Activity tab in model data
Check the Computers > On checkbox to model the heat emissions and fuel consumption due to computer gains and other related IT equipment in the simulation.
Set the design level of energy consumption due to computers. Depending on the Equipment gain units model option setting, the gains data is entered either as Absolute zone power (in W) or as Power density (in W/m2 or W/ft2).
The fuel is assumed to be electricity, all gains are assumed to be emitted to the space.
Select the schedule that governs the timing of gains in the zone. The level of gains are multiplied by the time-varying factor in this schedule to give the gain for each timestep in the simulation.
This field is a decimal number between 0.0 and 1.0 and is used to characterise the amount of long-wave radiant heat being given off by computer equipment in a zone. The radiant fraction will be multiplied by the total energy consumed by electric equipment and (1-Fraction lost) to give the amount of long wavelength radiation gain from computer equipment in a zone. A value of zero means that the heat gain is entirely convective in which case all the heat is transferred to the air node in simulations. A value of 1 means that the gain is entirely radiative in which case all the heat is distributed to the inside surfaces. a typical value is somewhere between 0.1 and 0.2.
If the Internal gains operate with occupancy model option is not selected you can also set the operation schedule.
