Cymap - Calculate natural ventilation infiltration rate

By Ashley Rice

Within the room profiles, the user can calculate the infiltration rate in ac/h by using the Infiltration Guide built into Cymap in a CIBSE based project.

The Infiltration guide as seen below will give the user guidance on the infiltration rate in air changes per hour by entering the factors that the guide takes into consideration.

The ac/h rate is updated as the factors are changed. Click ok and that infiltration rate is applied to the room profile ventilation dialog.
