Re: [TRNSYS-users] LEED certification

[David BRADLEY <d.bradley@tess-inc.com>]

Christophe,
  Yes, TRNSYS complies with Section G2.2 including the requirements of Standard 140. We have used TRNSYS successfully in about 15 LEED projects (one of which was LEED-NC 2009). The "BEPS" and "BEPU" documents are default reports that are produced by DOE2 (and are therefore easily obtained and submitted if you use eQuest). They group all of the building's energy use into a few categories and then report totals for each category on a monthly basis. For example, you would have a report item for the monthly space heating requirements of all the devices in the building that provide space heat. As I am sure you know, TRNSYS does not have any default reports like that so I use Type46 in the mode where it produces both an hourly and monthly integrated output file. I then take those result files and paste them into an Excel spreadsheet that I use to summarize it all for LEED. For example, I would send the compressor power used by each heat pump in the system when in heating mode to the Type46 printegrator seperately. I would then use Excel to sum up all of the compressor power in heating mode for all of the heat pumps in the building. I have had a few reviewers ask for the default reports so I include an explanation in my energy model narrative explaining my process. I have posted my Excel sheets for the reviewer to see in a few cases.
Best,
 David

Dear all,

 

In order to pass LEED certification, can you confirm if the software complies with ASHRAE 90.1-2007 Section G2.2 including meeting the requirements of ASHRAE Standard 140 for LEED-NC 2009 projects ?

Otherwise, can we use TrnSys for LEED certification ? Are others projects done in that way ?

Also, are we capable to perform BEPS and BEPU documents required in LEED certification ?

 

Thanks for tour time and answers,
