Hello, We have a project that consists of renovating 3 separate spaces in a large commercial building.

Hi, In our project, a particular zone (Board Room) is being served by 2 systems: central chiller plant through an AHU & by Cassette Units.

We are working on a plaza which have office spaces. we submit this project. But in the review report they asking the following documents.

I have roof top units. Each serves several rooms. One system serves a single room with single thermostat.

Hello, I'm currently working on a project of a huge supermarket. The building has warehouses and storage rooms.

Office floor of a high rise building trying to obtain LEED sliver. Floor is served by AHU, which serves 30 other floors not in scope. VAV's serve multiple zones on this floor.

I'm in a bit of a funk. I have a office space that populates two floors of a building.

I recently received a Design Review comment advising that the IAQ procedure included in Chapter 6 of the ASHRAE 62.1-2007 is not an acceptable tool to demonstrate compliance.

In the 62MZ calc, i created zones that have heating and potentially critically zones, but im having an issue with the results; for Vdzd, i enter the airflow rate that corresponds to the minimum VAV
