Subject: [Equest-users] Modelling Non AC building in eQUEST
Dear eQuesters,

I have the following doubt.

1. This is a hostel building. all the rooms are non ac except the wardens
cabin and the counselling room. These two rooms have split units.

[SK]: So you can have only these rooms to be conditioned.


2. I have to model this for thermal comfort compliance - so i need to show
that there are less unmet hours in the building.

[SK]: You can also provide the SS-O and SS-N reports for showing thermal
comfort conditions.

How do I go about this?

What i thought was as under,

1. I made the entire model and assigned the ac and non ac spaces as per
design.

2. I plan to put a system in the non ac rooms, such that the CFM generated
due to ceiling fans can be put as Fan Flow Parametres. A 12 hour fan
schedule (as per the evening + night time occupancy hours) can be assigned
to this. Other than this there will be no input parameter assigned to this
system - no COP, no efficiency. Other than this these rooms have to behave
as non ac spaces.

[SK]: To make any building non-ac you are required to have the FAN switched
off for 24 X 7 hours.
You are required to have OFF FAN schedule for the systems serving the
non-ac areas.
In this way you can have those areas as being served by not any HVAC fan or
then there is no HVAC there installed.
You can put any system and have the zone under it and then have all the
time HVAC Fan to be switched off.


Now my questions,
1. Do you think this is logical way to do?

2. Is there any other way to go about this?

3. If what i have described in point 2 is okay, while i assigning systems
what should it be? Like Sum or FNSYS or VAVS etc? Please let me know the
specifics

[SK]: I think this is the most simple way to do which i have suggested.

Please give me an insight into this ya.

Regards
Kirti
