Heating and Cooling system availability schedules
The UsageZone class enables to specify schedules for heating and cooling set-point temperatures. It is implicitly assumed that the corresponding building systems are operating at any time. In practice, building systems may be not available at specific times of the year (e.g. heating in summer times) or of the day. At the moment, this could only be realized by specifying very low set-point temperatures for heating (or very high temperatures for the cooling system).
In order to decouple system set-point temperatures and system availability, it is proposed to introduce 2 new poptional properties in UsageZone:
heatingAvailabilitySchedule: DailyPatternSchedule[0..1]
coolingAvailabilitySchedule: DailyPatternSchedule[0..1]
In both schedules, there are only the values 0 (not available) and 1 (available).
