Include Cooling System

Includes the cooling system in the energy calculations

Primary System

Coverage

Displays the percentage of the building that is cooled by the primary cooling system based on whether there is a secondary system and what its coverage percentage is. If there is no secondary system, the primary system automatically covers 100%.

System

Select a cooling category, and then a cooling system. The system list can be modified; see Specifying System Sets.

Additional Air Change Rate

When an additional centralized ventilation system is installed, select this option to match the required demand, and specify the air change rate

Humidification/Dehumidification

When either humidification or dehumidification is part of the cooling system, select this option and select a system. The system list can be modified; see Specifying System Sets.

Secondary System

To include a secondary system, set a coverage value other than 0 (zero) percent

Coverage

Indicates the percentage of the building that is cooled by the secondary system

System

Select a secondary cooling category, and then a cooling system. The system list can be modified; see Specifying System Sets.

Include Cooling Distribution System

Includes the cooling distribution system in the energy calculations; the cooling system must already be included

System

Select a cooling distribution system. The system list can be modified; see Specifying System Sets.

Automatic Ductwork Length Estimation Based on Building Type and Size

Select this option to automatically estimate the distribution system’s ductwork length based on the building information

Manual Ductwork Length

Select this option to manually enter the duct length value
