SAE End-Use Data

The second component of the SAE module is accessed through Tools>SAE End-Use Data. The resulting dialog has four tabs for viewing different types of data. All of these tabs present a list of the SAE Sets in the Library or the selected folder. This allows the user to select the SAE Set and then view/modify the end-use data in the selected set.

The SAE End-Use Dialog has four tabs:

• Shares Tab. View and modify annual end-use share data.
• Efficiencies Tab. View and modify annual end-use efficiency data.
• Month Factors Tab . View and modify monthly end-use factors.
• Coincidence Tab. View and modify monthly coincidence parameters.

To open this dialog,

• Go to the SAE Sets Module.
• Select Tools>SAE End-Use Data… from the Tools menu.

This will open the SAE End-Use Data dialog. Select the tab to view, then select the named data object to view and the corresponding data will be shown in the expanded list tab.

Each tab on the SAE End-Use Data dialog contains a different type of data, providing time series and parametric values that are required to drive end-use energy intensity over time.

The end-use data types are as follows:

• Shares. Annual time series (historical and forecast) for share and/or saturation data for end uses and technologies.
• Efficiencies. Annual time series (historical and forecast) for Efficiency levels for end uses and technologies.
• Month Factors. Monthly multipliers for heating and cooling end uses and monthly allocation factors for other end uses and technologies.
• Coincidence. Monthly peak coincidence factors and monthly high-load-hour (HLH) factors for end uses and technologies other than other than Heating and Cooling.
• Peak Factors. 12 values for each end use are used to convert from average hourly energy for the month to load at the hour of the utility system peak.
• Monthly HLH Factors. 12 values for each end use used to allocate end use energy for the month between high load hours and low load hours.

Each of these types is managed separately. For example, each set of end-use shares is a separate named object in the system. Similarly, each set of month factors is a separate named object. This provides flexibility when end-use data of each type is assigned to an SAE Set. For example, a specific set of end-use efficiency values can be can be assigned to as many SAE Sets as desired, allowing the same set of efficiency trends to be used by multiple models in different areas.
