Zone

The zone name.

Group

The group name (assigned by the user or by the tool that created the model).

Zone multiplier, M

The number of zones with these conditions. The "TOTAL" row shows (where applicable) the sums over all zones counting with zone multipliers

Min temp

Minimal value of the mean air temperature in the zone.

Max temp

Maximal value of the mean air temperature in the zone.

Min op temp

Minimal value of the operative temperature at the position of the first occupant in the zone.

Max op temp

Maximal value of the operative temperature at the position of the first occupant in the zone.

Max heat supplied

Maximal value of the heating power (both sensible and latent) delivered to the zone from room units (both convective and radiative) as well as from mechanical and natural ventilation (including leaks and infiltration).

Room unit heat

Maximal value of the heating power delivered to the zone by the room units (both convective and radiative)

Max heat removed

Maximal value of the heat (both sensible and latent) removed from the zone by mechanical and natural ventilation (including leaks and infiltration) and by room units (both convective and radiative)..

Room unit cool

Maximal value of the heat (both sensible and latent) removed from the zone by room units (both convective and radiative). Condensation may occur in fan coils and ideal coolers, but is assumed not to occur on cooling surfaces in the room (a warning is issued if such condensation occurs).

Dry vent cool

Maximal value of the sensible heat removed by mechanical ventilation.

Max sup airflow

Maximal flow rate of mechanical supply air. Empty cell for zones without supply ventilation.

Max rtn airflow

Maximal flow rate of mechanical return air. Empty cell for zones without exhaust ventilation.

Max solar gain

Maximal net total solar energy gain from windows and openings (external and internal), including heat from absorbed solar radiation in the glazing and the frames (unless they are separate constructions). Net gain (or losses) of artificial light through windows and openings is also included.

Min rel hum

Minimal value of the relative humidity of the air in the zone.

Max rel hum

Maximal value of the relative humidity of the air in the zone.

Max CO2

Maximal value of the concentration of CO₂ in the zone.

Max PPD

Maximal value of percentage of people dissatisfied. The value is an average for all the people present at that time (in one or more groups). It is empty if there is no occupancy during the simulation period.

Max age of air

Maximum of 1/(Fresh air changes per hour). The age of the air is equal to the mean time the air is inside the building (includes the effect of AHU recirculation and air exchange between zones).

In use

The total time (during the simulated period) when the zone is in operation, i.e. the "in use" signal is positive (at least 0.01). The "in use" signal defaults to the maximum of all occupancy schedule signals with positive "Number of people in group". Schedule smoothing is not applied to these signals.

h of T_op>t

The total time (during the "in use" time) when the operative temperature at the position of the 1-st occupant is above the given limit. Two columns with different limits are shown. The limits may be selected in System parameters (parameters temp_h_low and temp_h_high).

Occ hours

The total number of occupancy hours, i.e. the integral of the actual number of occupants in the zone. For example, two persons present for one hour means two occupancy hours. The "TOTAL" row shows the sum of occupancy hours for all zones taking zone multipliers into account.

PDH

Hours of people dissatisfied, i.e. the integral of the PPD measure multiplied by the total number of present occupants. The "TOTAL" row shows the sum of PHD for all zones counting with zone multipliers. The total can be used to compare overall comfort between design alternatives.

Unmet hours (cooling)

The total time (during the simulated period) when the mean air temperature in zone is above the cooling setpoint plus the tolerance parameter temp_tolerance_ULH given in System parameters. This measure is frequently used in ASHRAE standards.

Unmet hours (heating)

The total time (during the simulated period) when the mean air temperature in zone is below the heating setpoint minus the tolerance parameter temp_tolerance_ULH given in System parameters. This measure is frequently used in ASHRAE standards.

AHU

The name of the air handling unit.

Heating

Heating energy transferred by heating coils.

Cooling

Cooling energy transferred by cooling coils.

AHU heat recovery

Recovered heating energy in heat exchanger.

AHU cold recovery

Recovered cooling energy in heat exchanger.

Humidification

Energy required for humidification.

Fans

Total fan electric energy.
