How can I define openable window (half open) in Energy+?
Hi i want define openable window in energy+, i use tool Zone:Ventilation:WindandStackOpenArea. Before I created new schedule for night ventilation, which was used in Zone:Ventilation:WindandStackOpenArea. When I get outputs i have problem with ari change rate, the value are 45 ach. Where i made mistake? It is nessesary set something else? I tried change opening area from 1,7m2 to 0,455m2 but air change rate was still 45ach, what is strange for me. Thank you
Can you paste your
ZoneVentilation:WindandStackOpenAreaobject so we can look at what you put in it?Hi, i used this setting: opening area: 1,72m2 (high: 1,15m width: 1,5m), opening effectivness: autocalculate, effective angle: 127 (east), height difference: 1m, discharge coeffficient for opening: autocalculate. Then air change rate is 89,7 ach, volume of my zone is 47m3. I didn't set temperature and wind speed limits, i want investigative what happened when window is open during night (i setted schedule for window openable). I checked weather data- wind speed was around 3 m/s. Also I want ask you if it possible set with this tool se angle for ventilation of window (for example 10°) Thanks
