
