Step 1: In the following picture (Figure 1.1) illustrates the "Number of Rooms" field which is the number of rooms you wish to calculate Heat (Loss) Gain. The Initial Value is zero the value must be greater than zero to continue to the next step. The "Name of Residence" field has the default value is "House" which you may rename which will appear in your results.

The average summer temperature may vary in different states or regions. The heating design temperature (Heat Loss) is the average winter temperature. This is optional and only will be calculated if you check the "Heating" checkbox.

Step 2: The following screen (Figure 2.1) shows the "Name of Room" field the default value is the number of the room. You may rename this field to customize your selection. The "People" field is the number of people that would normally produce a load on the room. The "Area of Room" field is a required field and cannot be less than zero. This is the sqaure footage of the room you are configuring.

The next part of this screen is the Total Exposed Wall Calculation (Figure 2.2) which has three fields. The first field is Ceiling "Height" of the room, the second field is "Length" of Exposed Wall. The "Height" field is remembered providing you have more than one room. The "Length" field is the length of total exposed wall in the room. The button "x" is the multiply button which loads the product into the "Area" field automatically. You may also enter the area of exposed wall directly into the "Area" field, which overides the mulitply butto

In (Figure 2.4) the make-up air conditions and CFM field are illustrated. There are three choices Not Applicable or no make-up air entered into the heat (loss) gain or Infiltration which is a factor that adjusts the load to compensate for drafts. The third choice is if your home contains any mechanical ventilation.* In this case you must enter a number greater than zero for the value of CFM in the field provided.
