Hello everyone,

We are working on a project - 5 floors and greater than 200,000sf. Each floor has spaces with different temperature and humidity requirements.

For example
Space type 1: 70F - 50% RH Strict control
Space type 2: 70-75F 40% min - 60% max RH,
Space type 3: 70-75F 50% max RH summer only

This happens on all floors.

Proposed zoning has spaces combined on the basis of different environmental requirements.

How would you approach the zoning for the ASHRAE Baseline?

1.
One System 7 per floor: If we do floor by floor, we will be adding system level humidification for all spaces on that floor and allow whatever happens to each room. Definitely might end up humidifying spaces that don't need humidification
2.
Multiple Systems per floor: Split up each floor zoning by temp and humidity and have multiple Sys 7's per floor.
3.
Alternative Approach??

What do you all think? I am inclined to start with 1 system 7 per floor and stick with the ASHRAE requirements.

Thank you

Madhav
