Rooms

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.

•	Air Changes / Hour: The Minimum Supply Air is set based upon the number of air changes per hour.

•	CFM / Person: The Minimum Supply Air is set based upon the number of people.

•	CFM / SF: The Minimum Supply Air is set based upon the area of the room.

•	CFM: The Minimum Supply Air is set to a specific airflow value.

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.

Watts / SF: Select this option to set the lighting load based upon the room area.

Watts / SF: Select this option to set the equipment load based upon the room area.

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:

•	Air Changes / Hour: The ventilation rate is set based upon the number of air changes per hour.

•	CFM / Person: The ventilation rate is set based upon the number of people.

•	CFM / SF: The ventilation rate is set based upon the area of the room.

•	CFM: The ventilation rate is set to a specific airflow value.

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.

•	Same as Cooling: The heating ventilation rate is the same as Cooling 1.

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.

•	Same as Cooling: The heating ventilation rate is the same as Cooling 2.

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:

•	Air Changes / Hour: The infiltration rate is set based upon the number of air changes per hour.

•	CFM / SF of Wall: The infiltration rate is set based upon the area of the walls in the room that are set to Heat Transfer and Solar Gain (Wall). See the Query Wall section for more information about this setting.

•	CFM: The infiltration rate is set to a specific airflow value.

•	Same as Cooling: The heating infiltration rate is the same as Cooling.

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.

•	Custom: The load for each person is entered manually using the Sensible Btu/h / Person and Latent Btu/h / Person fields.

•	Seated at theater: Sensible load is 225 Btu/h per person, latent load is 105 Btu/h per person.

•	Seated at theater, night: Sensible load is 245 Btu/h per person, latent load is 105 Btu/h per person.

•	Seated, very light work: Sensible load is 245 Btu/h per person, latent load is 155 Btu/h per person.

•	Moderate office work: Sensible load is 250 Btu/h per person, latent load is 200 Btu/h per person.

•	Standing: Sensible load is 250 Btu/h per person, latent load is 250 Btu/h per person.

•	Eating (including food): Sensible load is 275 Btu/h per person, latent load is 275 Btu/h per person. Includes 30 Btu/h sensible and 30 Btu/h latent for food per person.

•	Light bench work: Sensible load is 275 Btu/h per person, latent load is 475 Btu/h per person.

•	Moderate dance: Sensible load is 305 Btu/h per person, latent load is 545 Btu/h per person.

•	Walking; light machine work: Sensible load is 375 Btu/h per person, latent load is 625 Btu/h per person.

•	Bowling; heavy work: Sensible load is 580 Btu/h per person, latent load is 870 Btu/h per person.

•	Heavy machine work; lifting: Sensible load is 635 Btu/h per person, latent load is 965 Btu/h per person.

•	Athletics: Sensible load is 710 Btu/h per person, latent load is 1090 Btu/h per person.

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.
