The project I am working on is a bus station that has an enclosed retail area with an underground parking and an outdoor above ground parking space. The building will use natural/mechanical ventilation but no AC system, but for simulation purposes we are using a HVAC system according to Table G3.1.1A & B.
The underground parking will have some retail spaces but the outdoor parking will have lighting as the sole load
My question is:
Do I have to consider the underground parking as served by the HVAC system? What happens with the outdoor parking space, can I simulate it as external lighting?
I am using eQuest 3.64 by the way.

The parking garage that is only ventilated would not count as conditioned square footage at all and you would only model the ventilation. The retail spaces at the parking garage level would be modeled with the same system as the rest of the building based on the conditioned square footage and number of floors according to Table G3.1.1A.
Any parking lot with lighting only is modeled by including the lighting only.

How do you assign different electric meters in eQuest for tenant spaces and building core? Is it possible to graph multiple electric meters?

Hi Donovan, This is a good question to post on the eQuest users mailing list, since it's more about how to use eQuest than it is about LEED.

The client has made some changes to the original building, now I have one main enclosed building with underground parking, surrounded by a contiguous parking lot. In the parking lot there are: a small one story building for administrative purposes (gross floor area of 96m²), two waste water treatment plants, that serve the main building, a pumphouse for the water supply system and several guardhouses.
The auxiliary buildings serve the main building and are connected to it by the plumbing system and the lighting system.
The issue is that I don’t know if I should consider this as a multiple building project or as a single building project, since the auxiliary buildings are not contiguous to the main building but separated by the parking lot.
The MPR Supplemental Guide says that I must include the building in its entirely and that the building project must include all the land that support the normal building operation.
Also, If I consider the buildings as separate, the waste water treatment plants and the administrative building do comply with the minimum floor area but the guardhouses and the pump house have way less than the required 93m².
Should I consider the auxiliary buildings as separate projects and simulate them separately or as a single building?
The MPR Supplemental guide says that I should not include the parking garage in the gross floor area of the LEED project building. In that case what happens with all the lighting?

Thank you for your answers Marcus & Nadav, I really appreciate it .
I've been reading the MPR supplemental guide and, as I understand, we will have to submit a multiple building application. Since some of the buildings do not comply with the minimun area requirement, they won't be elegible for certification.
The water supply system, for the main certifiable building, is in one of those buildings that wont be elegible for certification. Now, my main question is if we have to exclude the water supply system of the main building and in the eQUEST simulation?
Thank You
