Re: [EnergyPlus_Support] Heating load
The heating load problem is due to invalid values in the "Control Type SCHEDULE
Name" for ZONE CONTROL:THERMOSTATIC. This run uses thermostat control type 1
(Single heating setpoint) and control type 2 (Single cooling setpoint). With
these thermostat types, the control type schedule must contain values of 1 to
indicate when heating is available and 2 to indicate when cooling is active.
The specified schedule, "yearly", contains values which are all less than 1.0,
which is interpreted as control type zero which means no heating or cooling.
See the Input Output Reference, p. 630 (pdf p. 658) for more explanation of the
thermostat control type.
Also, I notice that the same schedule name "yearly" has been used in the PEOPLE
object for "Number of People SCHEDULE Name" and for "Activity level SCHEDULE
Name". This fractional schedule is appropriate for the number of people, but
the activity level schedule is in W/person (not a fraction) and should have
values in the range of 100 to 900 W/person. See the Input Output Reference, p.
193 (pdf p. 221) for more explanation.
