Hello, I am curious about implimenting natural ventilation in climate zone 6 where the winter temperatures can be very cold.

Dear All:- we have some doubts in Ez (ZONE AIR DISTRIBUTION EFFECTIVENESS) selection in ventilation design we are supply fresh air using Fresh air fans, ERV, Treated fresh air units, Evaporative

We have an apartment building in which we have both mechanical ventilation and natural ventilation.

Hello everyone, I am working on the documentation of a Multi zone project for the cooling conditions in this case should the "Zone Primary Air flow Vpz" be equal to the "Zone Discharge Airflow Vd

Hi, I am working on a hospital project with a vast amount of different space types.

I' m currently working on a school project where most of the corridors have an exhaust system, that induces make-up air from the adjacent classrooms and (eventually negligible) infiltrated air dire

What is the difference between breathing zone outdoor airflow and room outdoor airflow rate? How do I find the room outdoor airflow rate for bedroom/living room type spaces Thanks.

I noticed, I cannot enter rooms that require exhaust like restrooms and lockers. Do I exclude them on the excel spread sheet?

we have a new addition added to an existing facility.
