Setting Project and Zone Information
|Top Previous Next|
To set the project information, go to
DM HVAC Building Definition Project Info
The Project Information dialog box will open. At the top, type "Tutorial" in the Project Name field.
Note that the city was selected when the project was created (see Starting a New Project for a review). The city may be changed at any time during the project using the Select City button in the Project Information dialog box.
Also while you are in the Project Information dialog box, select the check boxes next to June and August as shown below. The months that are checked in this dialog box are the ones that will be used when the loads are calculated. Selecting more months allows you to include non-summer peaks in your loads. For example, it is common in southern latitudes to have room loads with lots of south facing glass that peak in the winter months. However, selecting more months increases the amount of time it takes to calculate the load. You will need to use your judgment to determine when to calculate loads for more than the typical summer months.
When your Project Information dialog box matches the one shown below, press OK.
To set the zone information, go to
DM HVAC Building Definition Zones Zone List
The Zones dialog will open as shown below.
Next, you will create two more zones. Press the New button. The New dialog will open as shown below.
In the New dialog box, type "Z1" as the New Zone Name and press OK. You have now created a new zone in the database. Repeat this process to create another zone, called Z2, in the database. At this point, there are three zones in the database; the default or main zone, Z1, and Z2.
It is now important to set which rooms are in which zone and how the zones are related to each other. This is done using the Zone Tree. To do this, go to
DM HVAC Building Definition Zones Zone Tree
The Zones and Rooms dialog box will open as shown below.
Note that when Zones Z1 and Z2 were created, they were automatically placed under Zone Default, which is where we want them. However, we also want the offices and storage room (Rooms 103 thru 107) under Zone Z1 and the conference and lobby (Rooms 101 and 102) under Zone Z2, which they currently are not. To put them in the correct location, click and drag the room the way you would rearrange folders in a Windows Explorer window. When your zone tree matches the one shown below, press OK.
The next step is to view and print the load calculations.
