Ventilation Rate Procedure is outlined in ASHRAE 62.1.2007.
DSM Modeling must use a suitable weather file representative of the project location. Also
include within the narrative details of how the project has been designed in relation to
CISBE Applications Manual 10:2005. Simulations of typical floors will be accepted where it
can be demonstrated that this approach is a reasonable approximation of anticipated
performance.
‘Return point’ typically includes return ducts for VAV systems, and spigot / bell mouth
returns in ceiling voids for FCU systems.
‘Dynamic Simulation Modelling (DSM)’ software must be capable of simulating a minimum
of 8760 hours based on historic weather data. In this credit, the software must be capable
of modeling inter-zonal air movements, thermal comfort, internal CO2 levels and, for
Mixed Mode buildings, allow window opening controls to be set based on internal and/or
external temperature.
‘Open area’ must be calculated by the design team and these areas must be consistent
where relied upon in any energy or thermal modeling (for example in RE-R1, RE-1, or LBi-
5.3).
