Here, the basics of using the Design Development Wizard in eQuest are discussed.

After becoming familiar with the schematic design wizard, the next step is to become familiar with the design development wizard, which takes it up a notch. Lets get started, select the wizard and pick design development wizard.

Initially the project and site data screen will pop up and there are only 7 screens to go through. In fact it will proabably be less since you won't go through all the screens. There isn't much new here compared to the Schematic Design wizard. We're not going to enter any custom data in the example, so as to not bore you and get through it quickly.

After clicking continue on the last screen of the wizard setup, you are taken to the Project Navigator. Here we can launch a number of different wizards or different screen sets. So we have a shell and a system, which you can edit or create new instances of. So we can now have multiple shells. We just finished the project site utility so we can look at the building shell utiltiy. Either ed the exitsing one or crewate a new one. Here we have the shell name. You will see most things are almost exactly similar to the SD wizard. There is a shell multiplier, daylighting controls, and more.

We'll continue to until we see a relatively new screen, screen 12. Here we can define building operation schedule per day.

Screen 13: Pretty identical to what we saw in the SD wizard. Our occupancy profile by season can be edited. We can select office equipement profile and it will show the default profile, which can be alerted, or we can take the existing project and essentially stretch it. So for instance if there was an addtioinal two hours that this was one, on both sides we can enter minus two and plus two. This stretches the exisiting schedule without changing the general shape. One of the nicest features of the design development wizard is the custom zoning screen. Here we can click to our zones, or rather our zone groups, and we can even assign systems to each one of these. In this case we only have one system defined, but if we had more defined, we could break them. Furthermore, we could delete a zone group and make a new zone gorup.(3:15)

Here we're going to create a new zone group, called dummy zone. So since all the zones are defined, we're going to have to pick out a dummy zone somewhere. Lets take it from one of the perimeter zones, and here we can click on the zone, assign zone to other group and select dummy zone. So now we created a new zone group and we assign a single zone to that group, which we could assign to a new system, or change the parameters. We can even adjust the zone group details, in this case just adding exhaust fans.

Continuing on, we define the types of heat in the spaces and the types of energy consumed in the exterior. In other words energy consumed, but not affecting the building HVAC.

Screen 16 is pretty similar to the SD wizard. Here we define, the watts per square footage of lighting in each of our area types. Please note that eQUEST does make pretty solid defaults out of these values.

The next few screens don't need much elaboration. As we get towards the end we can define at screen 25, we can define our exterior lighting load and we can establish the profiles month to month, which is pretty cool feature, but somewhat time consuming. Finally, we can adjust the domestic hot water profile as well.

Once we're done with the shell information, we can return to the navigator. Once back in the navigator, we could edit the selected system. Here it's important to note we're only going to see one system at a time, since all systems are listed individually. 5;52, So here we select the cooling sources and heating source. The defaults are DX Coils and Furnace respectively. Lets say we're going to have chilled water coils and hot water coils. This will give us an additional field for the hot water source and it will also dynamically change the system types available. For instance, we wanted to select a chiller with hydronic reheat. We can that and we can give it one system per shell, per zone, per floor and so on. So as we continue, the proper screens will be enabled.

We can define the fan operating schedules day by day, screen 6, and also weather or not there's baseboard heating and economizer which defaults to a dry bulb economizer with a 70 degree Fahrenheit shutoff. Finally we can define outdoor air reset, because we have a VAV system. Please note that based on the system type that you select, more options or less options will be available. Now that we have defined a system that requires hydronic heating and hot water heating, we have the chilled water plant equipment available and the hot water plant equipment available. Please not that there is also water source heat pump and ground source heat pump plants available, and we'll discuss those in another lesson. For now it will suffice to say that these fields will only be enabled when we select the corresponding system type.(7:45)

This is a great feature in eQUEST because it prevents you from doing uncessary work. SO in this case we can select the chilled water plant eaqupment, and notice there's only a few screens, but we can select the pump system, again please not that in the SD wizard and the DD wizard, we can only select primary loops. We can select the pump head and the flow to size the pumps. We can also define the chiller types and chiller efficiencies. We are still limited to two cihller types, but multiple chillers of each type. An interesting feature here is that there's an estimated chilled water load based on the size of the building, the size factor, the number os quare feet per ton. So it tells us an approximation of what sized chiller to expect so that we can select a reasonable size. Here we can schedule the chiller (8:45), which is a pretty striaght forward process. If we go to the hot water screen, the fileds re paretty ssimilar and theory is about th same, however there are two screens in stead of three. The last screen like chiller, simply schedules the equpment. We can return to the navigator and edit the domestic hot water equipment where you can define the hot water usage, storage tank capacity, losses, all factors that you would expect to define when modeling domestic hot water. So having defined that we can return to the navigator. Click the finish button, and eQUEST will run the BDL file and will load in the detailed view. Here everything is the same as we saw in the schematic design wizard tutorial.

Next up, using the EEM wizard.
