[Equest-users] Non conditioned regularly occupied space

[Singh, Arvind]

Hi Vamshi,

Based on your sqft and fuel size you will have system type and that will be system 6 in your case. Baseline model and proposed both will need heating and cooling system for non-conditioned space. But you can set up high cooling set point for baseline and proposed model to avoid any cooling in the non-conditioned space.

Thanks,
Arvind

Dear David,

The 95,000 ft2 area has only normal ceiling fans.

As I read in ASHRAE 90.1, it says, we shall model HVAC (Cooling or Heating) even if there is NO system proposed. But in this case, VRV system is proposed for 5000 ft2 area, so how shall I proceed with the remaining 95,000 ft2 area?

Thanks,
Vamshi.

Just to clarify - does the remaining 95,000 ft2 of regularly occupied office have an engineered natural ventilation scheme?

There are some cases where 90.1 asks for cooling systems to be modeled even if none are proposed. You'll need to find out if those conditions apply to you.
