scope:

This standard specifies the formats to present schedule and condition of building, zone and space usage, which shall be referred as input data of energy calculations for non-residential buildings. The schedule and condition include schedules of occupancy, operation of technical building systems, ventilation rate, hot water usage and internal heat gains due to occupancy, lighting and equipment. This standard also gives categories of building, zone and space according to differentiating schedule and condition. Depending on necessary minuteness of the energy calculation, different levels of schedule and condition from the view point of time and space averaging are specified. The values and categories for the schedule and condition are included informatively. It should be noted that the schedule and condition in this international standard is basically different from assumptions in order to determine the size of technical building systems in the process of design, where possible largest values should be assumed. Instead, most usual and average values, which are assumed for the building energy calculation, are dealt with in this standard.
