This section describes the commands used to create and modify rooms. The values that can be specified for rooms are listed below. Glass Zone Type: The floor covering type and partition type in the room as defined in Table 35B in the 1997 ASHRAE Fundamentals Handbook, page 28.49. See the ASHRAE Glass Zone, Roof, & Wall Types and Roof, Wall, and Glass Zone Type Tables articles in the knowledge base for more information. Include in Heating Load Calculation: Whether the room is included in the heating load calculations. Include in Cooling Load Calculation: Whether the room is included in the cooling load calculations. Minimum Supply Air: The minimum amount of supply air required for the room. If the supply air for the room based upon the heating or cooling load is less than this value, the required supply air volume for the room will be set to this value.
Design Temperatures Use the Design Temperatures section to set the goal temperatures and relative humidity for the room, and whether those values are based upon the zone the room occupies. Override Default Temperatures: Whether the heating and cooling temperatures are based upon the zone the room occupies. Check this box to enter values for the room type manually. Heating Temperature: The goal temperature used when heating the room. If Override Default Temperatures is unchecked, this field is disabled. Cooling Temperature: The goal temperature used when cooling the room. If Override Default Temperatures is unchecked, this field is disabled. Override Default Relative Humidity: Whether the relative humidity is based upon the zone the room occupies. Check this box to enter values for the room type manually. Relative Humidity (%): The goal relative humidity used when cooling the rooms in the zone. If Override Default Relative Humidity is unchecked, this field is disabled. Lighting Use the Lighting section to set the cooling load from lighting in the room. Watts / SF: Select this option to set the lighting load based upon the room area. Watts: Select this option to enter a specific value for the lighting load. Equipment Use the Equipment section to set the cooling load from equipment in the room. Watts / SF: Select this option to set the equipment load based upon the room area. Watts: Select this option to enter a specific value for the equipment load. Latent Gain: The latent equipment load in the room. Enter a specific value. Ventilation (OSA) Use the Ventilation section to set the ventilation rates for the room. All of the ventilation values use the same set of options for determining the ventilation rate:
Cooling 1: The ventilation rate for the room when cooling. Cooling 2: The second ventilation rate for the room when cooling. The total ventilation in the room when cooling is the sum of Cooling 1 and Cooling 2. Heating 1: The ventilation rate for the room when heating.
Heating 2: The second ventilation rate for the room when heating. The total ventilation in the room when heating is the sum of Heating 1 and Heating 2.
Infiltration Use the Infiltration section to set the infiltration rates for the room. All of the infiltration values use the same set of options for determining the infiltration rate:
Cooling: The infiltration rate for the room when cooling. Heating: The infiltration rate for the room when heating.
People Use the People section to set the number of people in the room. SF / Person: Select this option to set the number of people in the room based upon the room area. People: Select this option to enter a specific value for the number of people in the room. Activity Level: The sensible and latent load for each person in the room. Higher levels of activity result in higher loads. The values in this list are taken from 1997 ASHRAE Handbook, Fundamentals, Table 3, page 28.8.
Sensible Btu/h / Person: The sensible load for each person in the room. If Activity Level is set to Custom, this value can be entered manually. Latent Btu/h / Person: The latent load for each person in the room. If Activity Level is set to Custom, this value can be entered manually. |
