Our project is use VRF system to keep the space cool. We also provide dedicated injection fan (DOAS) as to meet 62.1 requirement. Most space will have indoor cassette unit.

Is it safe to say that if a project acjhieves 60% improvement over ASHRAE 62.1 outdoor air ventilation rate that the project would be likely to receive an innovation credit if applied for?

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.

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.
