[Equest-users] ASHRAE90.1 Baseline System

[Demba Ndiaye]

Praveen,

Assuming you are applying for LEED 2009, you might consult the "2010 LEED Application Guide for Multiple Buildings and On-Campus Building Projects".

This document is available here https://www.usgbc.org/ShowFile.aspx?DocumentID=7987.

There is also another Guide that was published in 2005 I believe and that apply to earlier versions of LEED.

I have yet to try what you are doing but you would need to treat each building separately.  The number of floors in the building will determine your baseline building as Nick pointed out.  Your method to deliver conditioned air to each zone in each building is going to be separate even though you may use a plant to provide for example, hot and cold water to both buildings.  I haven't looked ahead to see if you are going to run into a system type conflict between the 2 buildings but if you do just use common sense and determine what is the best way to go to maximize energy efficiency.  None of the "rules" are written in stone.  They are bendable if you have a good argument and can back it up with hard data which eQuest will give you.

Thanks for your reply

Nick, I have created both building in one single model to take benefit of shading of building also as one single leed project.
I am still not able to decide while choosing baseline building; number of floors should be sum of all floor in project  or maximum number of floor of building.

That's what I'd do (but I'd also ask the lists to be sure)!

The only real distinction (and potential for a problem) here is that you have two buildings in one model.  Provided you continue to treat each building separately, both in building your baseline and in documentation, I don't see any base reason why a reviewer would reject the models.

Can anyone share a successful 2-building-1-model submittal experience to confirm this alone isn't an issue?

Prateek,
The first column for table G3.1.1A says for Non residential 5 floors or less and 25,000 SF to 150,000 SF. I think your sytem should fall under this and so Baseline System 6 should be the right choice. I dont know if adding the floors on the two buildings is a good idea !!
Anyone else in support or in disagreement with my comment ?

Dear All,

I am working on a project which has two towers within the same LEED boundary. One tower is 3 stories and another is 4 stories. Total conditioned area of the project is 70000 ft2. Heating type of my project is Electric.
In this case, what can be project baseline system? Should I choose baseline system 6 or baseline System 8?


Thanks in Advance
