Identify the space functions served for each of the HVAC system types entered by selecting the blue ‘Add Space’ button. Select from the use types that were previously identified in the Use Types section.

Enter the percentage(s) of areas served by the selected HVAC system type. If a Common Area was identified in the Use Types screen, enter the percentages of both the common area and the tenant areas served by the HVAC system. Add additional space functions to account for all of the use types served for each HVAC system.

The sum of the common area served by the entered HVAC systems must total 100 percent or the report will be identified as incomplete. The sum of the tenant area served by the entered HVAC systems should total 100 percent, but it is not required for submission.

The values entered for Space Functions Served will be used to calculate and populate the Principal HVAC Type field of the use types in the Use Types section. The HVAC system type with the highest percentage served for the total area of a selected use type will be displayed.

Example: 

20000 sq ft Office Use Type with 10% Common Area and 90% Tenant area

Packaged Terminal Heat Pump serves 100% of the Tenant area of the Office

Packaged Rooftop Air Conditioner serves 100% of the Common area of the Office

The total area served by the Packaged Terminal Heat Pump would be 18,000 sq ft, and the total area served by the Packaged Rooftop Air Conditioner would be 2,000, so Packaged Terminal Heat Pump will be displayed as the Principal HVAC Type for the office in the Use Types section.
