� Spreadsheet listing of each zone including its reference name, zone floor area, zone
air temperature, zone resultant or operative temperature, zone peak cooling loads
and floor peak simultaneous cooling loads; and
Submission of spreadsheet results and associated plans for ‘typical floors’ will only be
accepted where equivalency can be demonstrated.
� Updated narrative describing how the project meets the Credit Requirements. Zoning
must match that in Credit RE-R1 Minimum Energy Performance;
� As-built drawings of the mechanical ventilation systems, clearly indicating zone
boundaries and zone references. Drawings must also highlight locations for
thermostatic controllers intended for occupant control;
� Spreadsheet listing of each zone including its reference name, zone floor area, zone
air temperature, zone resultant or operative temperature, zone peak cooling loads
and floor peak simultaneous cooling loads; and
� Extract from IDP-R4 Commissioning report verifying the individual zones operate as
intended.
Submission of spreadsheet results and associated plans for ‘typical floors’ will only be
accepted where equivalency can be demonstrated.
Modeling Guidelines:
� Modeling of zonal cooling demand must be undertaken by dynamic simulation
modeling software;
� The sizes of zones must not exceed the credit requirements;
� Cooling demand for each zone must be determined in relation to the design basis for
humidity and temperature set-points;
� Schedules for occupancy, small power and lighting must be accounted for;
� The building envelope thermal parameters and any associated shading must be
reflected in the model; and
� For each zone, extract the peak cooling demand and at this hour, extract the air
temperature and resultant or operative temperature.
Perimeter space includes those areas that have a thermal connection to the outdoors
through the façade of the building. Typically these areas will experience higher thermal
loads as a result. The depth of perimeter thermal zones must be 5m from the perimeter
wall.
Internal space includes those areas that have no thermal connection to the outdoors
through the façade of the building. Interior spaces are those spaces that extend beyond
5m from the perimeter wall.
