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
