When reviewing an GUID-2043E09F-40E5-4155-AE28-134F62E54F54.htm#WS73099CC142F487552C60378B128B24194AD655E in the Results and Compare dialog, this chart shows the cumulative heating loads on the analyzed model for each month.

Note: This chart does not represent the peak heating load used for sizing of heating equipment. The chart also does not represent heating loads caused by ventilation air, which can have a significant impact in densely occupied buildings.

Example: In the sample chart above, the largest negative value for January is Window Conduction. Therefore, heat loss from conduction through windows represents the largest single monthly demand for heat in January. However, Miscellaneous Equipment (which includes plug loads, computers, office equipment, and so on) reduces the demand for heat.

To reduce the heating load on the project, use the graph to identify the critical component. In this example, windows cause the greatest amount of heat loss. Roofs and walls result in a significantly smaller amount of heat loss. Therefore, you should focus on the windows and reduce their GUID-D44E4744-B5DF-467A-A4A1-1FBC4A00E0D9.htm#WS1A9193826455F5FF11D4ED1B128F2317A0815F6 to reduce the heating load.
