I am modelling a full natural ventilation strategy for a residential building that uses night time cooling for summer. I initially tried adding the natural ventilation for the thermal zones using OS:ZoneVentilation:DesignFlowRate but my results were inaccurate. In summer the zone temperature is almost 10 degrees warmer than the outdoor. and changing the flow rates seemed to be making no difference.
I then added the measure ZoneVentilation:WindandStackOpenArea based on the replies to previous messages but i still get the same exact results. Any advice?
