[00:00:00] In our last video, we started modeling in the OpenStudio application.  In this video, we will continue in the OpenStudio application, this time moving onto the Schedules page.  We will show how to create and edit schedules, how to create a schedule set.  Let’s go ahead and open up a OpenStudio window.  Find your way to the file that we last saved and we’ll open Video3.  Let’s move to the Schedules page.  First question that will jump out at you at this point most likely is, “What is a schedule set?”  So here we see the 90.1-2010 office breakroom schedule set is highlighted and in the main window, we can see this defines a number of default schedules for various internal gains and how those gains vary: the hours of operation, the number of people along the top, the people activity levels, lighting levels, equipment, infiltration levels.  Some of these are blank as well.

[00:01:16] So our schedule set is really nothing too confusing; it’s just basically a collection of schedules that are defined for a sort of space type purpose.  The next tab on the Schedules page is the Schedules tab.  This gives us access to create and edit individual schedules.  So while we’re here, let’s create a few new schedules as a way of demonstrating what to do and how to do it on this page.  Use the + symbol here to create a new schedule.  We’re going to choose the fraction type.  First of all, we’ll rename it.  This schedule is just going to be a very simple one, demonstrating the idea of something being always on.  Here you see the lower limit is zero and the upper limit is one, and we’re just going to drag that value bar to be one.  Now if I hover the mouse and it goes blue, I can enter a value and that now is set to be one.  You can see that that is continuous throughout the day.

[00:02:25] Now I you turn your eyes to the calendar view on the right hand side here, the blue indicates the default run period profile, and that is the same for every day of the month and all months of the year.  So all we’ve done here is create a new schedule, we’ve renamed that Always On, and we’ve given the schedule value one continuously throughout the year.  Let’s copy that with this blue x2 button and this one has been given the name Always On 1.  Let’s change that to Always Off.  And if you’re still with me, you’ll no doubt be one step ahead.  We’re just going to change that to zero, and this schedule now represents something that’s always off.

[00:03:12] Finally we’ll add one more type.  Let’s make this a schedule that represents how electric equipment might vary within a building.  So we’re going to use a fractional schedule again and we’ll call this Elec Equip.  This one’s going to have a bit more variation to it.  Let’s say the overnight value is down here at around 15%, and then during the working day, from around 7:00 to around 5:00, the equipment goes to fully on.  So let’s just pop into the 15-minute view here and we can see this vertical bar needs to be dragged over to 7:00.  And likewise, we’ll drag this one to 5:00.  So there we have a schedule that is at sort of 15% overnight and 100% during the day.  Now that, at the moment, is for all days during the year.  So let’s add another run period profile based on the default day schedule and let’s assign the weekends to this priority one.  And let’s say on the weekends, things stay at the 15% level.  Now we’ll double click on this vertical segment to delete it.  And I’ll just hover over the value bar and change that to be 15%.  So there we have a schedule, the electric equipment schedule, where it’s at one sort of run period profile during the working week and on the weekends, it’s sort of an after-hours condition where everything’s at that 15% standby level.

[00:05:03] So that’s the basic idea of how to add a new schedule.  You’ll notice here on the right hand side of the window here, we’ve got access to My Model, Library, and Edit.  And when we have a particular schedule selected, there is some information in the Edit view here that’s grayed out on this page so there’s not much you can do in terms of editing it.  There are access to schedule rules sets in the Library here and there’s nothing in My Model when you’re on this particular page.  But if we now go back to the Schedule Sets view, you can see under My Model that there’s new schedules that we added.  So we added Always On, Always Off, and Electric Equipment.

[00:05:51] So that’s a nice sort of introduction to how to create and edit schedules.  Next step you might want to understand at this point is how to create a new schedule set.  So with the schedule set selected here, it’s Add A New Schedule Set.  Rename this to My Schedule Set.  The idea here will be let’s add number of people, so we’ll grab the medium office building occupancy profile or schedule.  Let’s add some lighting.  So drop that office building lighting in here.  Let’s add some infiltration.  That’s the basic idea of how you can add schedules to schedule set.

[00:06:51] At the point, the schedules are set up.  We’ve got sufficient information here to progress into the next page.  The beauty of using the new wizard function that we ran when we were still in the Getting Started in SketchUp video is that it’s brought in a number of these schedule sets and schedules that fill in those sets, so there’s not a lot of work to do at this point and we’ve got the model populated with all the schedules that we’ll need in the next stage.  So let’s save our work at this point.  We’ll save this as Video4, which I’ve got here previously.  I’ll just override that.  Yes, I will replace that, thank you.  We now are ready to move on to the next video, and in the next video, we will start looking at the constructions in our energy model.
