[Equest-users] ASHRAE Baseline EUI

[Nick Caton]

I was just suggesting the same thing...

 

E-star's target finder is not the most crystal-clear of tools, but does
pretty much deliver what you're looking for.

 

Some nuances:

 

Choosing various energy sources (i.e. Grid Electricity vs. Bituminuous
Coal) does have an effect on the CO2 emission calculations, but not on
the resulting target/average energy results.  Those energy figures are
not affected by the region your project is in, so it would be a stretch
to say you're getting a baseline of "Warehouses in Chicago."  You will
however get a baseline btu/sf/yr that corresponds with your building
occupancy and size.  

 

For further reading, I've attached a document I received on request from
the EPA, which details how source energy is dealt with currently... it's
informative if you need/want to understand what exactly the e-star
target finder tool is doing with regards to those "source energy" inputs
- which can have somewhat unintuitive effects on the results that are
churned out.

All,

 

I have developed a baseline building and calculated its energy use index
(EUI), total source building btu use divided by building square footage,
and I am curious to compare it to other models.  Obviously since many
users on this list are from very different climate zones, we will get
some varying answers.  However, I would still be interested to see what
kind of use different buildings are characterized by, especially in
Michigan.  Or, if any of you know a resource that I can use to reference
this type of information, I'd be grateful.

 

Thanks!
