[Equest-users] LEED and Seasonal operation / DHW heater seasonal operation

Hi all,

I'm currently modelling a school building in eQuest for the LEED for
Schools 2009 certification. The school doesn't operate at all in the summer
season (closed) and so it isn't equipped with equipment for cooling.

I have made schedules modelling this principle (not operating in
JUNE/JULY/AUGUST) at both proposed and baseline scenarios but I'm concerned
if it is mandatory or not to model a full year's operation under LEED. In
the months of operation, I have modelled both cooling/heating as it is

A second question is how to make the DHW heater not to operate at the
summer months. Having tried everything and after doublechecking that there
is no DHW demand from the annual schedule for the summer months, the result
is that the DHW loop and pump show no use for these months (seen at the
simulation output) but still the DHW heater is operating consuming
significant gas for an unknown reason. Loop is set to demand operation and
recirculation set at 0.01.

Any help highly appreciated. Thanks in advance!
