[Bldg-sim] Mass Stretch Code: TEDI calcs

[smartin at shaunmartinconsulting.com]

Hi Madhav,

 

TEDI is a metric for the building envelope and ventilation load performance.
You can sum heating (ONLY) coil loads to determine the output.  This is a
clip from the guideline we use in Canada (BC) that explains it.  M.F.Area is
building area excluding unconditioned indoor parking area, but including all
other partially and unconditioned areas. So yes, the answer is option B,
excluding the cooling.  It is not the peak (A) and does not include heating
system efficiency (C).

Hi group,  

 

Hope everyone is doing well. We are working on a school building in MA and
need to perform "TEDI" models. I've read through the documentation and am a
little confused if it's a load metric or an energy metric. The limits are
expressed in kBtu/sf/year in the code language, but some of the supporting
documentation about how to extract this from equest/IES/ energy plus makes
me feel like it's a load metric. It has to be one the three and it seems
like its option B

 

A.	Peak Heating and Cooling load per SF
B.	Sum of annual heating and cooling loads (annual) per SF - without
efficiency accounting 
C.	Sum of annual heating and cooling energy per SF - with efficiency
accounting

Appreciate your responses! 

 

Thank you
